Hi everyone, I could sure use some big brains to help me with this issue. I don't know how to describe what happens to me at night, but I will try: I wake up multiple times (5-20) in a full-body FLEX. All my muscles are tense, rigid and hard. My back is arched, my arms are fully tensed, my hands are gripped in fists and -the worst- my jaw is clamped down so tightly that it takes monumental effort and concentration to release it. I have broken teeth because of this - even though I wear a night guard. I have thrown my neck out so badly from these spasms, that I have been immobilized for days (I have a history of hypermobility, degenerative discs and acute sprains in my cervical spine). This morning, my jaw aches, my head aches, my back is tweaked, my neck is sore, and my teeth are sore and feel almost loose - like there was immense pressure exerted on them for a long time. My only meds are T3 and T4, which I took years before ME. I was off all supplements for three months recently and, stupidly didn't notice if I had any reprieve from this issue (I do think it was better, though). Now I'm back on B vitamins, zinc, magnesium and a new Metagenics shake with a ton of stuff in it - but these spasms were definitely happening long before I ever took it. Does anyone have any idea what could be causing it or what could help it? I would really appreciate the help before I lose all my teeth, pop my shoulders out of joint or break my neck. Thank you!
