Same here. I usually dig my fingernails into my arm, not deep enough to break the skin.
I enjoy some types of mild pain, and I have a high tolerance for pain in general. But I have a very low tolerance for being ill.
I dig my fingernails into my skin, I've run my thumb along the edge of my desk (this actually hurt noticeably, but that was okay), I've hit myself, I've bitten myself, although the last two more when I was a lot younger. I've got this pair of scissors that I run the point along my skin hard enough to be painful. It won't ever break my skin, but it works.
I am terrible about illness. It just knocks me out. In fact, I'm ill right now and pretty miserable about it.
