Frostbite develops when the fluid inside skin and tissue cells freezes and crystallizes. This blocks the blood flowing to the area, causing tissue damage. Frostbite can occur in the feet, toes, nose, ears, hands, and fingers. During its early stages, the skin will turn red and it will sting, burn, or feel cold. As time passes, the skin may discolor to a yellowish gray or white, and it may turn waxy. It may also throb, swell, or become numb.
