Signs of frost bite

Answer 1

manifestations for superficial frostbite present as a white, waxy, soft, and numb appearance of the injured area while it is still cold. As thawing occurs, the area becomes flushed, edematous, and painful, and may become mottled and purple. Within 24 hours, large blisters form and remain for about 2 weeks before turning into a hardened eschar, which separates in about a month. As the eschar separates, it leaves painful, sensitive new skin that often sweats excessively. In deep frostbite, the injured part remains hard, cold, mottled, and blue-gray after thawing; edema forms in entire limb and may remain for months. Blisters may or may not form weeks after the injury. After several weeks, dead tissue blackens and sloughs off and a line demarcates dead from live tissue.

Answer 2

Frostbite makes the skin go numb and turns it completely black in really bad cases. It looks like you have a black boot on and that the skin is being ate away.
