A week ago I had a dull ache in my right testicle and groin. I googled the symptoms and all said I would be rendered infertile! It didn't help that just last night I discovered a tiny, hard lump on the top of my testicle. The lump is about the size of a pen tip. It is honestly not noticeable. I'm so scared about going to the doctor and being told I need a testicle removed. Is it testicular cancer or something else?
