Testicular Pain in Men: Causes, Diagnosis & When to Seek Urgent Care

Testicular pain is discomfort in or around one or both testicles. It may originate from the testicle itself or from nearby structures — the epididymis, spermatic cord, scrotal tissues, groin, prostate, urinary tract, or abdomen/lower back — meaning it can sometimes be referred pain.

The pain may be sharp, dull, aching, throbbing, burning, heavy, constant, or intermittent, and may occur with swelling, redness, urinary symptoms, nausea, fever, or a change in the position or appearance of the testicle.

Acute pain develops suddenly or over a short period. Sudden testicular pain should be taken seriously, since conditions such as testicular torsion can damage the testicle if treatment is delayed.

Chronic pain persists or repeatedly returns over an extended period. Possible causes include varicocele, chronic epididymal inflammation, chronic prostatitis/chronic pelvic pain syndrome, nerve-related pain, pelvic floor dysfunction, and previous surgery or trauma. Persistent or recurrent pain should be evaluated rather than repeatedly treated with pain medication alone.

Testicular torsion occurs when the spermatic cord twists and cuts off the testicle’s blood supply. It typically causes sudden, severe pain usually on one side, rapidly developing scrotal swelling, nausea or vomiting, and a testicle that may sit higher than usual or appear abnormally positioned.

This is a urological emergency — the chance of saving the testicle decreases the longer blood flow is interrupted. EAU guidance emphasizes urgent surgical evaluation, ideally within the first few hours after symptom onset. Do not wait for severe testicular pain to disappear on its own if torsion is possible — intermittent torsion can also occur, with pain resolving before returning later.

• Epididymitis — inflammation of the epididymis, often from infection; pain develops gradually with possible swelling, burning urination, frequent/urgent urination, penile discharge, and fever
• Orchitis — inflammation of the testicle itself, sometimes occurring with epididymitis (epididymo-orchitis)
• Varicocele — enlargement of the veins around the testicle; often asymptomatic but can cause dull pain that worsens after standing and improves lying down
• Hydrocele — fluid accumulation around the testicle, more often causing swelling than pain
• Inguinal hernia — tissue pushing through a weakened area in the groin, with pain worsening when coughing, lifting, or straining
• Testicular trauma — bruising, swelling, hematoma, or in serious cases, rupture
• Kidney stones — referred pain from the flank or back toward the groin and testicle, often with nausea and blood in the urine
• Prostatitis — inflammation related to the prostate, which can cause pain in the scrotum, penis, perineum, lower abdomen, or lower back
• Spermatocele — a fluid-filled cyst near the epididymis, usually painless
• Other causes — nerve-related pain, pelvic floor dysfunction, post-surgical pain, ureteral obstruction, and referred pain from the spine, hip, or abdomen

How the pain begins offers important clues:

• Sudden, severe pain → testicular torsion, significant trauma
• Gradually worsening pain → epididymitis, orchitis, inflammation
• Dull, dragging pain → varicocele, large hydrocele
• Pain with a groin bulge → inguinal hernia
• Pain with burning urination → epididymitis, prostatitis, UTI
• Flank pain spreading to the testicle → kidney stone
• Recurrent pelvic/scrotal discomfort → chronic prostatitis/pelvic pain, nerve-related pain

These patterns aren’t diagnostic on their own — testicular torsion can occasionally present atypically, and imaging or urgent surgical assessment may be necessary when clinical suspicion is high.

Seek emergency medical care immediately for:

• Sudden or severe testicular pain
• Sudden pain accompanied by nausea or vomiting
• Rapid scrotal swelling
• A testicle that appears higher or unusually positioned
• Severe pain after significant trauma
• Severe pain with abdominal pain
• Severe pain with fever or feeling seriously ill

The most important thing is recognizing testicular torsion in time: because it cuts off blood supply, delayed treatment can result in permanent damage or loss of the testicle. Even if the pain resolves on its own, repeated sudden episodes should still be evaluated — intermittent torsion is possible.

A doctor usually begins with a detailed medical history (when the pain began, sudden or gradual onset, one or both sides, trauma, fever, nausea, burning urination, discharge, STI risk factors) and a physical examination of the abdomen, groin, penis, scrotum, testicles, epididymis, and spermatic cord.

Depending on the suspected cause, testing may include urinalysis, urine culture, STI testing, and blood tests — a normal urine test does not exclude every possible cause. A scrotal ultrasound with Doppler is commonly used for suspected acute scrotal conditions, evaluating blood flow, epididymitis, varicocele, hydrocele, masses, and trauma. However, ultrasound isn’t perfect: blood flow may occasionally appear preserved in early, partial, or intermittent torsion, so a reassuring ultrasound should not override strong clinical suspicion or delay urgent treatment.

• Testicular torsion — urgent surgery to untwist the spermatic cord and fix the testicle in place (the opposite testicle is commonly fixed too, to prevent future torsion)
• Epididymitis/orchitis — antibiotics for bacterial infection, plus pain management, rest, and scrotal support; antibiotics are not used automatically for every case
• Varicocele — mild discomfort may be managed conservatively; treatment is considered for persistent pain, testicular effects, or fertility concerns
• Hydrocele — small asymptomatic hydroceles may simply be monitored; large or symptomatic ones may require surgery
• Inguinal hernia — treatment depends on size and symptoms; complicated hernias may require surgical repair
• Kidney stones — treatment depends on stone size, location, and complications
• Chronic pain — management may involve medications, physical therapy, behavioral approaches, or nerve-directed treatments depending on the cause

For mild, non-urgent discomfort, avoid activities that worsen the pain, wear supportive underwear, use appropriate over-the-counter pain medication, and avoid repeated pressure on the scrotum — but these measures should never delay emergency evaluation for sudden or severe pain. Do not attempt to diagnose testicular torsion at home.

Not every cause can be prevented, but some measures help: wearing protective equipment during contact sports, practicing safer sex, treating urinary or STI symptoms promptly, avoiding unnecessary trauma to the testicles, and seeking care for persistent or recurring scrotal symptoms.

Does testicular pain mean cancer? Usually not — testicular cancer more commonly presents as a painless lump or a change in size or shape, though any new lump should still be evaluated. Does testicular pain always need an ultrasound? Not every case — only when clinically indicated. Can testicular pain go away on its own? Sometimes, depending on the cause, but sudden severe pain or recurring episodes should always be evaluated by a doctor.
