This syndrome is not limited to the feet. Any skin area, usually an extremity, that is subjected to damp exposure may be affected. Pale, wrinkled skin is a symptom that indicates the need for complete drying out before underlying tissues begin to break down. Once damage to underlying tissues begins, immobilization may occur and recovery is prolonged, with some cases requiring one month or more depending on the extent of damage. Severe cases have required amputation.
Frostbite occurs from exposure to ambient or windchill temperature below freezing.
The time of exposure varies from instantaneous to several hours depending on the temperature, wind velocity, humidity, and protective measures taken. The most frequently affected parts of the body are the cheeks, nose, ears, chin, forehead, fingers and toes. Permanent tissue damage may result and excision or amputation of the affected area may be required. Hypothermia is the general cooling of the body's core temperature. It usually results when a person, who is not adequately clothed, is exposed to a cold, windy and possibly even wet environment for an extended period of time.
