That said, this also could be the biking activity drawing attention to something else. If your testicles are important to you, see a doctor. Else, take the advice of others here who have
1) likely no medical degree

Seriously. Steve Jobs trolled the internet for new-age miracle cures for a cancer that was eminently treatable, with a high likelihood of success, using conventional therapies. This delayed him getting the standard treatment, and this delay killed him. See a doc!
You ever go to the doctor with something as vague as that? I have, and they usually say "sounds like you did something on ____, I wouldn't worry about it." That's why I suggested quickly ruling out the likely suspects before you go to the doctor. Nowhere did I suggest ignore it for years while you treat it with loganberries. He's not going to keel over from something if he takes a couple days to see if he can sort it out before running in to the doctor.
