geladura

Frostbite is an injury to skin or other living tissue that is allowed to freeze, especially affecting the fingers, toes, nose, ears, cheeks and chin. Most often, frostbite occurs in the hands and feet, often preceded by frostnip, a paling or reddening of a body part as its blood vessels constrict that tingles, feels very cold, or simply feels numb. This may be followed by the clumsiness and white or bluish, waxy-looking skin that evidence full-blown frostbite. Swelling or blistering may occur following treatment. Complications may include hypothermia or compartment syndrome.

AI overview

Frostbite is an injury that occurs when skin or living tissue freezes, commonly affecting extremities like fingers, toes, and facial features, and can progress from initial numbness and pale skin to white or bluish, waxy-looking tissue. It matters because it can lead to serious complications such as hypothermia or compartment syndrome, and may cause lasting damage including swelling or blistering even after treatment.
