hello i'm 18, when i was about 15 i found a lump on the back of my left testicle, almost at the top. right at the top of the epididimus(sp?) its hard, will not move and is about the size of a small grape/marble, it is painless by itself and also painless to touch other than a little achy when squeezed, the size has not changed, as far as i have noticed since i found it. I dont know if this has anything to do with my condition, but my sister just had her ovaries removed due to cysts, could this be a cyst, are there hereditary conditions like that,? any info would help,
Thanks,
CC
