Why an MRI Comes Before Trigeminal Neuralgia Surgery: What the Scan Shows About the Nerve

The pain had a signature. A flash across the right cheek when she brushed her teeth, another when a breeze crossed the car window, each one over in seconds and each one worse than the last. By the time she sat in the neurosurgeon’s office, she had stopped chewing on that side and had learned to talk with her lips barely moving. She wanted a date for an operation. What she got first was a request for a scan.

That order feels like a delay to many people in her position. It is closer to a map. An MRI before trigeminal neuralgia surgery is the one test that can show the surgeon the thing they are planning to operate on: a tiny stretch of nerve, a few millimeters long, where an artery or vein may be lying against it.

This article walks through what the scan is looking for, what it genuinely shows, what it cannot prove, and how its findings shape the conversation about whether, and which, surgery makes sense.

What is neuralgia, and what makes the trigeminal kind different?

Neuralgia is pain that originates in a nerve itself rather than in the tissue the nerve serves. The tooth is fine; the wire reporting on the tooth is misfiring. Trigeminal neuralgia is neuralgia of the trigeminal nerve, the fifth of twelve cranial nerves, which carries sensation from the face in three branches: the forehead and eye, the cheek and upper jaw, and the lower jaw and chin.

Classic trigeminal neuralgia has a recognizable pattern. The pain is brief, electric and usually one-sided, lasting seconds to a couple of minutes, and it is set off by ordinary touch: chewing, shaving, a toothbrush, cold air, even speaking. Between attacks the face can feel entirely normal. Some people develop a duller background ache as well, a pattern the NIH’s National Institute of Neurological Disorders and Stroke (NINDS) describes as a less typical form. The condition is more common after the age of 50 and affects women more often than men, according to NINDS.

Why does the nerve misfire? In most cases the leading explanation is mechanical. Where the nerve leaves the brainstem, its protective coating is thin and vulnerable. A pulsing artery resting on that spot can, over years, wear at the insulation so that touch signals cross over into pain pathways. Less often the damage comes from a plaque of multiple sclerosis, a tumor, or a cyst in the same region. Occasionally no cause is ever found.

That short list of causes is the reason the scan matters. Each cause points toward a different plan, and only imaging can tell them apart from the outside.

Can trigeminal neuralgia be diagnosed by MRI?

Not on its own, and this is worth being clear about from the start. Trigeminal neuralgia is a clinical diagnosis, meaning it rests on the story you tell: the quality of the pain, where it strikes, what triggers it and how long each attack lasts. The Mayo Clinic describes the diagnosis as based mainly on the description of the pain and a neurological examination that tests sensation and the muscles of the face. The MRI comes afterward, to answer a different question: what is going on at the nerve?

Magnetic resonance imaging (MRI) uses a strong magnet and radio waves, with no X-rays, to build detailed pictures of soft tissue. For the trigeminal nerve, radiologists use thin-slice, high-resolution sequences that show fluid-filled spaces around the brainstem in bright detail, so a dark nerve and a dark vessel stand out against them. Some protocols add magnetic resonance angiography (MRA), a way of imaging blood vessels without a catheter.

What the scan can do is support the diagnosis and sort it into a category. International headache classification, which NINDS and the NHS both follow, divides the condition into three groups: classical, where a vessel is seen compressing and distorting the nerve; secondary, where the cause is multiple sclerosis, a tumor or another structural lesion; and idiopathic, where nothing abnormal is found.

So a scan that shows a vessel indenting the nerve strengthens the case for classical trigeminal neuralgia. A scan that shows nothing does not take the diagnosis away. Plenty of people with textbook attacks have unremarkable imaging, and plenty of people with no facial pain at all have a vessel touching the nerve. The scan is evidence, not a verdict.

Why an MRI comes before trigeminal neuralgia surgery

Think of the operation as a decision with three parts: is surgery reasonable, which surgery, and how exactly to do it. An MRI before trigeminal neuralgia surgery feeds all three.

First, the scan protects you from the wrong operation. If the pain is coming from a multiple sclerosis plaque in the brainstem, moving a blood vessel off the nerve will not help, because the vessel was never the problem. If a slow-growing tumor is pressing on the nerve, the plan becomes a conversation about that tumor rather than about neuralgia. Both the NHS and the Mayo Clinic list ruling out these causes as a central reason the scan is ordered.

