After an Intratympanic Steroid Injection: Ear Fullness, Dizziness and What to Report

Key Takeaways
- Ear fullness after an intratympanic injection is mostly the volume of fluid behind the eardrum and should improve over hours to a couple of days, not worsen.
- The brief spinning immediately after injection is a temperature effect on the balance organ, which is why many teams warm the solution and ask you to lie still.
- A bitter or metallic taste afterwards comes from the solution touching the chorda tympani, a taste nerve that crosses the middle ear, and typically fades the same day.
- For sudden hearing loss, the AAO-HNS guideline recommends salvage intratympanic steroids within two to six weeks of onset and a follow-up audiogram within six months.
- Because the steroid is delivered locally, systemic effects such as raised blood sugar and sleep disturbance clustered in the oral-steroid group, not the injection group, in the JAMA comparison trial.
- The NHS notes most eardrum perforations heal within a few weeks and some within a few months; until a clinician confirms closure, keep the ear dry and avoid forceful nose-blowing.
After an intratympanic steroid injection, most people notice temporary ear fullness, muffled hearing and brief dizziness that settle within hours to a few days, along with occasional mild pain, a metallic taste or a short change in tinnitus. Serious problems are uncommon. Report worsening pain, fever, drainage, spinning vertigo that persists, or a sudden further drop in hearing to your care team promptly.
The chair tilts back, the ear is numbed, and then there is the strange sensation of liquid arriving somewhere it has never been. You are asked to lie still, head turned, not to swallow more than you must. The clock on the wall becomes very interesting. When you finally sit up, the world lurches for a second, your ear feels stuffed with cotton, and a faint bitterness sits on the back of your tongue. Nobody warned you it would feel quite like this.
This is the ordinary experience of intratympanic steroid injection side effects, and almost all of it is expected. The procedure delivers a corticosteroid, an anti-inflammatory medicine, through the eardrum into the middle ear so it can reach the inner ear directly. It is used for sudden hearing loss, Ménière’s disease and a few related conditions.
What follows is a plain account of what those first hours and weeks tend to feel like, which sensations are the medicine doing its job, and which ones deserve a phone call.
What actually happens during an intratympanic steroid injection
An intratympanic injection means a medicine is placed behind the eardrum, in the air-filled middle ear, rather than into a muscle or vein. The eardrum, or tympanic membrane, is a thin sheet of tissue about the size of a small fingernail. Behind it sits the middle ear, and at the back of that space is the round window, a soft membrane that opens onto the fluid-filled inner ear where hearing and balance are sensed.
The appointment is usually done in an outpatient room with you awake. The clinician looks through a microscope or endoscope, numbs the eardrum with a topical anesthetic (a numbing agent applied to the surface), and passes a very fine needle through the membrane to deposit a small volume of steroid solution. The most common steroids used for this purpose are dexamethasone and methylprednisolone, both corticosteroids; which one, how much and how often is a decision for the treating team, and this article does not offer any dosing information.
Once the fluid is in, gravity does the rest. You are positioned with the treated ear facing up so the solution pools against the round window and soaks through into the inner ear. That is why you are asked to stay still and to limit swallowing or talking: each swallow briefly opens the Eustachian tube, the passage connecting the middle ear to the back of the nose, and can let the medicine drain away before it has been absorbed.
The needle puncture is tiny and, in most people, seals within days. According to the American Academy of Otolaryngology’s clinical practice guideline on sudden hearing loss, the procedure is generally well tolerated, with transient pain and dizziness being the most frequent complaints and persistent perforation uncommon.
Why intratympanic steroid injection side effects are usually short-lived
Understanding the mechanism makes the side effects far less alarming, because most of them are physical consequences of putting liquid into an air space.

