Or could it be that sitting puts pressure on a nerve that is not compressed , but which is deprived of oxygen because of reduced blood flow to the nerve and so is more sensitive?sage721 wrote: So, then I start thinking compression. I think that I must be putting pressure on a compressed nerve while sitting.?
Have you tried alternate cold/hot baths as described by Violet?
I've found that a hot bath always at least temporarily stops pain . I'm not sure why changes in temperature would stop pain from a nerve that was compressed or damaged but I can understand why blood flow would be increased by external heat. Perhaps someone more knowledgeable can explain.
