Be, what is it that hurts? I have trouble with sitting too, because one of my legs is messed up (nobody can figure out why) and it hurts if I can't put it up or just say the heck with it and lay down altogether. It hurts if I walk very long, too (long being a relative term - like 20 minutes anymore

).
If it's your leg, try wrapping it up with an Ace bandage, sometimes that helps me. Anything else, I don't have any really good ideas, sorry.
Love, Candy