The middle ear is designed to hold air. Sound reaches the eardrum, the eardrum vibrates, three tiny bones carry the vibration to the inner ear. Introduce even a small pool of fluid, and the eardrum cannot move as freely. Hearing dulls, voices sound as though they come from another room, and the ear feels full. This is the same reason a bad cold or a plane descent leaves you feeling underwater. As the solution is absorbed through the round window and the remainder drains down the Eustachian tube over the following hours, the eardrum regains its freedom and the fullness lifts.
Dizziness has a similarly mechanical explanation. The inner ear’s balance organs respond to temperature. Fluid that is cooler than body heat, arriving next to the inner ear, creates a small temperature gradient that the balance system misreads as movement. Clinicians call this a caloric response, and it is the same phenomenon used deliberately in balance testing. Many teams warm the solution beforehand for exactly this reason, and the effect fades as the temperatures equalize, typically within minutes.
The steroid itself is a different matter. Corticosteroids reduce inflammation and swelling in the delicate structures of the cochlea, the snail-shaped hearing organ. Because the medicine is delivered locally, only a small fraction reaches the bloodstream, which is why the whole-body effects of steroid tablets, discussed later, are largely avoided. The National Institute on Deafness and Other Communication Disorders (NIDCD) describes this local route as a way to deliver the medicine directly to the inner ear while limiting systemic exposure.
Who is usually offered it, and who is usually asked to wait
Three groups of people meet this procedure most often.
The first is people with sudden sensorineural hearing loss, meaning a rapid drop in hearing over hours or up to three days that comes from the inner ear or hearing nerve rather than from wax or fluid. The NIDCD notes that this affects roughly one to six people per 5,000 each year and should be treated as a medical urgency. The American Academy of Otolaryngology guideline lists intratympanic steroids as an option both as initial treatment, particularly for people who cannot take oral steroids, and as salvage therapy, meaning a second attempt, when hearing has not recovered after oral treatment. The guideline recommends that salvage injections be offered within two to six weeks of the hearing loss beginning.
The second group has Ménière’s disease, an inner-ear disorder producing episodes of spinning vertigo, fluctuating hearing loss, tinnitus and ear fullness. Here, according to the NIDCD and the NHS, intratympanic steroids are one of several options considered when diet and daily medicines have not controlled the vertigo attacks.
The third, smaller group includes people with certain autoimmune inner-ear conditions, where the treating specialist judges local steroids worth trying.
Who is usually asked to wait or to consider something else? People with an active middle-ear infection, since injecting through an inflamed eardrum risks spreading infection inward. People whose eardrum has not healed from a previous procedure. Those whose hearing loss turns out to have a different cause on examination, such as impacted wax or a middle-ear effusion. And anyone in whom the timing has passed the window where evidence suggests benefit; the guideline advises against routinely offering the injection more than six weeks after sudden loss. In every case, the decision rests with the treating team after an ear examination and a hearing test.
Ear fullness after the injection: what it is and how long it typically lasts
Fullness is the sensation people mention first, and it can be unsettling precisely because fullness was often part of the original problem. Was the treatment making things worse?

Almost always, no. In the first hours the fullness is simply the volume of fluid sitting behind the eardrum. Hearing in that ear is temporarily muffled, your own voice may sound loud or echoey, and the ear can feel pressurized, as though it needs to pop. As the solution absorbs and drains, usually over the rest of the day, that layer of fluid thins and the sensation eases. Some people describe a second, milder wave of fullness over the next day or two, which is thought to reflect the small amount of local irritation and swelling that any puncture produces while it heals.
What you can reasonably expect is a trend, not a switch. The fullness should be at its worst in the clinic room and progressively better afterwards. If it plateaus or climbs over several days, especially with pain or discharge, it is worth a call, because a persistent middle-ear effusion or infection can produce the same feeling.
There is one important exception to the reassurance. In Ménière’s disease, fullness is itself a symptom of the condition and can fluctuate independently of the injection. If you have Ménière’s and your fullness comes and goes over weeks in the pattern you already know, that is more likely the disease than the treatment. Keeping a brief symptom diary, noting when the ear feels full and whether it travels with vertigo or hearing change, gives your specialist something concrete to work with at follow-up.
