I've had trouble with grinding my teeth for many years and as a result have developed TMJD. I wear a splint (everynight without fail) and I used to take valium at night to relax myself and the jaw muscles. I try meditation when I'm extra stressed but I have no doubt that I still grind at night because I'm very sore in the jaws when I wake up. I've also spent 3 weeks in a pain rehab clinic learning pain management.
I too will be investigating Biofeedback - thanks AK.
Dx Fibromyalgia, CF, Severe TMJ, Osteopenia of lower spine, arthritis of L hip, bursitis of L shoulder and hip, GERD, Perimenopause and query RA. Deleting Dairy and sugar out of my diet was what set me on the road to recovery.
