Hi, I have some questions...

To get to the point, I'm 28 and my left testicle has been a bit sore for about a year or so now. I saw a specialist around when it first started hurting and he did some tests and didn't think it was anything to worry about. He said that soreness is common. I have not felt any lumps necessarilly but am concerned.

Every so often I'll sit weird or brush my leg against my testicle and it hurts, not unbearably or anything, but pretty sensitive. I also feel the need to mention that this sensitivity has never hurt during sex and has not previously caused any sexual dysfuction.

I am planning on going to a doctor VERY soon! Please help me out with advice /suggestions. That's it for now! Thanks, guys.
