Epididymitis
Epididymitis is inflammation of the epididymis, the coiled tube behind the testicle, usually from infection. It causes scrotal pain and swelling and needs prompt treatment.
Causes & risk factors
- Urinary tract infection spreading to the epididymis
- Sexually transmitted infections in younger men
- Recent catheter or urinary procedure
- Enlarged prostate causing urine backflow
- Rarely, non-infectious inflammation
Common symptoms
Tests & diagnosis
- Scrotal ultrasound
- Urine test and culture
- STI testing where relevant
- CBC
- CRP
Treatment & management
- Antibiotics appropriate to the likely cause
- Pain relief and anti-inflammatory medicines
- Rest, scrotal support and ice packs
- Treating a partner if an STI is the cause
- Follow-up to ensure it settles
When to see a doctor urgently
- Sudden severe testicular pain — urgent (to rule out torsion)
- High fever with a swollen, red scrotum
- Pain not improving on treatment
- A hard lump remaining after the infection settles

Frequently asked questions
How is epididymitis different from testicular torsion?
Torsion causes very sudden, severe pain and is a surgical emergency. Epididymitis usually builds more gradually, but sudden severe pain always needs urgent assessment to be safe.
Do I need antibiotics for a long time?
Often a course of one to two weeks is needed, sometimes longer. Complete the full course even if you feel better, and attend follow-up.
