When Epididymitis Is Not Improving: Abscess, Chronic Pain and the Follow-Up Your Doctor Plans

The antibiotics ran out on Sunday. By Tuesday the ache behind his left testicle had not gone anywhere, the swelling felt firmer than before, and the thermometer he had put back in the drawer came out again. He had done everything the leaflet said. So why was this still happening?

That question sits at the heart of most searches about epididymitis complications. The majority of people with an inflamed epididymis get better with a standard course of treatment, and quickly. A smaller group do not, and they are the ones left wondering whether something has been missed, whether pus is collecting, or whether this is the start of pain that never fully leaves.

This explainer walks through what happens when the usual timeline slips: the abscess a clinician checks for, the emergencies that can masquerade as infection, the six-week line that defines chronic epididymitis, and the follow-up plan a careful doctor builds around each of them.

What actually happens inside the epididymis when it is not improving

The epididymis is a tightly coiled tube that sits along the back of each testicle, storing sperm and moving it toward the vas deferens. In acute epididymitis, bacteria or another irritant inflame that tube, fluid floods the tissue, and the whole structure swells until it can feel like a second, tender lump behind the testicle.

Antibiotics work on the bacteria. They do not directly shrink the swelling. Repair of inflamed tissue lags behind bacterial clearance, which is why soreness and firmness usually outlast the fever by days or weeks. Slow but steady improvement is therefore normal. What is not normal is a flat line, or a climb.

When epididymitis is genuinely not improving, clinicians think in four directions at once. First, the drug may not match the organism, either because a resistant strain is involved or because the initial guess about the likely bacteria was wrong. Second, pus may have walled itself off into a pocket that antibiotics cannot reach well, because pus has no blood supply of its own. Third, the inflammation may have spread from the epididymis into the testicle, a condition called epididymo-orchitis, which is slower to settle. Fourth, and most importantly, the problem may never have been infection at all: a twisted testicle, a tumor, a reflux of urine into the tube, or a rare inflammatory disease can each produce a swollen, painful scrotum that fails every antibiotic sent its way.

Each of those explanations calls for a different response, and none of them is answered by simply extending the same prescription. That is why guidelines treat “not improving” as a signal to re-examine, rather than a reason to wait longer.

What is epididymitis caused by, and why the cause shapes the follow-up

The answer changes with age and circumstance, and that matters because the follow-up plan follows the cause.

In sexually active men under about 35, the CDC identifies chlamydia and gonorrhea as the most common culprits. In men who practice insertive anal sex, and in most men over 35, the usual sources are gut bacteria such as Escherichia coli that travel from the urinary tract, often when urine flow is obstructed by an enlarged prostate, a catheter or a recent urological procedure. Viral causes exist too; the mumps virus can inflame the testicle and epididymis in people who were not vaccinated. Tuberculosis and fungal infections are rare but recognized causes of stubborn, slow-growing epididymal swelling.

Not every case is infectious. Mayo Clinic lists urine flowing backward into the epididymis during heavy lifting or straining as a cause, and notes that the heart rhythm medicine amiodarone can inflame the epididymis as a side effect. Autoimmune conditions that inflame blood vessels, collectively called vasculitis, occasionally present in the scrotum. In boys and adolescents, viral illness, urine reflux and torsion of a small vestigial structure on the testicle are more common than sexually transmitted infection.

Why does this matter for someone who is not getting better? Because a sexually transmitted cause means partners need testing and treatment, and reinfection is a real reason symptoms return. An enteric cause in an older man points toward the bladder and prostate, so the follow-up includes checking how well the bladder empties. A non-infectious cause means more antibiotics will do nothing, and the search has to move elsewhere. Getting the cause right is the first task of the re-evaluation, and it often means repeating tests that were skipped or unavailable at the first visit.

How long should epididymitis take to improve?

Guidelines give a surprisingly specific early checkpoint. The CDC advises that symptoms should begin to improve within 48 to 72 hours of starting appropriate treatment, and that failure to improve in that window requires reassessment of both the diagnosis and the therapy. That does not mean the pain should be gone in three days. It means the direction of travel should have changed: fever easing, pain slightly less, swelling no longer growing.

Full resolution is slower. Cleveland Clinic notes that it can take up to about four weeks for symptoms to disappear completely, and a firm, slightly tender area on the epididymis can persist for weeks beyond that as inflamed tissue remodels. Improvement usually follows a predictable order: temperature and general unwellness settle first, sharp pain gives way to an ache, and the hardness is the last thing to fade.

