Pain

I have a very high tolerance to pain. Yesterday I scratched my wrist and made it bleed, but didn't feel it. I didn't notice it until the evening when I changed my jumper. I often find bruises but don't know what had caused them. When I had my wrist operation, I took quarter doses of the painkiller for three days, but didn't take any at all after that. I think again that this is to do with Aspergers, and the way that one's brain processes information. I know one person who has the same trait, and have read of others who share it.
