Pain isnt a physical thing per se. Pain is just your brains reaction to injury basicallly telling you "Hey, motherfucker, get that wound cleaned out" or some shit. I was in a skiing accident where i had a bone in by forearm broken in 2 places, hand absolutely smashed to shit and a few bruises on my back. Funnily enough, the bruises hurt the most. Pain is all about what you want it to be. Focus on something else and you're good to go.
