Epididymitis

Epididymitis is where a tube (the epididymis) behind the testicles becomes swollen and painful. It's often caused by an infection and is usually treated with antibiotics.

Check if you have epididymitis

Symptoms of epididymitis may include:

  • sudden or gradual pain in 1 or both of your testicles (balls)
  • the bag of skin containing your testicles (scrotum) feeling tender, warm and swollen
  • a build-up of fluid around your testicle (a hydrocele) that feels like a lump or swelling

Depending on the cause, you may have other symptoms, such as difficulty peeing, or a white, yellow or green discharge from the tip of the penis.

Causes of epididymitis

Epididymitis is usually caused by a sexually transmitted infection (STI), such as chlamydia or gonorrhoea. This is more likely in younger men under 35 years old. In men over 35, the main cause is usually a urine infection.

If testing shows that your epididymitis is caused by a STI, it may be recommended that your current or recent sexual partners (over the past 6 months) are also tested for STIs.

It can also be caused by a urinary tract infection (UTI), but UTIs are less common in men.

A UTI is more likely if you have:

Less common causes of epididymitis include:

Non-urgent advice: See a GP if:

  • you have a lump in your testicles
  • you have swollen testicles
  • there's a change in the shape of your testicles
  • you notice a change in the way your testicles feel
  • 1 testicle becomes bigger than the other
  • you get aching or discomfort in your testicles that does not go away

Lumps in the testicles can be a sign of testicular cancer. This is easier to treat if it's found early.

Sexual health clinics can help with epididymitis

You can also get treatment for epididymitis at a sexual health clinic. They can provide the same antibiotics you'd get at your GP surgery.

Many sexual health clinics also offer a walk-in service, where you do not need an appointment.

Find a sexual health clinic

Immediate action required: Call 999 or go to A&E if:

  • you get sudden, unbearable pain in your testicles or tummy

This could be caused by your testicle becoming twisted and needs to be treated in hospital as soon as possible.

Information:

Do not drive to A&E. Ask someone to drive you or call 999 and ask for an ambulance.

Bring any medicines you take with you.

What happens at your appointment

If you go to a GP or sexual health clinic with symptoms of epididymitis, you'll usually need some tests first to find out the cause.

These may include:

  • a groin examination
  • a swab of the tube that carries pee out of the body (urethra) – to test for infection
  • urine and blood tests
  • a rectal examination – to check for problems with your prostate

Treatments for epididymitis

The treatment for epididymitis is usually antibiotics. They're given as injections or taken as tablets, or a combination of both.

It's important to finish the whole course of antibiotics, even if you start to feel better.

You should start to feel better within a few days, but it may take up to 3 months to fully recover. If you still have symptoms after this, you might be referred for further tests.

Things you can do to help with epididymitis

If you're recovering from epididymitis, there are things you can do to help ease pain and swelling and prevent any further problems.

Do

  • take painkillers, such as paracetamol or ibuprofen, to help with the pain – if you have a history of seizures or fits, NSAIDs such as ibuprofen should not be taken with some antibiotics used to treat epididymitis; speak to a pharmacist about the best painkiller to use if you're unsure

  • hold a cold pack (or a bag of frozen peas wrapped in a tea towel) on your groin

  • wear underwear that supports your scrotum

Don’t

  • do not have sex if you have gonorrhoea or chlamydia until you have finished the full course of treatment, or for 7 days after
