I am a 17 year old male. A few days ago I was doing my monthly self check. I felt a small pea shaped ball near the top of my left testicle. It doesn't seem that it is attached directly on the testicle, but it is attached. I did the examination sitting down, as I sprained my ankle last week and have trouble keeping balance without a crutch. Today, I felt it while I was sitting down, but I was able to repeat the examination standing up. I felt the ball clearly while sitting down, but not when standing up. Would this effect my diagonsis? Is that common?
My left testicle seems to feel denser, or harder I guess, then the right, but the two are relatively close in size. There is a little pain during the examination, but I don't know if I am just being to "rough" with the examination.
I don't know what to do, as telling my parents would be embarassing. I guess I just need a doctor's advice before consulting them, as I don't want to make a doctor visit for no reason. Any advice would help.
