There may be different reasons why men and boys experience lumps, swelling or pain around the testicles. These symptoms should be reported to your doctor who can check why this is happening and make sure more serious conditions are treated early.

A bump or blow to the testicles can cause severe pain and feelings of nausea and may even cause someone to be sick. These feelings should pass quickly and it is best to lie down and try to relax until it passes. If the pain continues or you notice any swelling, you should get this checked out by the doctor. In some cases, the blow can result in fluid building up around the testicle (hydrocele), or the testicle twisting (torsion).
This condition affects newborn babies or the very young. At birth, one or both testicles are not yet in the scrotum. This normally resolves within the first month, with the testicle(s) normally dropping down from the groin, but when this doesn’t happen, a small operation may be required.
