Scrotal Pain? Why It’s Epididymitis & Medically Approved Next Steps

Epididymitis is a common, treatable cause of scrotal pain, usually from infection, that often starts gradually with one-sided pain, swelling, warmth, and sometimes urinary symptoms; doctors confirm it with an exam, urine and STI tests, and often an ultrasound, then treat with antibiotics plus rest, scrotal elevation, ice, and anti-inflammatories.

There are several factors to consider. See below for urgent red flags like sudden severe pain that may signal testicular torsion, how fast to seek care, recovery timelines, complications if untreated, partner management, and step by step next actions tailored to your situation.

Scrotal Pain? Why It's Epididymitis & Medically Approved Next Steps

Scrotal pain can be uncomfortable, alarming, and hard to ignore. One of the most common medical causes of scrotal pain in men is epididymitis — an inflammation of the epididymis, the coiled tube at the back of each testicle that stores and carries sperm.

The good news? Epididymitis is treatable, especially when diagnosed early. Here's what you need to know about why it happens, how to recognize it, and what medically approved next steps look like.


What Is Epididymitis?

The epididymis is a small, tightly coiled tube attached to the back of each testicle. When it becomes inflamed, the condition is called epididymitis.

Epididymitis can affect:

  • Sexually active men (especially under 35)
  • Older men (often due to urinary tract issues)
  • Men who recently had urinary procedures
  • Those with untreated infections

It may develop suddenly (acute epididymitis) or gradually (chronic epididymitis lasting more than 6 weeks).


Why Does Epididymitis Cause Scrotal Pain?

Inflammation causes swelling. When the epididymis swells, it presses against surrounding tissues in the scrotum, leading to:

  • Tenderness
  • Warmth
  • Redness
  • Aching or sharp pain

Pain may start gradually and worsen over hours or days. In some cases, it begins suddenly and becomes intense.

Unlike minor irritation, epididymitis pain usually doesn't go away on its own without treatment.


Common Causes of Epididymitis

Epididymitis is most often caused by infection.

In younger, sexually active men:

  • Sexually transmitted infections (STIs), especially:
    • Chlamydia
    • Gonorrhea

In older men:

  • Urinary tract infections (UTIs)
  • Prostate infections
  • Bladder outlet obstruction
  • Enlarged prostate

Other possible causes:

  • Recent catheter use
  • Recent urological procedures
  • Heavy lifting or straining (rare cases)
  • Viral infections (less common)

Understanding the cause is important because treatment depends on it.


Symptoms of Epididymitis

Symptoms can range from mild discomfort to significant pain.

Most common symptoms:

  • One-sided scrotal pain
  • Swelling in one testicle
  • Tenderness when touched
  • Feeling of heaviness in the scrotum
  • Warm or red skin over the area

Other possible symptoms:

  • Pain during urination
  • Frequent urination
  • Burning sensation when urinating
  • Discharge from the penis
  • Fever or chills (in more severe cases)
  • Pain during ejaculation

If symptoms develop over several days and gradually worsen, epididymitis becomes more likely.


Important: Could It Be Something More Serious?

Not all scrotal pain is epididymitis.

One urgent condition that must be ruled out is testicular torsion, which happens when the testicle twists and cuts off its own blood supply. Torsion is a surgical emergency.

Signs that may suggest torsion instead of epididymitis:

  • Sudden, severe pain
  • Nausea and vomiting
  • Pain that starts abruptly
  • A testicle that sits higher than usual
  • No relief when elevating the scrotum

If pain is severe and sudden, seek emergency medical care immediately.

When in doubt, always treat sudden testicular pain as urgent until evaluated by a doctor.


How Doctors Diagnose Epididymitis

Diagnosis typically includes:

  • Physical exam
  • Urine test
  • STI testing (if appropriate)
  • Ultrasound of the scrotum

An ultrasound helps rule out testicular torsion and confirms inflammation of the epididymis.

Doctors rely on evidence-based guidelines from urological and infectious disease experts to determine the correct diagnosis and treatment plan.


Medically Approved Treatment for Epididymitis

Treatment depends on the cause.

If caused by a bacterial infection:

  • Antibiotics (usually for 10–14 days)
  • STI treatment for sexual partners if applicable

Supportive care:

  • Rest
  • Scrotal elevation
  • Ice packs (15–20 minutes at a time)
  • Anti-inflammatory medication (like ibuprofen, if safe for you)

Most men improve within a few days of starting antibiotics, but it's essential to complete the full course, even if you feel better.


What Happens If Epididymitis Is Not Treated?

Untreated epididymitis can lead to:

  • Chronic pain
  • Abscess (pus collection)
  • Reduced fertility (rare but possible)
  • Spread of infection

This is why early treatment matters.

The goal isn't to scare you — but to emphasize that scrotal pain should not be ignored.


When Should You See a Doctor?

You should seek medical care if you have:

  • Any unexplained scrotal pain
  • Swelling lasting more than a few hours
  • Fever with testicular pain
  • Pain during urination
  • Penile discharge
  • Sudden severe pain

Even mild symptoms deserve evaluation. It's far better to rule out serious causes early than to wait.

If you're unsure whether your symptoms match those typically associated with Epididymitis, you can use this free AI-powered symptom checker to help identify what might be causing your discomfort and determine how urgently you should seek care.

However, an online tool does not replace an in-person medical exam.


How Long Does Epididymitis Last?

With treatment:

  • Pain often improves within 1–3 days
  • Swelling may take several weeks to fully resolve

Mild discomfort can linger even after infection clears. This is common and usually temporary.

Chronic epididymitis (lasting more than 6 weeks) may require additional evaluation by a urologist.


Can Epididymitis Be Prevented?

Prevention depends on the cause.

To reduce risk:

  • Practice safe sex (use condoms)
  • Get tested and treated for STIs promptly
  • Treat urinary infections early
  • Follow post-procedure medical instructions carefully

There's no guaranteed way to prevent epididymitis, but reducing infection risk significantly lowers your chances.


Key Takeaways About Epididymitis

  • Epididymitis is a common and treatable cause of scrotal pain.
  • It is usually caused by bacterial infection.
  • Symptoms often develop gradually.
  • Sudden severe pain may signal something more urgent.
  • Early treatment reduces complications.
  • Antibiotics are effective when infection is the cause.

Most men recover fully with proper care.


Final Word: Don't Ignore Scrotal Pain

Scrotal pain can feel uncomfortable and worrying, but in many cases, the cause is manageable — especially when treated early.

That said:

  • Sudden severe pain is an emergency.
  • Fever with scrotal pain needs urgent care.
  • Persistent symptoms require medical evaluation.

If anything feels severe, unusual, or rapidly worsening, speak to a doctor immediately or seek emergency care.

For milder or unclear symptoms, start by understanding what might be happening, then schedule a medical visit to confirm the diagnosis.

Your health — especially when it comes to infections or potential emergencies — is not something to delay.

If you're experiencing symptoms, consider using this free online tool to check your Epididymitis symptoms, and follow up by speaking directly with a qualified healthcare professional.

Prompt action leads to faster recovery — and peace of mind.
