I've been to the hospital for concussions. My mother took me to the emergency room once because I had a gash on my face which didn't turn out to be such a big deal after all, but I wouldn't have gone if she'd given me any choice in the matter. I also went once because I injured my leg in a soccer game; everyone heard a loud "crack" when I got tripped up and landed funny (where was the bloody red card?!). I couldn't stand on my own, and my leg hurt like hell. Turned out it wasn't broken, but I had to wear a binding full-leg brace for a weak.

I go to a physician if I've got a cold and OTC drugs aren't working. Other than that, I generally avoid the doctor's office.
