Long story short. Back in High School, I got kicked in the nuts so hard, I almost had to spit them out. (football injury) It was the left one that took the worst of it. All is well, I have 2 kids so I know I'm okay.
It seems like everytime I cycle some gear, that nut gives me trouble. I will be just driving or something and get the worst pain I have ever felt. But I only notice it while I'm on cycle.
Any suggestions
