Severe burns.
Pretty bad, yeah. Especially later on.
It usually doesn't hurt at first due to the nerves dying from the intense heat (apart from the initial pain, of course, but then you'd go numb), but when the nerves start to heal (if they can).... Ouch.
I think they're overrating cluster headaches in that wiki article; they're bad, yeah, and if it was a constant thing 24/7, life would really, really suck, but they're usually gone within a couple of hours at most, then there's a respite. Sure, you dread getting another to begin with, but like with most things, you get used to it.
O, the worst "pain" I've felt is actually anxiety.