Do not try to relieve the pressure by forceful nose-blowing or by pinching your nose and pushing air into your ears. The puncture is still sealing, and pressure from the Eustachian tube side can push air or fluid through it.
Dizziness after ear steroid injection: the caloric effect and what is normal
Dizziness after ear steroid injection is common, brief, and worth describing precisely, because the word covers several very different experiences.
The typical version arrives within a minute or two of the injection: a spinning or swaying sensation, sometimes with nausea, that peaks quickly and subsides as you lie still. This is the caloric response described earlier, the inner ear reacting to a temperature difference. It lasts minutes rather than hours. Clinicians reduce it by warming the solution and by having you rest before standing, and most people can walk out unaided after the waiting period.
A second, subtler version is a sense of imbalance for the rest of the day, a feeling of walking on a boat or of the floor being slightly unreliable. This is usually the residue of the initial stimulation combined with the muffled hearing on one side, which changes how your brain weighs its sensory inputs. Moving slowly, avoiding sudden head turns and not driving until you feel steady are sensible precautions, and many teams ask that someone else takes you home after the first injection.
What is not typical is spinning vertigo that continues for hours, returns in waves, or arrives with vomiting, a marked new hearing drop or a loud roaring tinnitus. In someone with Ménière’s disease, this may simply be an attack of the underlying condition, which can be triggered by the stress or stimulation of the procedure. In someone without a vertigo history, it deserves same-day contact with the care team, because it can signal irritation or, rarely, infection reaching the inner ear.
The Rauch trial published in JAMA, comparing oral and intratympanic steroids for sudden hearing loss, recorded transient dizziness among the most frequent local side effects of the injection arm, and reported that it was self-limiting in almost every case. That pattern, uncomfortable but short, is the one to expect.
The full list of intratympanic steroid injection side effects, at a glance
Beyond fullness and dizziness, several smaller effects are common enough that you should not be surprised by them.
Pain is usually a sharp moment at the puncture followed by an ache for a few hours; the topical anesthetic blunts the first part, and the second usually responds to rest. A brief metallic or bitter taste occurs because the solution can reach the chorda tympani, a taste nerve that crosses the middle ear on its way to the tongue; it typically fades within the day. Tinnitus, the ringing or hissing you may already have, can grow louder or change pitch for a day or two and then return to baseline. A small amount of fluid or blood-tinged discharge from the ear canal in the first day is usually the solution and the anesthetic finding their way out.
| Effect | Why it happens | Typical course | Report if |
|---|---|---|---|
| Ear fullness, muffled hearing | Fluid behind eardrum | Hours to a day or two | Worsening after day two, or with pain or fever |
| Brief dizziness | Temperature effect on inner ear | Minutes; mild imbalance up to a day | Spinning vertigo lasting hours, or with vomiting |
| Pain | Puncture, local irritation | Hours | Increasing pain over days |
| Metallic taste | Solution touching taste nerve | Same day | Persisting beyond a week |
| Louder tinnitus | Inner-ear stimulation | One to two days | Sudden roaring with hearing drop |
| Small discharge | Solution draining out | First day | Pus-like, smelly or bloody discharge |
| Persistent perforation | Puncture fails to seal | Uncommon; most seal in weeks | Ongoing whistling, water entry, drainage |
The American Academy of Otolaryngology guideline characterizes serious complications, including persistent perforation and middle-ear infection, as uncommon relative to the expected transient effects. The right-hand column is the practical takeaway: timing and direction of travel matter more than the symptom itself.
What not to do after an intratympanic injection
The instructions you are given in the clinic take priority over anything written here, because they are tailored to your ear and your team’s technique. That said, the advice most people receive falls into a few consistent themes, and knowing the reasoning behind each makes it easier to follow.
