Hello, yes the other day I noticed a swelling on the middle of my testicle (the sack not the actual testicle) it is sore and tender and looks as if it may contain pus - but is unable to "pop". It has swollen to the size roughly of a quarter of a testicle, is painful and sore, like a bruisey type feeling, it is firm as if it is an inflammation of somesort but i am not entirely sure, your help is greatly appreciated
