Twice... Broke my jaw in a car accident when I was 17 & had to have some dental surgery to replace a couple teeth, wasn't too bad except for living off soup through a straw for three weeks.
Second time I had sinus/nasel surgery to correct an obstruction in one of my sinus's & a deviated septum, had a "local" instead of them putting me out & I remember the doc breaking my nose with somthing like a chisel...it made a sound like pulling a wing off a chicken!
The worst part was afterwards believe it or not... I had cotton stuffed up my nose for three days & on the fourth it had to be removed... felt like I was having my brain yanked out through my nostrils!!!
