re: Most physical pain you have had?

Fell a few feet onto concrete, and first point of contact was my left knee. Obliterated a bunch of cartilage and moved the patella, but at 14 years old thought I'd walk off the pain. Made it home from school with a knee swollen 2 or 3 times normal and went to ER. Doctor told us they'd have to drain the fluid, and clarity of the fluid would tell them how bad the damage was. It appeared to be all blood. Making matters worse, he was basically stabbing me in the knee with a large bore hypodermic repeatedly because there was lots of fluid and he was in a hurry. He was just filling up dixie cups with what he got out.
