My whole body from jaws, neck shoulders upper and lower arms under rib cage stomach tops of thighs buttocks back all over tighten up and start cramping even my hands feet. Big toes start first back and forth is how i know it starting. Brings me to tears. I cant seat stand lay down to get comfort. I rib rib cramped areas. Mostly my stomach. After the attacks of this maybe 24 hrs later I feel as if someone beat me up from inside out. If Im driving I have to stop. Get out lean over then try to walk if I can. People think Im having heart attack or something.Anyone??
