So, I am 14(turning 15 in a few months) years of age. My problem? Well, One day I was sitting down playing my guitar and when I got done I stood up to put it away and when I stood up it was as if my right testicle got an electricle shock. It was temporary, the problem is that it occured about 2 months ago and I can still feel like my right testicle is extra touchy, sensitive, dull aches. and every now and then it also occurs in my left testicle and lower left and right abdomen also my lower back. I do lift a lot with my back. There is no sign of any abnormalities or lumps in my testicles. But it could be a vein in my abdomen leading to my scrotum, I have no idea really. It is most of the time just butterflies in my testicles but lately it is more dull and constant pain.
