The first is FROSTNIP. This is where the skin freezes and becomes red, white and painful. Warming frostnip can be done by getting the patient to put her fingers under her arms.
FROSTBITE is more serious and an EMS Medical Emergency. This is where the body’s tissues, muscles, and vessels freeze. With frostbite, re-warming should only be attempted slowly using water no more than 40 degrees. Never rub or massage frostbitten areas; the re-warming process is usually very painful.
