I broke my index toe acting like a hooligan backstage in the dark. There is a reason why I wear boots at work now. I've burned myself a fair amount too, either by being a naive cook or by handling hot lighting equipment. I actually don't have feeling in parts of my hands as a result. I've got knee problems too, I don't know what brought it on, but I wear a brace when I work now.
I've slammed my head on enough things it would probably be safe to say I've had concussions.. Once I was sitting on a pipe grid about 10 feet in the air, lost my balance, smacked the back of my head into the wall behind me and landed on my back on a pipe below me. I'm amazed I didn't fk myself up, I was working alone too, so if something had happened..
The only other thing that comes to mind is a sledding accident when I was little. I crashed headfirst and got a pretty bloody lip. Amazingly I did not break any teeth or my nose, and I didn't need stitches, but I did sever my frenulum (the tissue that connects the upper lip to your gums). For several weeks after that I had trouble eating a lot of foods. By doctor's orders I had a steady diet of pudding, jello, and ice cream. I was fine with that.
