May be urgent: If this is just developing at this very minute, you may be in the early stages of a severe allergic reaction ("Steven-Johnson Syndrome") which is a medical emergency. If this is acute, TO IMMEDIATELY TO AN EMERGENCY ROOM. If this is not acute, it still will require careful evaluation.