So what counts as “not improving”? Clinicians look for any of the following after the first three days of treatment, or at any time if the change is abrupt:

• Pain that is worse rather than better, or that has become throbbing.
• Fever returning after it had settled, or chills.
• Swelling that is visibly larger, or skin that is red, shiny and tight.
• A soft, fluid-feeling area within a previously firm swelling.
• New nausea, vomiting or feeling faint.

The CDC adds a second checkpoint: swelling and tenderness that persist after the antibiotic course has been completed should prompt a comprehensive evaluation for alternative diagnoses, including tumor, abscess, infarction, tuberculosis and fungal infection. In practice that usually means a scrotal ultrasound and a fresh set of urine and blood tests, arranged by the treating team rather than assumed to be unnecessary.

Epididymitis complications: what can happen if it is left untreated

Most people who are treated promptly never see any of the complications below, and the NHS describes epididymitis as a condition that usually gets better with treatment. The list matters because it explains what the re-evaluation is looking for, not because it predicts an individual outcome.

Scrotal abscess. Mayo Clinic identifies a pus-filled infection in the scrotum as a key complication. Bacteria multiply faster than the immune system can clear them, and the body walls off the mess into a pocket that antibiotics penetrate poorly. The next section covers how it is found and drained.

Epididymo-orchitis. Inflammation that spreads from the epididymis into the testicle itself. The testicle becomes enlarged and exquisitely tender, and recovery takes longer.

Reactive hydrocele. A collection of clear fluid around the testicle, produced by the irritated lining of the scrotum. It is usually harmless and drains away as inflammation settles, but it can make the scrotum feel alarmingly large.

Testicular infarction. The testicle sits inside a tough fibrous coat. Severe swelling inside that coat can compress its blood vessels enough to starve the tissue, which is one reason ultrasound with Doppler (a technique that shows blood flow) is used when things are not settling.

Chronic pain. Discomfort persisting beyond six weeks, discussed below, is the most common long-term consequence and can occur even after successful treatment of the infection.

Reduced fertility. Mayo Clinic lists this as a rare complication. Scarring can block the tube on one side, and infection of both sides is more consequential than one.

Very rarely, an untreated abscess can break through the scrotal skin or trigger a body-wide infection. Untreated sexually transmitted epididymitis also keeps the infection circulating to partners. None of these are reasons for panic; they are the reasons a doctor does not shrug at a scrotum that refuses to improve.

Scrotal abscess: how it is found and how it is drained

An abscess is a closed pocket of pus, dead tissue and bacteria. It behaves differently from ordinary inflammation because the pocket has no blood flow, so antibiotics carried in the blood cannot reach its center in useful amounts. Clinicians suspect one when a person on treatment develops a second wave of fever, a throbbing rather than aching pain, tense red skin over one part of the scrotum, or an area that feels soft and fluid under the finger where everything else is firm.

The test is a scrotal ultrasound. Sound waves cannot pass through pus the way they pass through solid inflamed tissue, so an abscess shows as a dark, fluid-filled space, often with floating debris and no blood flow inside it on Doppler. The same scan checks the testicle’s blood supply and looks for a solid mass, which is why it is ordered so readily once the expected improvement has stalled.

Draining is the treatment principle. Depending on size and location, a urologist may aspirate the pocket with a needle guided by ultrasound, or open and drain it in an operating room, sometimes leaving a small drain or dressing in place for a few days. Fluid from the abscess is sent for culture, which finally identifies the organism and lets the team choose an antibiotic that fits rather than one that was guessed. If imaging or surgery shows that the testicle’s tissue has died, removal of the testicle (orchiectomy) may be recommended; this is a decision the surgeon discusses in advance wherever possible, weighing the risk of leaving dead tissue behind.

Recovery after drainage involves wound checks, completing whatever antibiotic course the team sets, scrotal support and a follow-up scan or examination to confirm the pocket has not refilled. People often ask whether the other testicle is at risk. An abscess is usually one-sided, and the scan will have looked at both.

Chronic epididymitis: the six-week line and its three patterns

The CDC draws the boundary at six weeks. Discomfort or pain in the scrotum, testicle or epididymis lasting that long, with or without swelling, is classified as chronic epididymitis. It is not simply “acute epididymitis that lasted a long time”; it is a different clinical problem with its own evaluation.

Guidelines describe three patterns, and the distinction guides what is offered.