Do not rush the waiting period. The value of the injection depends on the solution staying in contact with the round window. Sitting up early, swallowing repeatedly, chewing gum or talking at length all encourage the fluid to drain down the Eustachian tube before it is absorbed. Bring nothing that will tempt you to move.
Do not get water into the ear until the puncture has sealed. The NHS advises people with any eardrum perforation to keep the ear dry, using a cotton ball coated in petroleum jelly or a fitted plug while showering, and to avoid swimming until a clinician has confirmed healing. Water carrying bacteria into the middle ear is the main route to infection.
Do not push air into the ear. Forceful nose-blowing, the pinch-and-blow maneuver used to clear ears on planes, and heavy straining all raise pressure on the far side of the eardrum. Blow gently, one nostril at a time, and sneeze with your mouth open.
Do not put anything into the ear canal. No cotton buds, no ear candles, no over-the-counter drops unless your team has specifically approved them; some drops are not intended for use when the eardrum is not intact.
Do not drive or operate machinery until you feel steady. Balance can be subtly off for the rest of the day even when the initial spin has passed.
Do not stop or alter any prescribed medicine on your own. If you are also taking oral steroids or other treatment, changes belong to the prescriber.
Flying is usually discussed individually. A sealed puncture is not a barrier to pressure change, but a healing one may be, so ask before booking.
How long does intratympanic injection take to work?
This is the question behind most anxious phone calls in the first week, and the honest answer is that improvement, when it comes, is measured in weeks rather than days, and it does not follow a neat schedule.
For sudden sensorineural hearing loss, the picture is complicated by the fact that hearing often improves on its own. The NIDCD reports that about half of people with sudden deafness recover some or all of their hearing spontaneously, usually within one to two weeks of onset. This makes the effect of any single treatment hard to feel from the inside: you may improve because of the injection, alongside it, or regardless of it.
The American Academy of Otolaryngology guideline frames expectations around measurement rather than sensation. It recommends a follow-up hearing test, an audiogram, within six months of diagnosis to establish the final outcome, and it notes that most recovery that will happen has happened within the first several weeks. Injections given as a course are typically spaced days to a week or so apart over a few weeks, though the exact number and interval are the treating team’s decision and vary between protocols. The JAMA trial by Rauch and colleagues, the largest head-to-head comparison of oral and intratympanic steroids for sudden loss, assessed hearing at two months after treatment began, which gives a sense of the timescale researchers consider meaningful.
For Ménière’s disease the goal is different: fewer and milder vertigo attacks rather than a change on a hearing test. Because attacks are episodic, it can take weeks to months of diary-keeping to know whether their frequency has genuinely fallen.
What does not happen is a sudden clearing of the ear the next morning. If anything, the day after an injection may feel slightly worse than the day before because of residual fullness. Judge the treatment at the follow-up audiogram, not in the bathroom mirror.
Eardrum healing after steroid injection: how long, and what slows it
The needle used for an intratympanic injection is fine, and the hole it leaves is correspondingly small. In most people the eardrum seals over within days, and the ear can be examined at the next appointment with no visible trace.
Healing takes longer in some circumstances. Repeated injections through the same spot give the tissue less time to recover between punctures. Middle-ear infection, whether pre-existing or introduced by water, delays closure. Smoking, poorly controlled diabetes and long-term oral steroid use all slow wound healing generally and can affect the eardrum too. Steroids themselves, placed locally, may modestly slow the sealing of the puncture, which is one reason clinicians examine the membrane before each further injection.
When a perforation does persist, the NHS notes that most eardrum perforations of any cause heal by themselves within a few weeks, and that some can take up to a few months; if a hole remains beyond that, an ear specialist may discuss options, which range from watchful waiting to a minor procedure to patch or repair the membrane. The American Academy of Otolaryngology guideline lists persistent perforation among the recognized but uncommon complications of the injection.