Second, the scan helps match you to a procedure. Microvascular decompression (MVD), the operation that lifts a vessel away from the nerve and pads it, makes the most anatomical sense when the scan shows a vessel in contact with the nerve. Procedures that deliberately injure part of the nerve to interrupt pain signals, such as radiofrequency, glycerol or balloon treatments through the cheek, or focused radiation, do not depend on finding a vessel at all. People with a clear compression, people with a normal scan, and people with multiple sclerosis may each be guided toward different options.

Third, the scan is a rehearsal for the surgeon. Knowing before the first incision whether the offending vessel is an artery or a vein, whether it sits above, below or between nerve fibers, and whether more than one vessel is involved shapes the approach and the padding strategy. The scan does not replace what the surgeon sees under the microscope, but it means fewer surprises.

Ordering the scan is, in short, the step that turns a hope for relief into a plan grounded in what is actually there.

What is neurovascular compression syndrome?

Neurovascular compression, sometimes written as neurovascular conflict, means a blood vessel lying against a cranial nerve closely enough to irritate or deform it. Trigeminal neuralgia is the best-known example, but the same mechanism is blamed for hemifacial spasm, a twitching of one side of the face caused by a vessel on the facial nerve, and for a rarer throat and ear pain condition involving the glossopharyngeal nerve.

The vulnerable spot has a name: the root entry zone, the few millimeters where the nerve leaves the brainstem and switches from central-type insulation to peripheral-type insulation. That junction is a weak seam. Arteries at the base of the brain, particularly the superior cerebellar artery, loop close to it, and with age those loops often lengthen and sag. A vessel that once passed clear of the nerve may settle onto it. Each heartbeat then delivers a tiny pulse against the nerve, thousands of times an hour, for years.

The leading explanation, described by NINDS and Johns Hopkins, is that this chronic pulsing wears away the myelin, the fatty insulating sheath around nerve fibers. Bare fibers that carry light touch can short-circuit into neighboring fibers that carry pain, so a toothbrush is read by the brain as an electric shock. The fibers also become prone to firing in bursts, which fits the explosive, repetitive character of attacks.

A caution belongs here. Contact between a vessel and the nerve is common in people who have never had facial pain. What seems to matter more is the degree of contact: a vessel that visibly indents, flattens or displaces the nerve is more convincing than one that merely touches it. The syndrome is the combination of a compatible pain story and a convincing picture, not the picture alone.

What neurovascular compression on MRI actually looks like

Open the images and the first thing you notice is the brainstem, a thick stalk of tissue sitting in a bright pool of fluid. The trigeminal nerve emerges from its side like a cable leaving a wall, running forward through that fluid toward the skull base. On the thin-slice sequences built for this purpose, the nerve appears as a dark, slightly flattened cord a few millimeters wide. Blood vessels appear dark too, which is why the bright fluid matters: it is the backlight that makes both visible.

Radiologists then look at the relationship between the two. The usual descriptions, which you may see echoed on your report, run roughly in order of significance:

• No contact: the nerve runs through clear fluid with no vessel nearby.
• Contact: a vessel touches the nerve but the nerve keeps its shape.
• Distortion or displacement: the nerve is bent, indented or pushed out of its normal course.
• Atrophy: the nerve on the painful side is visibly thinner than the one on the other side, suggesting long-standing pressure.

The report will often name the suspected vessel. An artery is a more convincing culprit than a vein, because arteries pulse harder and are more reliably seen on the scan; small veins can be missed or can look different once the skull is opened and pressure changes.

Two features make the picture more persuasive. One is that the compression sits at the root entry zone rather than further along the nerve. The other is that the side of the finding matches the side of the pain. A vessel pressing on the symptom-free side is a reminder of how common harmless contact is.

None of this is read in isolation. The radiologist and the surgeon weigh the picture against the story in the clinic, and the surgeon often reviews the raw images personally rather than relying on the written report alone.

What actually happens during an MRI for trigeminal neuralgia

The appointment is more ordinary than the stakes suggest. You will be asked about metal in your body, because the magnet is powerful and always on: pacemakers, some older aneurysm clips, cochlear implants, metal fragments and certain pumps need checking in advance, and MedlinePlus advises telling staff about any implant, dental work or possibility of pregnancy. Jewelry, hairpins and cards with magnetic strips stay in a locker.