Inflammatory chronic epididymitis involves ongoing pain with detectable swelling from infection or non-infectious inflammation. Granulomatous conditions such as tuberculosis belong here, as do some autoimmune causes. This is the group where further tests of the urine, blood and sometimes tissue are most likely to change management.

Obstructive chronic epididymitis arises when the tube is blocked, most often after a vasectomy or from scarring left by an earlier infection. Sperm and fluid back up behind the blockage, stretching the epididymis. The pain tends to be a persistent dull ache made worse by ejaculation or physical strain.

Chronic epididymalgia is pain in the epididymis with no swelling, no infection and no blockage that tests can find. It is the most common and the most frustrating pattern, and it overlaps considerably with chronic pelvic pain syndrome, a term for persistent pelvic or genital pain without a demonstrable cause.

Management across all three starts with what is safe and reversible: anti-inflammatory pain relievers as a class, supportive underwear, warmth, avoiding activities that reproduce the pain, and time. Where nerve-type pain is suspected, medicines developed for neuropathic pain may be considered. Local anesthetic nerve blocks can both relieve pain and help identify whether the pain is truly coming from the scrotum. Surgery, discussed later, is a last resort with genuinely uncertain results. Repeated antibiotic courses for pain without evidence of infection are not supported by evidence and carry their own harms.

Can chronic epididymitis affect the pelvic floor?

It can, and the connection runs in both directions. The pelvic floor is the hammock of muscle that supports the bladder, bowel and, in men, the base of the penis and the structures leading to the scrotum. When something in the groin hurts for weeks, the body’s reflex is to guard: muscles around the painful area tighten and stay tight. Over time that tension becomes a source of pain in itself, felt as a deep ache in the perineum (the area between scrotum and anus), pressure in the rectum, a sense of incomplete bladder emptying, or pain after sitting.

Shared nerves explain why the two areas blur together. The nerves supplying the epididymis and scrotum also carry sensation from the lower abdomen, inner thigh and perineum, and the pudendal nerve, which serves the pelvic floor, runs close by. Irritation in one territory can be felt in another, which is why some people with chronic epididymitis describe pain that seems to move, or that is worse with bowel movements or long car journeys.

What does the evidence say? Honestly, less than patients deserve. Pelvic floor involvement is well described in chronic pelvic pain syndrome generally, and specialist pelvic physiotherapy (manual release of tight muscles, stretching, breathing and relaxation training) is a recognized option within that broader framework. Studies specific to chronic epididymal pain are small. That is not a reason to dismiss it; it is a reason to describe it accurately. A clinician who finds tender, tight pelvic floor muscles on examination has found something treatable that antibiotics were never going to touch.

People often ask whether pelvic floor exercises will help. Strengthening exercises can worsen pain in a floor that is already over-tight, so the usual advice is assessment by a physiotherapist trained in pelvic pain before starting any routine, rather than online exercise programs.

Who is usually offered a procedure, and who is asked to wait

Most epididymitis never reaches an operating room. Procedures are reserved for specific findings, and the criteria are fairly consistent across guidelines.

Usually offered drainage or surgery:

• A confirmed abscess on ultrasound, especially with fever, spreading redness or a fluid-feeling swelling.
• Signs that the testicle’s blood supply is compromised, or suspicion of torsion at any point.
• Ultrasound showing a solid mass that could be a tumor, which requires surgical assessment regardless of infection.
• Tissue confirmed to be non-viable, where removal prevents ongoing infection.
• Rarely, a chronic obstructive picture after vasectomy where conservative measures have failed over many months.

Usually asked to wait, with follow-up:

• Uncomplicated epididymitis that is improving, even slowly, on treatment.
• A firm lump remaining after infection that is shrinking and shows no worrying features on scan.
• A reactive hydrocele that is not causing pressure symptoms.
• Chronic pain in its first months, where conservative approaches have not yet been tried.

The hardest conversations concern surgery for chronic pain without infection. Options include removing the epididymis (epididymectomy) or cutting the nerves running along the spermatic cord (microsurgical denervation). Both are performed, and both help some people. The evidence, however, comes from small case series rather than controlled trials, and a meaningful share of people report unchanged or occasionally worse pain afterward. Guidelines therefore place surgery after a full trial of conservative care, after other causes have been excluded, and after an honest discussion of uncertain benefit. Some surgeons use a diagnostic nerve block first: if numbing the cord temporarily abolishes the pain, surgery on that pathway is more likely to be relevant. Whether any of this is appropriate for a particular person is a judgment for the treating urologist, made with the person, not for them.

