This reduces the blood supply to the skin. As a result, skin tissue freezes and dies. Skin can also freeze to the surface of a metal object. Health problems that reduce circulation or weaken the body increase the risk of frostbite. Never massage or rub frostbitten areas and do not apply any ointments.
Treatment varies with the type of frostbite.
Burning, itching or peeling may occur. The nose, ears, hands, or feet are usually affected. Getting out of the cold and gradually warming the area are the treatments. If frostnip is not treated, the affected area will become red, swollen, and painful. In severe cases of frostbite, the skin turns blue or black, and the pain disappears.
