I am facing a similar situation, and teaching is one of the possible solutions I'm considering. At the moment I am teaching English abroad, which is a relatively low stress job physically. Even so, I am still in pain much of the time.

Do some searches on the forums (keywords job, employment, work, etc.). There are a few threads that touch on this topic. What people end up doing seems to depend a lot on their training and background. It also depends on your specific symptoms (for instance, some people can't use a computer but they can drive a car, some cannot do either, etc. and so forth).
