Yeah, as jimi said, it's actually a pretty common thing. Most people don't realise that AS is more than just a social disorder.

There is a great little article here about it. http://www.psychologytoday.com/blog/...body-awareness

Like the guy who wrote the article, I had appendicitis as a teen. By the time I told anybody I was in pain, it had already ruptured and formed abscesses along my bowl. I ended up having to get a section of my bowl removed. According to the surgeon, if I'd waited even another day I wouldn't have made it through surgery, but to me the pain only seemed worth complaining about after several days.
