I have FM, Hypothyroidism(Hashimotos Autoimmune Disease), CFS/ME, G.A.D., Heart Disease, Vertigo... I experience what I call electric zaps on the left side of my head along my brain area, and I experience involuntary head movements (similar to parkisons) especially when my pain seems to get worse in my body and fatigue grows stronger. Does anyone have any idea what may be causing these
