I've got about five of 'em. Most pain, I'll go with:
Working construction in a snow storm.

Holly crap, that's awful!
By the way, I'm still waiting for Tiffany, kurandoinu, harpy, morgia or any other gal to post in this thread.
How come only the dudes are lucky enough to get horrible disfigurating accidents while running around careless like headless turkeys?
Oh, I know what they'll say: it's been scientifically proved that women have a higher pain threshold than men, because they need to prepare to giving birth, which is apparently pretty ouchy.
I guess their biggest pains would be like this: taking it in the ass, getting their crotch waxed with wax and not, say, laser, and having a baby come out of their vagina, instead of the more modern and classy I-get-a-C-section-so-my-vagina-remains-its-normal-size-and-I-don't-have-to-have-a-labiaplasty-afterwards approach.
