That's a long list Ok... one thing at a time?) See a specialist dentist for your TMD. A good splint will do wonders for the pain... if it's more severe, then you'll need surgery too. The tinnitus could be from the tmd...

How much of your list can be placed under RA and how much under fibromyalgia? Perhaps do that kind of a balance sheet will help you look at it differently?

I've heard, but not yet studied, that fibromyalgia, being an auto immune disorder, can be improved or eliminated by diet... sure would be nice, I guess.

Your candida can be diet also, and or allergy (which can also be sinus, fibro etc.) and your memory loss can be improved with good diet too...

The overdoing part? Yeah, you must pace yourself. Life becomes a toss up... do you do something you really want to do, and pay the price later (all up-front knowing) or pass? It is really hard to stop while you're still feeling ok.
I don't have fibro but CMP... I don't wear any braces or splints when physically doing something, to help me stop sooner and not suffer. Of course, lately, I haven't done anything really physical...just can't pay the price

It's a tough long haul from the looks of it... I continue to attack my "list" ...

((((hugs)))) What do you want me to say now?