You lie on a narrow table, head resting in a cushioned frame called a coil, which is simply an antenna close to the area being imaged. The table slides into the tunnel. For a trigeminal protocol the head needs to stay very still, so staff may pad the sides and offer a mirror or music. The machine is loud; earplugs or headphones are standard. According to MedlinePlus, an MRI examination usually takes 30 to 60 minutes, and a dedicated nerve protocol with several thin-slice sequences tends toward the longer end.

Some protocols include an injection of contrast, a gadolinium-based dye given through a small cannula in the arm, which makes tumors and inflamed tissue stand out. Your kidney function may be checked beforehand if contrast is planned. The dye is not needed to see a vessel on the nerve, so not everyone receives it.

People who find enclosed spaces difficult should say so when the scan is booked. Options range from a wider-bore scanner to a mild calming medicine arranged by the prescribing clinician; the choice is theirs to make with you, and the scan cannot be rushed, because motion blurs exactly the fine detail the surgeon needs.

Afterward you can drive, eat and work as normal. The images go to a radiologist, who writes a report, and then to the surgical team, who look at the pictures with your particular pain in mind.

What else the scan rules out: multiple sclerosis, tumors and cysts

The same images that search for a vessel also search for things that should change the whole plan. This part of the scan deserves as much attention as the compression question, because it is where the most consequential surprises appear.

Multiple sclerosis (MS) is a condition in which the immune system attacks myelin in the brain and spinal cord. A plaque in the pons, the part of the brainstem the trigeminal nerve enters, can produce facial pain indistinguishable from classic trigeminal neuralgia. NINDS notes that trigeminal neuralgia in younger adults, or on both sides of the face, raises this possibility. On MRI, plaques appear as bright patches on certain sequences, and the surgeon’s question shifts from where to place a pad to whether a nerve-targeted procedure, rather than vessel decompression, is the better fit, alongside the neurologist’s management of the MS itself.

Tumors in this region are usually benign and slow-growing. A vestibular schwannoma on the hearing nerve, a meningioma arising from the brain’s covering, or an epidermoid cyst can each press on the trigeminal nerve from the side. They are uncommon causes of facial pain, but the Mayo Clinic lists them among the reasons imaging is routine, since their treatment is a different operation with a different set of considerations.

Less often, the scan reveals a tangle of abnormal blood vessels, a widened artery, or signs of a previous small stroke in the brainstem.

When the scan finds something unexpected, the news is unsettling but the logic is reassuring. The whole point of looking before operating is to make sure the operation chosen is aimed at the right target. A clean scan, with or without a vessel on the nerve, closes those doors and narrows the conversation to the choices that fit classical or idiopathic trigeminal neuralgia.

What the MRI findings mean for the surgical conversation

Reports can read like a foreign language, so here is how the common findings tend to steer the discussion. The table is a guide to the shape of the conversation, not a decision rule; your team will weigh age, overall health, how well medicines have worked, and your own priorities alongside the images.

What the scan shows	Likely classification	How it usually shapes the discussion
Artery or vein indenting or displacing the nerve on the painful side	Classical trigeminal neuralgia	Microvascular decompression is often discussed as a direct option; nerve-targeted procedures remain alternatives
Vessel touching the nerve without distortion	Classical or idiopathic, depending on the clinical picture	Teams differ; the pain story and response to medicines carry more weight
No vessel near the nerve, otherwise normal brain	Idiopathic trigeminal neuralgia	Surgery is not excluded; nerve-targeted procedures are often weighed first, and decompression remains possible for some
Bright plaque in the brainstem, often with other plaques	Secondary, due to multiple sclerosis	Neurology involvement; nerve-targeted procedures are typically favored over decompression
Mass lesion pressing on the nerve	Secondary, due to tumor or cyst	Plan centers on the lesion itself

Two points flow from this. A dramatic picture is helpful but not required: the Mayo Clinic and NHS both describe surgery as an option when medicines fail or cannot be tolerated, and that remains true for people whose scans look ordinary. And a dramatic picture is not a guarantee: a vessel can be lifted perfectly and pain can still persist or return, which is why no responsible team quotes outcomes from a scan.

Treat the report as the opening of a conversation. The right next step is to ask your surgeon to show you the images and explain, in their words, what they see and what it changes.

Who is usually offered surgery, and who is usually asked to wait

The ordering is consistent across guidance from NINDS, the NHS and the Mayo Clinic: medicines first, surgery when medicines stop working or cause more trouble than they prevent.

