Flash paper getting stuck to my hand is a common enemy....
Also somehow screwing up SAW and then cleaning it with alcohol... you could say it stung.
Usual hand pains from sleights and small cuts from decks, nothing major.
However, some injuries I have heard of include,
Copperfield's stage hand and the big fan
Multiple magicians dying from both the bullet catch and buried alive
People suffering injuries from botched russian roulette routines
The infamous tiger attack
Really the injuries than can be sustained from magic, or any performing art for that matter, are innumerable. But if everyone was willing to take the bumps and bruises we wouldn't have an art form, would we?
