What is the worst pain you've ever experienced?

An acquaintance of mine from school recently committed suicide, mentioning persistent "cluster headaches" in his note. Another friend of mine was discharged from the hospital a few weeks back after dealing with some hellish-looking kidney stones. A couple years back, a buddy of mine who was finishing up his fourth tour in Iraq was hit hard by an IED, and had to drag himself to safety with a completely shattered leg. In his words: I was praying to whoever would listen to either die or let the shock set in. Nothing happened. Just pain.

I've had a pretty sheltered life. Nothing worse (yet) than a direct shot of wasp spray to the eye, and a heavy suitcase falling onto an inflamed volar ganglion cyst on my wrist (I almost passed out from the pain).

What kinda gay shit can you faggotrons come up with?