The first-line medicines are anticonvulsants, drugs originally developed for epilepsy that quiet overexcitable nerve fibers by stabilizing the electrical channels in their membranes. Carbamazepine is the most studied; related drugs are used when it is poorly tolerated. Whether a medicine works, and at what point side effects such as drowsiness, dizziness or unsteadiness outweigh benefit, is a judgment for the prescribing clinician, and nothing here should prompt anyone to start, stop or adjust a prescription.

Surgery usually enters the conversation when:

• attacks continue despite a properly tried medicine, or return after a period of control;
• side effects make daily life difficult, or blood tests show the medicine is affecting the liver, blood counts or sodium;
• the scan shows a clear vessel distorting the nerve and the person is medically fit for a general anesthetic;
• the pain is so severe that eating and drinking are compromised.

People often asked to wait include those whose pain has only recently started, since early attacks sometimes settle and the diagnosis may not yet be certain; those who have not yet had a fair trial of medicine; those whose pain pattern is atypical, because surgery tends to be less helpful when the pain is constant and burning rather than brief and electric; and those whose scan has raised a different question that needs answering first.

Age by itself is not a barrier. Health, frailty and the balance of risks are. Older adults or people with heart or lung conditions may be steered toward less invasive nerve-targeted procedures rather than an operation behind the ear, which is one more reason the scan and the medical assessment travel together.

How microvascular decompression uses the MRI in the operating room

Microvascular decompression is an operation performed under general anesthesia through a small opening in the skull behind the ear on the painful side. Working under a microscope, the surgeon follows the trigeminal nerve back to the brainstem, identifies the vessel resting on it, gently moves the vessel aside and places a small cushion of soft material between the two. The nerve itself is left intact. Johns Hopkins and the Mayo Clinic describe it as the procedure that addresses the presumed cause rather than the symptom, and NINDS notes it tends to offer the longest-lasting relief of the surgical options, with the trade-off of being the most invasive.

The MRI is on the wall, or on a screen, throughout. Before the operation it tells the surgeon which vessel to expect and on which side of the nerve, so the opening and the angle of approach can be planned. During the operation it is a reference when the real anatomy looks more crowded than expected; multiple small vessels are common, and the scan helps the surgeon decide which of them matched the pattern of distortion. Some teams build a three-dimensional reconstruction from the scan to rehearse the route.

The alternatives do not require a vessel to be found at all. Radiofrequency, glycerol and balloon procedures reach the nerve through a needle passed through the cheek and deliberately damage a portion of it, trading some facial numbness for pain control. Stereotactic radiosurgery focuses many beams of radiation on the nerve root without any incision, with effects that build over weeks. For these, the MRI serves a different purpose: it confirms the nerve is in a normal position and that nothing else is in the path.

Each option has its own risks, from hearing change and facial weakness with decompression to numbness and a rare, troublesome form of altered sensation with nerve-targeted methods. The NHS summarizes these candidly, and the discussion of which fits you belongs with your treating team.

What the days and weeks after the scan, and after surgery, usually look like

The timeline after the scan is mostly waiting and talking. The report typically reaches the referring team within days; the next appointment is where images, pain diary and medicine history are set side by side. Expect that conversation to take its time. Good surgical decisions in this condition are rarely urgent, and a second opinion is a normal request rather than a slight.

If microvascular decompression is chosen, the operation itself usually lasts a few hours. Johns Hopkins describes a short hospital stay, generally a few days, during which the team watches for headache, nausea, hearing change and wound problems. Most people are walking the next day. Soreness behind the ear and a stiff neck are common and fade over the following weeks.

Recovery at home is measured in weeks rather than days. Fatigue is the most common complaint. Driving, lifting and strenuous exercise are typically held back until the team clears them, and returning to desk work often happens within several weeks, with physical work taking longer; these are typical ranges described by Johns Hopkins, not promises for any individual. Pain medicines for the nerve are usually continued at first and then reviewed by the prescribing clinician as the picture becomes clear; some people are weaned, some are not, and that decision is never one to make alone.

Nerve-targeted procedures through the cheek are often done as day cases or with a single overnight stay, with recovery of a few days and the expected numbness noticeable from the start. Radiosurgery involves no recovery from an incision, but relief, if it comes, develops over weeks to months, which is why it is sometimes chosen when pain is manageable in the meantime.

