Hi,
i have had this problem too for about a month or two now. I have this annoying pain in my left testicle and it happens about once every two weeks, and ONLY, but not always, when i go outside wearing jeans and when its a little cold. Every step i take it hurts my testicle and it gets really uncomfortable, and i tend to masturbate a lot which i suggest might have something to do with it. I returned home and noticed the under part of my left testicle is bigger than the right, and it hurts when i touch it, but this pain, within 10-15 minutes goes completely away, except for the size of the right testicle, it becomes smaller but still bigger than the right, but it doesn't hurt anymore. It happens only when i go outside and its cold and i'm wearing jeans, not when i masturbate or wear tight underwear. No matter what i wear in my home i feel fine, outside it changes as if the cold affects it. Also, the pain spreads in my left leg, the area next to my left testicle and gives me a pain that that seems to move to my stomach too, as if my balls have been hit by something and the pain later travels to the stomach. Any doctors or experts that have knowledge on this and would like to give some advice and views on this i would really appreciate it, doctors are just too expensive and i need some help before i go to one.
Thanks in Advance
PS. I have had this for 1-2 months
