Oh, holy shit! Oh, motherfucker! It's the hollering I've done when I've gotten a ball twisted. It's no fun. No siree, it is not.
The symptoms of a twisted testicle, depending upon the amount of torsion - and your pain threshold - can register as a dull ache running up into the lower abdomen to a sharp stabbing sensation that can literally make you feel nauseated and dizzy; you may actually vomit; you may pass out. That nut will most likely swell.
I dropped trou, dangled my balls over the edge of the bed
Then gently - very damn gently - tapped and massaged it until the worst of the pain stopped.
I was told by that old Shaman friend of mine that I called - who was also a doctor - I'd done exactly the right thing. If that hadn't worked, he said, "get thee to an emergency room post haste. And I do mean fast!" Then he told me if the ball swelled, or the ache did not ease within a day, I should still go to the ER. The pain involved will most likely remove any amount of shyness, but... When you arrive in an ER you need to be up front with the Triage Nurse about your reason for being there. Why?
