LOL…:
“Cello scrotum,” a nasty ailment allegedly suffered by musicians, does not exist and the condition was just a hoax, a senior British doctor has admitted.
In a letter to prominent medical magazine, the British Medical Journal in 1974, Elaine Murphy reported that cellists suffered from the painful complaint caused by their instrument repeatedly rubbing against their body. [...] But Murphy, now a baroness and a former professor of psychiatry of old age at Guy’s Hospital in London, has admitted her supposed medical complaint was a spoof.
“Perhaps after 34 years it’s time for us to confess we invented cello scrotum,” she wrote with her husband John, who had signed the original letter, which was published in the BMJ on Wednesday. “Anyone who has ever watched a cello being played would realize the physical impossibility of our claim.”
All you need to know about how funny I think this is is that back in tha day a friend of mine used to joke, in reference to ailments like “tennis elbow” & “swimmer’s ear”, that there was a medical condition called “stripper’s ass”.


The ailment exists. It’s just not caused by friction with a cello (well, it could be, but not if you play it right).
..as in “don’t play the cello while naked”?
BTW: I’ve heard of some DJs getting friction burn from the platter on their turntables before.
