I poke and prod!
Yeah, sure pain hurts like hell, but it's just a feeling. If you can rationalise it through curiosity, it seems to dull it to a bearable level. Just shrug your shoulders, open the wound, peer inside and then fill it with superglue!
I get hurt all the time at work (in a bodyshop, lots of sheet metal, cuts, scrapes, bruises etc..), over the past five years, I've toughened up a lot. It takes a pretty serious injury for me to stop what I'm doing now!
It all began at the point I was run over by a 54 seater coach. Hurt like a ************, but once the pain's there, you just have to overcome your mind, which is your own worst enemy if you can't control it.
