i have a pretty high pain tolerance, and always have. i got hurt a lot as a kid, and dealt with some painful, repeating conditions like chronic ear infections and things. that all got me pretty well adjusted to pain. that's not much help, i'm sure. but, all that also helped me learn two things:
1. pain can cause pleasure--
i had a horrible infection once, and the pain was pretty intense. sitting in the hospital, i started laughing. my mom freaked out a little, but i just kept laughing until my eardrum ruptured and pain went away. the body combats pain with hormones and endorphins and other brain words. those can actually cause you to feel slightly elated. it's a little strange, but i sort of like pain now (and by sort of, i mean sort of a lot...except headaches). i'm not talking about anything too weird, but if i scrape an arm or leg climbing a tree, it feels good because i've come to recognize that other feeling. that has only led to an increased pain tolerance.
2. pain is a good thing. one of the problems with a high tolerance is that you don't fix problems before they become bigger problems. pain is the body's way of saying something is wrong. if your ankle hurts, the body is telling you to rest. if your head hurts, drink some water or take a nap. it's not necessarily a tolerance that is beneficial, it's knowing how to get rid of the pain without drugs
