What is your most traumatizing chess experience?

I don't recall anyone blowing their knee out from chess, or getting a concussion.
Someone once actually got a concussion from playing chess….

In 1251, a chess player in Essex lost a chess game, which angered him so badly that he stabbed his opponent to death.
chess can be rough sometimes.

Don’t forget to eat your chessables.

Most traumatizing experience that I had was when someone in the chess club I was in tripped against the leg of a table, and started choking on a bishop.
