From few days facing sensation and Pain on Arm pit rib near chest and Back side of shoulder. Little sensation with some time feel like current shocks in the areas. Normal working is ok but feel pain with spill when lay more than 10 minutes Consulting with neurology and General physician. But every one said it's ok and gives medicine. But when ever I slept on the same side pain gets started. On Rib and muscle there is no problem until unless if I can't move. Already Taking B12 and Vitamin D
