Oh wow, I've never really heard of that before (I'll do some google fu!)   My specialist says my ligaments are really stretched, and if I don't actively hold my left shoulder into place (or sit/lay in a specific way) it falls out of it's socket. It sucks. I couldn't imagine having more than just my shoulder do that. :/ And damn. I don't have two years! Should have gotten on this sooner, I guess. I plan to talk to my doctor and specialist about getting all my medical records in order, so when I DO finally get to talk to someone, I'll have it all right there. And yeah, fatasses don't realize what type of "privilege" they really have.
