I propose a new method of pain measurement:
The number of Huertz (including Killohuertz) on the Ouchdamnitometer.

More on topic: I once had a partial herniation of my esophagus over my diaphragm, which caused my diaphragm to spasm constantly. It felt like someone was stabbing me in the throat from the inside.
I've also seen some unpleasant things: in Whiskey 3 (Whiskey is a series of skate/snowboarding movies) one of the principles does a back flip off a movie marquee and breaks his thighbone. Superbly nasty. And in high school, one of our wrestlers got taken down onto his neck and snapped a couple of vertebrae. That's a sound I'll never forget. *shiver*