Whatever the route, a follow-up scan is not routine after decompression unless something changes. The images from before the operation remain the reference, and new facial pain years later is evaluated afresh.

What people often get wrong about the MRI before trigeminal neuralgia surgery

Myths gather around this scan because the stakes are high and the report is terse. Here are the ones that cause the most confusion, corrected.

A normal MRI means it is not trigeminal neuralgia. False. The diagnosis is clinical. The Mayo Clinic and NINDS both describe imaging as a tool to look for causes, not a test that confirms or denies the condition. Idiopathic trigeminal neuralgia is a recognized category precisely because many scans look ordinary.

A vessel on the nerve proves the cause. Not quite. Contact between vessels and the trigeminal nerve is frequently seen in people without pain, and on the pain-free side of people who have it. A vessel that distorts or displaces the nerve is more convincing than one that merely touches it, and even then the match with the pain story is what makes the finding meaningful.

The scan tells you whether surgery will work. It cannot. Clear compression makes decompression a logical choice, but no imaging feature predicts an individual outcome, and no reputable team quotes a figure from a picture.

Surgery is only for people with a vessel on the scan. The NHS and Mayo Clinic describe surgery as an option when medicines fail, regardless of imaging. The scan influences which procedure, not whether one can be considered.

MRI involves radiation. It does not. The technology is a magnet and radio waves, and MedlinePlus notes it has no known radiation risk, which is why it can be repeated if needed.

Dental work must come first. Many people have teeth removed chasing the pain before the diagnosis is made. A dentist’s examination is reasonable when the pain is in the jaw, but tooth extraction does not help trigeminal neuralgia, and an unremarkable dental assessment is itself a clue pointing toward the nerve.

Questions to ask your care team

Walk in with questions written down. Attacks make conversation hard, and a list keeps the appointment from being steered by whichever worry arrived last. These are the ones that tend to unlock the most useful answers.

• Which category does my pain fall into on the scan: classical, secondary or idiopathic, and how confident are you in that?
• Can you show me the images and point to the nerve and the vessel you are describing?
• Is the vessel an artery or a vein, and does it distort the nerve or only touch it?
• Did the scan show anything else, however minor, and does it need following up?
• Does my pain pattern, brief and electric or more constant, change which procedure you would favor?
• What are the alternatives to the operation you are suggesting, and why do you rank them the way you do for me?
• What are the specific risks of this procedure for someone with my other health conditions?
• What would make you advise waiting rather than operating now?
• If pain comes back after surgery, what are the options then?
• Who manages my medicines before and after the procedure, and when will they be reviewed?
• What symptoms after surgery should prompt a call, and whom do I call?
• Would a second opinion from another neurosurgeon or a neurologist be reasonable, and can you help arrange it?

Notice that none of these ask the surgeon to promise anything. The best answers will contain uncertainty, because honest answers in this condition always do. A team that says “the scan suggests, but the operation will tell us” is being precise, not evasive.

Bring someone with you if you can. Two sets of ears catch more, and a companion can ask the question you had decided not to.

When to call your doctor

Most of the trigeminal neuralgia journey unfolds at the pace of scheduled appointments, but a few situations call for a same-day conversation with your treating team or urgent care.

Before any surgery, contact your doctor promptly if attacks have become so frequent that you cannot eat or drink enough and you feel lightheaded, are passing little urine or cannot keep medicines down; dehydration is a real risk in severe flares. Seek urgent assessment if the pain changes character into a constant, severe headache unlike anything before, if you develop new numbness, weakness or drooping of the face, double vision, trouble swallowing, hearing loss in one ear, or difficulty with balance. These are not features of uncomplicated trigeminal neuralgia and need evaluation. Call as well if a prescribed medicine produces a rash, fever, mouth ulcers, unusual bruising, marked confusion or severe unsteadiness, since anticonvulsants can rarely affect the skin, blood counts or sodium levels.

After surgery, call the surgical team the same day for fever, a wound that is red, swollen, leaking fluid or bleeding, clear fluid dripping from the nose or ear, a worsening headache that is worse when sitting up, a stiff neck with sensitivity to light, new facial weakness, sudden hearing loss, persistent vomiting, or a calf that is swollen, warm and painful, which can signal a blood clot. Chest pain, breathlessness, confusion or a seizure are emergencies; call emergency services rather than the clinic.

