 [ Symptoms ] Which medicine to take if I get a Frost bite? [ Disease ] 1)Get out of the cold. Once you're in a warm space, remove wet clothes and wrap up in a warm blanket. 2) Gently rewarm frostbitten areas. Soak frostbitten fingers, toes or other extremities in warm water â€” 105 to 110 F (about 40 to 43 C). If a thermometer isn't available, test the water by placing an uninjured hand or elbow in it â€” it should feel very warm, not hot. Soak for 20 to 30 minutes or until the skin becomes its normal color or loses its numbness. For the face or ears, apply a warm, wet washcloth.
