As of last week i had a very sharp pain run through my left testicle for about 3 minutes.. and then it went away. About 3 days later (I think), I noticed that said testicle was hard, and maybe a bit swollen.. but was tender to the touch. I havent been to have it checked yet, as i have no insurance.. So I was curious if someone had an Idea as to which direction I should be looking. Any ideas as to what could be the problem?
