Yes, Cervical Dystonia. No, not related to spine injury. Mine is Genetic. I have not experienced pain all over my body. Yes, I have diarrhea from Microscopic Colitis, but that's a whole nother issue. My pain is the neck. We used to be called the "Pain in the Neck Ladies" in my support group. Yes, my mouth gets tight as a Tic along with pain. It sucks when you know more about this disease than your neurologist. I ask again, what are they teaching in medical school?