Acute, complicated and chronic epididymitis compared

Seeing the three situations side by side clarifies why the follow-up plan looks so different depending on which one applies. The timelines below are the typical ranges described by the CDC and Cleveland Clinic, not guarantees for any individual.

Feature	Acute, uncomplicated	Acute, complicated	Chronic
Definition	Pain and swelling under 6 weeks, responding to treatment	Abscess, epididymo-orchitis, infarction or torsion suspected	Pain lasting 6 weeks or more (CDC)
Typical clue	Gradual onset, improving within 48–72 hours of therapy	No improvement by 72 hours, returning fever, fluctuant swelling, sudden severe pain	Persistent ache, often without fever or swelling
Key test	Urine tests, STI testing	Urgent scrotal ultrasound with Doppler; cultures	Ultrasound to exclude tumor; targeted infection tests
Usual approach	Antibiotic course chosen by likely cause; support, rest	Drainage of abscess, surgery if torsion or dead tissue, antibiotic adjusted to culture	Conservative pain management, physiotherapy, nerve blocks; surgery only as last resort
Typical timeline	Improvement within days; full resolution up to about 4 weeks	Depends on procedure; wound and scan follow-up over weeks	Months; reassessed at intervals set by the team
Follow-up focus	Partner treatment if STI; retest; urinary assessment if older	Confirm abscess resolved; check testicle viability	Pain control, function, ruling out missed diagnoses

Two points stand out. The complicated column is defined largely by time: the clock starts when treatment begins, and a failure to turn the corner by day three moves a person from the first column to the second until proven otherwise. The chronic column is defined by the absence of the features that make the second column urgent, which is why a person with long-standing pain is examined carefully, but usually not rushed.

What the follow-up your doctor plans usually involves

A good follow-up plan is built around the cause, so it starts by confirming what that cause was.

The 72-hour check. The CDC recommends re-evaluation if there is no improvement within 72 hours of starting therapy. This may be a phone call or a visit, but it is a genuine checkpoint, not a formality. If the direction is right, the plan continues. If not, the diagnosis is reopened.

Imaging when swelling persists. Swelling or tenderness that outlasts the antibiotic course triggers the comprehensive evaluation described earlier: ultrasound, repeat urine and blood tests, and in some cases tests for tuberculosis or fungal infection. A residual lump that is shrinking may simply be watched with a repeat scan on a schedule the team sets.

Partner care when the cause is sexually transmitted. The CDC advises that all sexual partners within the 60 days before symptom onset should be evaluated and treated, and that people should abstain from sexual intercourse until they and their partners have completed treatment and symptoms have resolved. Because reinfection is common, retesting some months after treatment is also recommended. Skipping this step is one of the most avoidable reasons epididymitis “comes back”.

Urinary assessment when the cause is enteric. In older men, the follow-up often includes checking how completely the bladder empties, examining the prostate and asking about urinary symptoms that predated the infection. Treating the reason bacteria reached the epididymis prevents the next episode.

Referral. Urology involvement is usual for abscess, suspected tumor, recurrent episodes and any pain crossing the six-week line. For chronic pain, the team may broaden to include a pain specialist or pelvic physiotherapist.

Every one of these steps is decided by the treating clinician in light of the individual’s findings. The value of knowing the outline is that it lets a person ask, at the right moment, which of these apply to them.

What the following weeks usually look like when epididymitis is slow to settle

Timelines below draw on the CDC and Cleveland Clinic descriptions of typical recovery and are ranges, not promises.

Days 1 to 3. The first sign of improvement is usually general: less feverish, less shivery, appetite returning. Pain relief at this stage comes from rest, lying down with the scrotum elevated on a folded towel, supportive underwear and cool packs wrapped in cloth for short periods. This is also the window in which a lack of improvement should be reported.

Days 4 to 14. Sharp pain softens into an ache. Swelling starts to recede, although the epididymis often still feels enlarged and firm. Most people return to desk work and light activity here. Heavy lifting and vigorous exercise tend to aggravate the ache and are commonly deferred. If the cause was sexually transmitted, this is the period for partner treatment and continued abstinence.

Weeks 2 to 4. Cleveland Clinic notes complete resolution can take up to about four weeks. A small, non-tender or minimally tender firmness may remain longer; this is scar tissue and is usually watched rather than treated. Anyone who had an abscess drained is having wound checks and possibly a repeat scan in this period.