How would you know if yours has not sealed? Water entering the ear during a shower may produce a sudden cold sensation deep in the ear or a brief spin. Some people notice a faint whistling on nose-blowing, or intermittent watery discharge. Hearing may stay slightly muffled beyond the expected first days. None of these prove a perforation, but all justify asking for the ear to be looked at.
Until a clinician has confirmed the membrane is intact, treat the ear as if it were open: keep it dry, keep objects out, and keep pressure changes gentle. That short period of caution is the main thing within your control that protects healing.
What the following days and weeks usually look like
Timelines vary with the reason for treatment and the number of injections planned, but a rough shape recurs.
The first evening. The ear feels full and hearing on that side is dull. There may be a mild ache and a lingering odd taste. Balance is slightly uncertain, so most people take it easy. Sleeping with the treated ear upward for the first night is a common suggestion, both for comfort and to keep any remaining solution against the round window.
Days one to three. Fullness lifts, sometimes unevenly. Tinnitus may have shifted and then drifts back to its usual character. Any small discharge stops. Pain should be gone. People generally return to work and normal activity, with the ear kept dry.
The first week. If a course of injections has been planned, the next one often falls in this window. Before each, the clinician checks that the previous puncture has healed and that there is no sign of infection. This is also the point at which many people first try to judge whether hearing has changed, and the point at which it is worth remembering that early hearing fluctuation is common and not a verdict.
Weeks two to six. The course finishes. For sudden hearing loss, this is the window the guideline identifies as most relevant for recovery, and a repeat audiogram is often scheduled to compare against the baseline. For Ménière’s disease, the diary of vertigo episodes becomes the more useful measure.
By six months. The American Academy of Otolaryngology guideline recommends a final hearing assessment within this period to document the outcome. If hearing has not returned to a useful level, the conversation turns toward rehabilitation: hearing aids, assistive devices and, for profound loss in one ear, options your specialist can explain. That conversation is not a failure of the injection; it is the next step of the same plan.
What are the bad side effects of steroid shots, and do they apply to the ear?
People searching this phrase are usually thinking of the steroid injections given into joints, or of steroid tablets, and the reputation those carry: raised blood sugar, mood changes, sleep disturbance, fluid retention, weight gain, raised blood pressure, thinning bones with long courses, and stomach irritation. Those effects are real, and they are one of the main reasons the intratympanic route exists.
The distinction is where the medicine goes. A tablet or a muscle injection puts the steroid into the bloodstream, from which it reaches every organ. An intratympanic injection places a small volume in the middle ear, and most of what is absorbed enters the inner ear directly. The fraction that reaches the general circulation is small, so the body-wide effects listed above are largely avoided. The American Academy of Otolaryngology guideline specifically notes that intratympanic steroids may be preferred for people in whom systemic steroids are risky, such as those with diabetes, and the Rauch trial found the expected systemic effects, including glucose rises and mood or sleep changes, clustered in the oral-steroid group rather than the injection group.
This does not make the injected steroid inert. Local effects are possible: a slower-healing puncture, as discussed above, and, rarely, a sterile inflammatory reaction in the middle ear. People with diabetes are sometimes asked to check blood glucose a little more attentively for a day or two, not because a large rise is expected but because the drug is a corticosteroid and individual responses vary. Anyone already taking oral steroids for the same condition should know that the two routes add together.
The candid summary is that the serious side effects people fear from steroids belong mainly to systemic courses, and that the intratympanic route trades those for a set of local, mostly transient, ear-specific effects. Whether that trade suits you is a conversation to have with the prescriber, who knows your full history.
What people often get wrong about intratympanic steroid injection side effects
“Dizziness afterwards means the inner ear has been damaged.” The brief spin after injection is a temperature effect on a normally functioning balance organ, the same reaction used deliberately in clinical balance tests. It says nothing about damage. Prolonged vertigo is different and should be reported, but the momentary kind is expected.
“The hole in my eardrum will leave me with permanent hearing loss.” The puncture is tiny and seals in days for most people. Even when a perforation persists, the hearing effect of a small hole is modest and often reversible with repair. The hearing loss that brought you to the clinic is an inner-ear problem, which is a separate matter entirely.
