Serious cases of frostbite have been known to kill and damage tissue to the extent that amputation is necessary. The extent of frostbite is best evaluated by a qualified medical professional.

How long does it take for frostbite to kill you?

Once the wind chill makes the temperature feel like –28 or colder, exposed skin can freeze in under 30 minutes. When it drops to –40, frostbite can occur in less than 10 minutes. Take it to –55, and you're in danger within two minutes.

Can you die from frostbite?

If frostbite is severe, the loss of blood supply to the tissue may cause it to die (gangrene). A type of surgery called debridement may be needed to remove the dead tissue. Amputation may be needed if frostbite is severe.
