I'll throw in with the sympathy and similarly scary cancer moment with, "you need to get that checked, and I mean now!" My scrotum swelled up, and I could barely walk. Went to the local emergency room, and was immediately referred to a urologist.

(I wasn't riding a this point, it was nearly 20 years ago.) I've had off and on reoccurances since, and have found that increased stress levels have contributed. Cipro is powerful, and I had great success with it. Keep in mind antibiotics tend to reduce your skin's ability to cope with UV rays, so use extra sunscreen.

Anyway, hope you feel better, keep us posted on your progress, and be gentle with he boys.
