Yea, burning hurts. It's hard to place which pain has been worse for me, regular burns (fireworks or something like that) or sunburn (frustration at the burning feeling all the time). I haven't had anything as bad as other users have had. Does anybody else enjoy taking a shower with sunburn? Sure it hurts, but I like making it hurt enough in the shower that for a little while, the burning sensation goes away... Until you exit the shower of course, but maybe I'm just a freak.
If you want to try some insane pain, try getting an ingrown nail on both sides of both of your large toes. I had that and every step, brush up against, touch, ect felt like I had a knife buried inside of my toe. I couldn't even do normal things like sleep because even the sheet on my bed would cause tremendous pain (same thing with socks). Don't even get me started about times when I bumped my foot into something like a chair or a table. Getting it removed (which is an experience of it's own) is great because what had caused you INTENSE pain the day prior doesn't even phase you.
