Epididymo-orchitis is an infection of your testicle and the tubes attached to the testicle, which are called the epididymis. It causes pain and swelling in your testicle, and it may also be painful to pass urine (wee). It is usually caused by a sexually transmitted infection. But it can also be caused by a urine infection. In boys, it can be caused by mumps.

If you have pain or swelling in one of your testicles you must see your doctor. If the pain is sudden and severe it may mean a twisted testicle, which needs to be seen immediately.
