My husband has been plagued with this on and off for the past 25 years. The only thing that seems to help is a full course of strong antibiotics such a Cipro and - here is the most important part - a total avoidance of caffeine! Even one or two cokes can set off an episode. He also makes sure he wears underwear with a lot of support that hold the testes close to the body. Good luck and try avoiding all caffeine. If it works for my husband, it's worth a try!
