I was told it is part of it

I was also told by my rheumatologist who diagnosed me that a lot of fibro patients grind their teeth when they slerp contributed to jaw pain and TMJ.

When I was at university, which was a long time ago, my jaw used to crack when I opened my mouth and it made a strange sound. Later I got my top teeth out and a plate in place. Problem gone. I think it was what I see others have called TMJ. I was under a lot of stress at university, so I am assuming that I either gritted or ground my teeth at night. Take my plate out a night. No grinding.

Tmj. I had one injection. Worked. But fybro still does not leave me alone. Hitting the mouth. Teeth and hair. Where is my armour?

Never really thought about it but now that u mention it I do seem to have jaw pain & tiredness & don't want to eat.
