I've had something flair up "down there" twice. The first time it was diagnosed as epididymitis after an extensive exam, and it went away with treatment. The second time I saw a general practitioner who wrote it off as a "boggy prostate". Both times the symptoms were intermittent, shooting pains that would really grab you by the... well, you get the picture. No red skin. Both times this happened I just happened to be doing some lifting. By which I mean the episodes were 10 years apart and both times I was in a period where I felt I needed to do squats to build some leg strength. Coincidence?
