I had a connecting rod go through the block on my xB. Seeing the hole and all the oil and antifreeze pour out of it was quite painful for me.

Physically, the worst was tearing my knee cartilidge in a state wrestling match. I was standing at the time, let go of my competitor and was screaming, but of course the ahole ref lets the other guy sweep my leg for a takedown and points before stopping the match. One piece had wedged itself under the other one in the outer joint, so moving it to either side was horribly painful. The worst though was when they got me to the training table. One of the trainers put his fist behind my knee and pulled on my leg to open the joint up while the other pushed in to pop it back into place. Osn't bad after that, though I needed two scope surgeries to fix it.

In a close second it's a tie between having all four wisdom teeth pulled at once and getting a herniated disk. The teeth at least i was given drugs for, with my back I litterally could not move after waking up or it would hurt so bad I'd be yelling. To get out of bed, I had to raise one knee up to my chest while laying on my back, grab on to my leg and then kick forward, letting the momentum sit me up because if I tried to do it with my stomach and back muscles it would hurt too much. Three months of physical therapy and I was finally back to normal. Glad i didn't have surgery even though recovery took longer.

Only other really bad thing has been a kidney stone. never fun but not as bad as the others.