“If I don’t hear better within a day, it hasn’t worked.” Recovery from sudden hearing loss unfolds over weeks, and the first day after injection is often muffled by residual fluid. The relevant judgment is the follow-up audiogram, not the next morning.
“Ear fullness means fluid is trapped and I need to pop it.” The fullness is expected and drains on its own. Forcing air into the ear risks disturbing the healing puncture and, in the worst case, pushing material into the middle ear.
“Steroid shots always cause weight gain and sleep problems.” Those effects belong to steroids circulating through the whole body. The intratympanic route delivers a small volume locally, and systemic effects are uncommon.
“More injections are always better.” Each puncture carries a small risk, and the evidence supports a defined window for sudden hearing loss rather than open-ended courses. The number of injections is a clinical decision balanced against healing and timing.
“It is a last resort.” For some people it is a first-line option, particularly when oral steroids are unsuitable. For others it is salvage therapy after oral treatment. Its place depends on the individual, not on a fixed hierarchy.
Questions to ask your care team
A short list, brought to the appointment, helps you leave with clear expectations rather than reconstructing them from the internet later. These are the questions that tend to matter most.
- What is the goal of this injection for me specifically: recovering hearing, reducing vertigo attacks, or something else? How will we measure whether it has helped?
- How many injections are you planning, roughly how far apart, and what would lead you to stop early or extend the course?
- How long should I expect the fullness, muffled hearing and dizziness to last after each injection, and at what point would you want to hear from me?
- How should I keep the ear dry, and for how long? When may I swim, and is flying a concern during the course?
- Are there any ear drops or other medicines I should avoid while the eardrum is healing?
- I am also taking oral steroids / I have diabetes / I take blood thinners. Does any of that change the plan or what I should watch for?
- What are the signs of a persistent perforation or an infection, and how quickly should I contact you if I notice them?
- Will you examine the eardrum before each further injection, and when is the follow-up hearing test scheduled?
- If my hearing does not recover, what are the next options, and when would we discuss them?
- Who do I contact out of hours if something feels wrong?
You are entitled to ask the team to write down the answers to the questions about timing and warning signs. Memory is unreliable after a procedure, particularly one that leaves you slightly dizzy and hearing on one side, and a written sheet spares everyone an anxious call over something that is entirely normal.
When to call your doctor
Most of what follows an intratympanic injection is expected and self-limiting. The signs below are the exceptions, and none of them should wait for the next scheduled appointment.
Contact your care team the same day if you notice:
- Spinning vertigo that continues for hours after the injection, returns in repeated waves, or comes with vomiting you cannot control.
- A sudden further drop in hearing in the treated ear, or a new roaring tinnitus that is clearly different from your usual pattern.
- Ear pain that increases over the first days rather than fading, or pain that spreads behind the ear or into the jaw.
- Discharge from the ear canal that is thick, pus-like, foul-smelling or bloody beyond the small amount expected in the first day.
- Fever, chills or feeling generally unwell in the days after the procedure.
- Persistent fullness, whistling on nose-blowing, or water entering the ear during washing beyond the first two weeks, which can indicate the puncture has not sealed.
Seek urgent or emergency care if you experience:
- Severe headache with a stiff neck, high fever and confusion or drowsiness.
- New weakness or drooping on one side of the face.
- Facial pain, swelling or redness behind the ear that is rapidly worsening.
- Sudden severe dizziness with double vision, slurred speech, difficulty swallowing or weakness in a limb, which are not ear symptoms and need immediate assessment for other causes.
These serious events are rare after intratympanic injection, but the middle ear sits close to the facial nerve, the inner ear and the lining of the brain, and infection in that space is treated promptly for good reason. When in doubt, call. A clinician would far rather examine a healthy, healing ear than learn about a problem late. Every decision about further treatment, including whether to continue a planned course, rests with the team caring for you.
