I'll tell you what hurts. Just got back from a wakeboard camp. 4th day, afternoon, 1st of 2 sets. New driver. We aren't even at the turning point on the lake, but she(the driver) decides to turn without warning. Bad thing is, I'm in the air on a heelside jump. I'm going one way, the boats going the other. Result: ruptured right ear drum, pulled right groin, concussion and the board came up and hit my left butt cheek so hard, that whole butt cheek is black and blue. Almost punctured the skin from the points of the board. I'd post a pic, but nobody wants to see that.
