I've had fibro for a while, but have never experienced TMJ-like problems. However, a week ago my gums and teeth started to hurt..this pain spread to my whole jaw and now I can barely open my mouth and am in SO much pain. I'm wondering whether fibro or TMJ has anything to do with it, or if it's just referred pain from my inflamed gums? My gums look a bit inflamed, so I'm going to go to the dentist and see what s/he says. Is it possible for TMJD to come on so suddenly?????? Even the back of my tongue hurts..and my jaw is the most painful!!!! No painkillers are helping, and I'm not sure what to do. Do 90% of fibro sufferers really have TMJD???
