NHS 111 can tell you the right place to get help.

Sudden, severe testicle pain can be caused by twisting of the testicle (testicular torsion).

This is a serious problem that can lead to the loss of the testicle if it's not treated quickly.

Less serious causes of testicle pain include:

• an infection (epididymitis)
• an injury
• an inguinal hernia
• a build-up of fluid (cyst)
• swollen veins in the testicles (varicocele)

Pain by itself is not usually a sign of testicular cancer. Cancer usually causes other symptoms like a lump or swelling in your testicle.

Do not try to self-diagnose the cause of your pain. Get medical help if you're worried.
