Pain is often painful. As Frostbite develops, the skin becomes white or grayish yellow and appears and feels waxy and firm. Skin feels very cold and numb. Blisters may form. Often victims are not aware of Frostbite until others notice the symptoms.
Affected areas become blotchy red, swollen, and painful on re-warming.
While outside, cover the frozen part with extra clothing or warm cloth. If the hand or fingers are frostbitten, put the hand under the armpit for warmth. DO NOT rub the frostbitten part with snow or anything else. Bring victim inside promptly. The frostbitten area must be re-warmed rapidly.
