I have no answer because I am looking for the answer too. Same symptoms. Skin feels like sunburn and itches, and hurts on surface and subcutaneously. Pain wraps around torso; abdomen, ribs, back. No rash, no redness. Have had this steady for five weeks. Began suddenly. Neither improving nor worsening. Never lets up, but pain increases when jolted from taking steps or riding in car.
