I got ehm, Hernia, and I don't know whether I should have it removed or not.
I red up on Internet that some sorts of surgical treatment might cause permanent pain in the groin in the future.. is that true? Can one avoid it and still have it removed? My testicles are taking abnormal size and I am truly starting to hate it.

It truly depends on what kind of hernia it is. There are several kinds. If your testicles are swelling you should seek immediate medical care.

Its not testicle that's swelling is that damn Inguinal Hernia
