I am 17 years old and run track and cross country. My left testicle is also over twice as big as my right. When i got a school physical, the nurse said that i had vericocele veins in my left testicle. Since my left testicle is pretty big, when i run, it gets pretty sore and chafes because it rubs against my boxer briefs. Is there anything I can do to stop this rubbing?And is there anything that I can do to lessen the size of my testicle or fix the big veins in it, like make them smaller? Please help, I just don't know what to do.