Frequently asked questions
How long does it take for an intratympanic steroid injection to work?
Any benefit is usually judged over weeks, not days. For sudden hearing loss, the AAO-HNS guideline recommends a follow-up hearing test within six months, and most recovery that occurs happens within the first several weeks; the NIDCD notes that about half of people improve spontaneously within one to two weeks, which makes early self-assessment unreliable. For Ménière’s disease, fewer vertigo attacks over weeks to months is the measure.
What not to do after an intratympanic injection?
Avoid sitting up early or swallowing repeatedly during the waiting period, keep water out of the ear until the puncture has healed, do not blow your nose forcefully or push air into the ears, and do not put cotton buds or unapproved drops into the canal. Avoid driving until you feel steady. Follow your own team’s written instructions where they differ, and never change prescribed medicines without the prescriber.
Is dizziness after ear steroid injection normal?
Brief dizziness in the minutes after injection is common and expected. It is caused by fluid at a different temperature reaching the inner ear, the same reaction used in balance testing, and it settles as temperatures equalize. Mild imbalance can linger for the rest of the day. Spinning vertigo that lasts hours, returns in waves or comes with vomiting or a hearing drop should be reported the same day.
How long does it take for the eardrum to heal after steroid injections?
The needle puncture is small and in most people seals within days. Repeated injections, infection, smoking, diabetes and steroid exposure can slow this. The NHS notes that most eardrum perforations heal on their own within a few weeks and some take up to a few months; if a hole persists longer, a specialist may discuss repair options. Your clinician will examine the membrane before any further injection.
What are the bad side effects of steroid shots, and do they happen with ear injections?
The feared effects of steroids, such as raised blood sugar, mood and sleep changes, fluid retention and, with long courses, bone thinning, come mainly from steroids circulating through the whole body. Intratympanic injection places a small volume locally, and the JAMA trial comparing routes found those systemic effects clustered in the oral group. Local effects like fullness, brief dizziness, pain and a slower-healing puncture are the relevant ones.
Why does my ear feel full after the injection?
Fullness is expected because a small pool of liquid now sits in an air space designed to vibrate freely. The eardrum moves less, hearing dulls and the ear feels pressurized, much like during a cold or a plane descent. As the solution absorbs through the round window and drains down the Eustachian tube, the sensation lifts, usually within a day or two. Fullness that worsens with pain or fever should be reported.
Why do I have a strange taste in my mouth after the injection?
A bitter or metallic taste is common and harmless. The chorda tympani, a nerve carrying taste from the front of the tongue, passes directly through the middle ear, and the injected solution can bathe it briefly. The taste usually fades within hours. A taste change that persists beyond a week is unusual and worth mentioning at follow-up, though it almost always resolves on its own.
Can I fly after an intratympanic steroid injection?
Ask your care team before booking, because the answer depends on whether the puncture has sealed and where you are in a course of injections. A healed eardrum tolerates pressure changes normally; a healing one may not, and forceful ear-clearing maneuvers on descent are exactly what you are asked to avoid. Many people fly without difficulty once healing is confirmed, but the timing is an individual clinical decision.
Does the injection hurt, and how long does the pain last?
Most people describe a sharp moment at the puncture, blunted by the topical anesthetic, followed by a dull ache for a few hours. The American Academy of Otolaryngology guideline lists transient pain among the most frequent side effects and notes it is usually short-lived. Pain that increases over the following days rather than fading, or that spreads behind the ear, is not typical and should prompt a call.
What happens if the intratympanic steroid injection does not restore my hearing?
The treating team will confirm the outcome with a follow-up audiogram, usually within six months per the AAO-HNS guideline, and then discuss rehabilitation. Depending on the degree of loss, that may include hearing aids, assistive listening devices or, for profound loss in one ear, other options a specialist can explain. Not recovering hearing is a known possibility with sudden loss, and planning for it is part of the same care pathway.
