<unk>  is damage to the skin and underlying tissues caused by extreme cold.
A person with<unk>  on the extremities may also be subject to hypothermia (lowered body temperature). Check for hypothermia and treat those symptoms first.<unk>  is distinguishable by the hard, pale, and cold quality of skin that has been exposed to the cold for too long. The area is likely to lack sensitivity to touch, although there may be an aching pain. As the area thaws, the flesh becomes red and very painful.
Any part of the body may be affected by<unk> , but hands, feet, nose, and ears are the most vulnerable. If only the skin and underlying tissues are damaged, recovery may be complete. However, if blood vessels are affected, the damage is permanent and gangrene can follow. This may require removal (amputation) of the affected part.
Upon warming, it is common to experience intense pain and tingling or burning in the affected area.
