Yes indeed. Many times. Usually after flogging my cock very vigorously for many hours. You didn’t say whether you had been pleasuring yourself or not. Given it’s meth we are talking about I’ll assume you have been.
I think it is a combination of the bottom of my hand bashing my balls on the downward stroke somehow coupled with vasoconstriction. It is more common when I feel the need to piss but have to really strain to get something out.
It can be very frustrating if you are still as horny as hell, haven’t cum, but your testicles can’t take any more.
Several times I have found the pain to be so bad that I could barely walk, which really put a downer on my high.
As regards treatment the obvious thing to do is stop beating your meat. I also found relief with an appropriate temperature hot pack between the legs for an hour or so. Rx anti-inflammatories I had for an arm injury also worked well. I did try rubbing in Voltaren emulgel anti-inflammatory gel. It was a little bit stingy and also made me hornier but it seemed to reduce the pain.
I’ve noticed viagra helps as well. It relieved the vasoconstriction.
The good news is that having suffered a pretty severe incidence of this maybe 6-7 times I don’t seem to have any permanent damage and I’ve learned to be a bit more careful with how hard I flog myself.
All that said, there are conditions that can be caused by drug use that cause pain down there and are quite serious. If you stop fapping and don’t feel any relief at all after an hour or so then consider going to ER.
Also straining to piss when reasonably well hydrated can cause real pain in that area and also be damaging to your plumbing.
