My worst injury wasn't in martial arts, but my second one is. (I get hurt by the stupidest ways...) I slipped off a vine from a tree at my grandma's house and fell about 10-12 feet from the ground on my hip. I dislocated my leg. Karate has helped that though since it doesn't pop much anymore. That was pretty bad- couldn't move it, and had to crawl and roll on the floor to get throughout the house. Worst part was nobody believed me- so no one took me to the hospital! eventually it somehow got better and was able to move it later on. It hurt SO bad if I sneezed, coughed, laughed, anything! haha Another time was at a tournament though--- I kicked shins with this big guy- It hurt incredibly, more so later on than during the match. Thought I fractured it- but just bruised the bone some. That was a very weird injury since it hurt everywhere but the place I hit it. which is reffered pain if you want to look it up
