I have never in my life experienced any such thing. As far as I know, none of my three sons has, either.
This is the very first time I’ve ever heard of such a thing, and I’ve been around a long time.
Wikipedia describes it thusly:
Post-micturition convulsion syndrome, also colloquially known as piss shivers, pee shivers, piss quiver, is a phenomenon in which one feels a shiver running down the spine following urination.[1] The shiver can produce a brief twitch, which is a form of myoclonus. It should not be confused with post-micturition syncope, a feeling of faintness following passing urine.
To date, despite years of discussion and theorizing, there is no agreed-on explanation of the phenomenon[2] and no medical research into it. However, it has been mentioned occasionally in columns, and in one Internet poll, where about 83% of males and 58% of females reported experiencing it. By 6 Jul 2007, more than 24,000 males and more than 1,200 females had responded to the poll on the syndrome.
I have never in my life experienced any such thing....I did once after a night out in Saigon and about a week later. The nice doctors gave me a P-P shot and that was it.
I'm with you, I am 67 years old and have never had a PP shiver, and I have peeded quite a few times in those 67 years. I have never heard of it until today on this thread.
