I have unrelentless rib pain and most recently very painful feet. Is this r/t FMS? My feet seem to do better when I am up and walking. But if I sit or especially after I "sleep" I can hardly walk. Pain is around my heals, on the exterior sides and ... really all over. Pain is very bad in AM when I have "flares". It comes and goes and but asts sometimes for weeks. Is this familiar to anyone?
