Causes Frostbite occurs when the skin and body tissues are exposed to cold temperature for a prolonged period of time. Hands, feet, noses and ears are most likely to be affected. Although anyone who is exposed to freezing cold for a prolonged period of time can get frostbite, people who are taking beta-blockers, which decrease the flow of blood to the skin, are particularly susceptible.
Frostbitten skin is hard, pale , cold, and has no feeling.
Check for hypothermia and treat those symptoms first. Frostbite is distinguishable by the hard, pale , and cold quality of the skin that has been exposed to the cold for a length of time. The area is likely to lack sensitivity to touch, although there is probably a sharp, aching pain. As the area thaws, the flesh becomes red and painful. If only the skin and underlying tissues are damaged, recovery may be complete.
