Is it normal for one of my testicles too be smaller then the other testicle in my ball sack? Also, when I tried running or juging my front lower caffs start hurting so bad I can't jug for long any more, I tried icing them but it didn't work. Oh every once in a while I get pain inside my penis is that normal but it's not Bad. Last question when I run or jug for a short period of time I run out of breath and can't catch it and I don't have assma,
