My mother had that and Collengen's disease, Raynods, Arthritis and Lupus. She said that the trick was to take the pain meds and stay busy to keep your mind off the pain. Also to keep moving as much as possible. The lupus made her muscles hurt, the fibro made her skin hurt, arthritis hurt her joints, collengens and raynods made her tendons and veins hurt. She always said that she each day her goal was to make it through that day. She hand pieced and quilted beautiful quilts but she'd get up and move around quite often.
