A few days ago I started getting this pain in my left nut and I thought it would go away. After 3 days I decided to go to the doctor just to be safe. It turns out I have epididimitis and testicular appendicitis (who knew your nuts have an appendix lol) Anyway... I am a boxer guy and the doc said that I had to wear a jockstrap for a couple of weeks (not gonna happen). Then he said that I should throw out all my boxers and NEVER wear them again. He said "you have too much bouncing and jiggling around down there and you are going to hurt yourself." HAHAHA I smiled and told him the boxers were staying.