Week 6. The line. If pain is still present and interfering with life, the condition is now classified as chronic epididymitis and the plan changes from “wait for the infection to settle” to “assess and manage persistent pain”. That shift is not a failure; it is the point at which a different set of tools becomes appropriate.

Emotionally, the slow phase is often the hardest. Pain in this part of the body carries worry about fertility, sexual function and cancer that people rarely voice. Naming those worries at a follow-up visit gives the team a chance to address them with the scan and test results in hand.

What people often get wrong about epididymitis complications

“If the antibiotics did not work, I need stronger antibiotics.” Sometimes. Just as often, the problem is a wrong diagnosis, an abscess that needs draining, or inflammation that was never bacterial. Guidelines ask for re-evaluation, not escalation.

“A lump left behind means cancer.” A firm epididymis after infection is usually scar tissue, and it shrinks over weeks. But the CDC does list tumor among the diagnoses to consider when swelling persists, which is exactly why an ultrasound is arranged rather than assumed away. The scan distinguishes the two.

“Chronic epididymitis means the infection is still there.” In most chronic cases no infection can be found, and repeated antibiotic courses do not help. The pain has become a problem of nerves, muscles and scar tissue, and it is managed accordingly.

“Surgery will take the pain away.” For abscess and torsion, surgery addresses the cause. For chronic pain without a structural cause, the evidence for epididymectomy and denervation comes from small series with mixed results, and some people report no change or worsening. It is a considered last step.

“Epididymitis always comes from a sexually transmitted infection.” In men over 35 and in those with urinary problems or catheters, gut bacteria from the urinary tract are the usual source. Viral, medication-related and autoimmune causes exist too.

“Untreated epididymitis makes you infertile.” Mayo Clinic classes reduced fertility as a rare complication. One-sided scarring leaves the other side working; two-sided or repeated infection is the greater concern.

“Sudden severe scrotal pain can be slept on.” Testicular torsion, where the testicle twists and cuts off its blood supply, is a surgical emergency. Mayo Clinic notes the testicle can usually be saved if treated within about four to six hours. It is the one scenario in this article where waiting for a morning appointment is the wrong call.

Questions to ask your care team

People often leave appointments having forgotten the question that kept them awake. These are worth writing down beforehand; none of them is presumptuous, and a good team will welcome them.

• What do you think caused my epididymitis, and how sure are we? Have the urine and STI tests come back?
• By what day should I expect to feel better, and what exactly should I do if I do not?
• Do I need an ultrasound now, or only if the swelling has not gone by the end of treatment?
• Did the scan check blood flow to the testicle and look for a mass, as well as for an abscess?
• If an abscess is found, what are the options for draining it, and what would make you recommend removing the testicle?
• If the cause was sexually transmitted, who needs to be tested and treated, and when can we safely resume sex?
• Should I be retested for reinfection, and when?
• Is there anything about my bladder or prostate that made this more likely, and does that need looking at?
• Could any of my regular medicines be contributing?
• If the pain lasts beyond six weeks, who will manage it, and what would the plan look like?
• Is pelvic floor physiotherapy something you would consider for me, and how would I access it?
• What is the evidence for and against surgery for chronic pain in my situation?
• Which symptoms should make me call you today rather than wait for the next appointment?

Two further questions rarely get asked and often matter most. First: “What are you most worried about ruling out?” It tells you what the tests are actually for. Second: “What would make you change the plan?” It turns follow-up from a passive wait into something you can monitor yourself, with the team’s thresholds rather than your own guesses.

When to call your doctor

Most people recovering from epididymitis need nothing more than the follow-up already scheduled. A short list of signs, however, should prompt a same-day call, and a shorter list should send you straight to emergency care.

Go to an emergency department now if you have:

• Sudden, severe pain in one testicle, especially if it began within minutes, is accompanied by nausea or vomiting, or the testicle sits higher or at an odd angle. Testicular torsion is time-critical, and Mayo Clinic notes the best chance of saving the testicle is within about four to six hours.
• High fever with shaking chills, confusion, a racing heart or feeling faint, which can signal infection spreading into the bloodstream.
• Rapidly spreading redness, dark or blistered skin on the scrotum, or a crackling feel under the skin.
• Inability to pass urine.

Call your doctor the same day if:

• Pain or swelling is no better, or is worse, after 72 hours of treatment.
• Fever returns after settling, or the pain changes to a throbbing quality.
• A soft, fluid-feeling area has appeared within the swelling, or the skin over it is red and tight.
• Swelling, a lump or tenderness is still present after the antibiotic course has finished.
• You develop a discharge, blood in the urine or semen, or new pain in the lower back or abdomen.
• Pain has lasted six weeks or more, whether or not it is severe.

