My OH had an achy/pain feeling in his groin last week and now he says that he can feel a small (moveable) lump on the tube near to (but not on) his right testicle.

I said he should pop to the gp but being a typical male he says he is going to leave it for a while a keep a check on it!

I googled the symptoms and came up with a cyst on the epididymis but not sure.

Wondering if this is common?