One quiet red flag deserves mention. If the pain stops responding to a medicine that previously controlled it, or if it spreads to the other side of the face, tell your team. Either can prompt a review of the diagnosis and sometimes a repeat scan.

Nothing in this article replaces that conversation. Every decision about scans, medicines and surgery sits with the clinicians who know your history and have seen your images.

Frequently asked questions

Can an MRI show trigeminal neuralgia?

Not directly. MRI cannot see pain, but it can show what may be causing it: a blood vessel pressing on the trigeminal nerve near the brainstem, a multiple sclerosis plaque, or a tumor. The diagnosis itself comes from the pattern of attacks and a neurological examination. A normal scan does not rule the condition out, and many people with typical trigeminal neuralgia have unremarkable imaging.

What is neurovascular compression on MRI, and does it always mean surgery?

Neurovascular compression means a vessel lies against a cranial nerve closely enough to irritate or deform it. On the scan, radiologists grade it from simple contact to visible indentation or displacement. It does not automatically mean surgery. Many people with such contact have no pain, and surgery is usually considered only when medicines have failed or cannot be tolerated, a judgment the treating team makes with you.

Why does the surgeon need a special MRI protocol instead of a standard brain scan?

The trigeminal nerve is only a few millimeters wide, so a standard brain MRI with thicker slices can miss a small vessel lying against it. Dedicated protocols use thin, high-resolution sequences that make the fluid around the brainstem bright, so the dark nerve and vessel stand out clearly. Some centers add magnetic resonance angiography to map arteries and veins without a catheter.

How is a microvascular decompression MRI used during the operation?

The scan is the surgeon’s map. Before the operation it shows which vessel is likely responsible, whether it is an artery or vein, and on which side of the nerve it sits, which guides the approach behind the ear. During surgery it serves as a reference when several small vessels are found. The surgeon’s direct view under the microscope still makes the final call about what to move and pad.

What is neuralgia, in plain terms?

Neuralgia is pain generated by a nerve itself rather than by injury to the tissue it supplies. The signal is faulty, not the structure being reported on. Trigeminal neuralgia involves the nerve that carries sensation from the face, producing brief electric attacks triggered by touch, chewing or cold air. Other neuralgias include postherpetic neuralgia after shingles and occipital neuralgia at the back of the head.

What could be causing pain on the right side of my face, jaw and ear?

Several conditions overlap in that area: dental problems, jaw joint dysfunction, sinus infection, ear infection, shingles, and trigeminal neuralgia. The pattern helps sort them. Brief electric shocks triggered by touch point toward the nerve; a constant ache worse with chewing points toward the joint or teeth; ear pain with hearing change points toward the ear. A clinician’s examination, and sometimes an MRI, is needed to tell them apart.

Will I need contrast dye for an MRI for trigeminal neuralgia?

Not always. Seeing a vessel on the nerve does not require contrast, because the thin-slice sequences rely on the natural contrast between bright fluid and dark nerve. Gadolinium contrast is added when the team wants to look carefully for tumors, inflammation or multiple sclerosis plaques. If contrast is planned, kidney function may be checked beforehand, and you should mention any previous reaction to dye.

Can I have surgery if my MRI is normal?

Yes, in many cases. Guidance from the NHS and the Mayo Clinic describes surgery as an option when medicines fail or cause intolerable side effects, regardless of imaging. A normal scan tends to shift the discussion toward nerve-targeted procedures, though some surgeons still offer decompression because small veins can be missed on MRI. The right choice depends on your pain pattern, health and priorities, decided with your team.

What if the scan shows a vessel on the side that does not hurt?

This is common and usually not concerning. Contact between a vessel and the trigeminal nerve is frequently seen in people with no facial pain at all, and the opposite side of someone with trigeminal neuralgia is no exception. Surgeons focus on the painful side and on whether the vessel there distorts the nerve. A finding on the pain-free side is noted but does not by itself change the plan.

Does trigeminal neuralgia surgery need to happen quickly after the MRI?

Rarely. Trigeminal neuralgia is intensely painful but not life-threatening, and the scan findings are generally stable over months, so there is time to weigh options, try or adjust medicines under the prescribing clinician’s guidance, and seek a second opinion. The exceptions are when the scan reveals a tumor or another lesion that needs its own timeline, or when severe attacks are preventing eating and drinking.
