You can actually learn to stop being bothered by pain, i'm not sure what extent this goes to but try next time you cut yourself or anything, just think: 'actually this doesnt hurt' and it sort of stops hurting. It's kinda cool, works with cold too, but as i say dunno to what extent.
Think it's related to the placebo effect stuff.
Being a joiner i get cut on my hands quite often , to me its part of the job (just try telling that to the h.s.e.)
You tape it up and just get on with it .
I once walked 20 miles after going over on my ankle , i was in the middle of nowhere in the highlands .
only later when i got to fort william did i find out i had broken a bone in my foot , it did hurt but you just grin and bear it .