A message for the person who is unsure whether a symptom “counts”: describe it and let the team decide. Clinicians would far rather hear about a swelling that turns out to be a settling hydrocele than miss an abscess or a twisted testicle because someone did not want to bother them. The follow-up plan exists precisely so that these calls are expected, not exceptional, and every decision about what happens next rests with the treating team.

Frequently asked questions

Can chronic epididymitis be treated and controlled for good?

Many people reach a point where chronic epididymitis no longer limits daily life, but it is managed rather than eliminated in a single step. Treatment targets whichever mechanism is driving the pain: residual inflammation, an obstructed tube, tight pelvic floor muscles or irritated nerves. Conservative options come first, with nerve blocks and, rarely, surgery considered later. Outcomes vary between people, and the evidence for surgery is limited to small studies.

What is epididymitis caused by?

In sexually active men under about 35, the CDC identifies chlamydia and gonorrhea as the most common causes. In men over 35 and those with urinary obstruction, catheters or recent procedures, gut bacteria from the urinary tract are more typical. Viruses such as mumps, tuberculosis, urine reflux during straining, certain medicines and rare autoimmune conditions can also inflame the epididymis, which is why cause-specific testing matters.

What can happen if epididymitis is left untreated?

Untreated epididymitis can progress to an abscess, spread into the testicle as epididymo-orchitis, produce a fluid collection called a hydrocele, or, in severe cases, compromise the testicle’s blood supply. Mayo Clinic lists reduced fertility as a rare complication. Chronic pain lasting beyond six weeks can develop, and a sexually transmitted cause continues to spread to partners. Prompt treatment prevents most of these outcomes.

Can chronic epididymitis affect the pelvic floor?

Yes. Weeks of groin pain commonly cause the pelvic floor muscles to tighten protectively, and that tension can become a pain source in its own right, felt in the perineum, rectum or with prolonged sitting. Shared nerves link the scrotum and pelvic floor. Assessment by a physiotherapist trained in pelvic pain is a recognized option; strengthening exercises can worsen an over-tight floor, so evaluation should come before any routine.

What does it mean if my epididymitis is not getting better on antibiotics?

It usually means one of four things: the antibiotic does not match the organism, pus has collected into an abscess, inflammation has spread to the testicle, or the cause was never infection. The CDC recommends re-evaluation if there is no improvement within 72 hours. Expect a scrotal ultrasound with Doppler and repeat tests rather than simply a longer course of the same medicine.

How is a scrotal abscess drained?

A urologist may aspirate the pus with a needle guided by ultrasound or open and drain the pocket surgically, sometimes leaving a small drain for a few days. Fluid is sent for culture so the antibiotic can be matched to the organism. If the testicle’s tissue is found to be non-viable, removal may be recommended. Follow-up examination or scanning confirms the pocket has not refilled.

Is a lump left after epididymitis dangerous?

Usually not. A firm area on the epididymis after infection is most often scar tissue and shrinks over weeks. Because the CDC lists tumor among the diagnoses to consider when swelling persists past the end of treatment, a scrotal ultrasound is the standard way to tell scar from anything more concerning. A lump that grows, hardens or becomes painful should be reported promptly.

How do doctors tell epididymitis from testicular torsion when it is not improving?

Torsion typically begins suddenly and severely, often with nausea, and the testicle may sit high or at an odd angle, whereas epididymitis tends to build over a day or two. Ultrasound with Doppler shows whether blood is flowing to the testicle. Because Mayo Clinic notes the testicle can usually be saved within about four to six hours, sudden severe pain is treated as an emergency until torsion is excluded.

Should my partner be treated if I have epididymitis?

If the cause is a sexually transmitted infection, yes. The CDC advises evaluating and treating all sexual partners from the 60 days before symptoms began, abstaining from sex until both you and your partners have completed treatment and symptoms have resolved, and retesting some months later because reinfection is common. If the cause is gut bacteria from the urinary tract, partner treatment is not usually needed.

When is surgery considered for chronic epididymitis treatment?

Surgery such as epididymectomy or microsurgical denervation of the spermatic cord is generally considered only after conservative measures have been tried for months, other causes have been excluded by imaging and tests, and the person understands that results are uncertain. Evidence comes from small case series; some people improve and others report unchanged or worse pain. A diagnostic nerve block is sometimes used first. The decision rests with the treating urologist and the person together.
