What was your most painful experience?

I have a lot of those. One time while I was riding my bike I flew into a ditch after skinning almost my whole leg, had to walk home with a leg covered in mud and blood. Oh, and another time way long ago I dropped a five pound weight on my foot which made it swell up and turn blue-purple. I also hit my head which made a hole in it so they had to staple it shut, that was so uncomfortable but it didn't hurt too much. I've had a lot of painful moments but I can't which was worse.
