why does my spine tingle from time to time when I pee?

Are you male or female?

male

lumbar or thoracic?
(or cervical, i guess, but that’d be surprising)

This is one of the greatest questions I have ever read on this site. I’m serious.

Same thing happens to me. Is this universal for guys?

”Post-micturition convulsion syndrome, also known as piss shivers, pee shivers, peegasm or whiz willies, is a phenomenon in which one feels a shiver running down the spine following urination.”

There is no agreed explanation on why it happens, though the artice has a few hypotheses. Apparently, 83% of males and 58% of females who answered an online poll said they have exprienced it.

same with me

I always assumed it was a reaction to the lessening of pressure on your bladder since I usually only feel it after going a long time without a bathroom break.
