Based on your signs and symptoms, the appearance of your skin, and a review of recent activities
in which you were exposed to cold, frostbite can be diagnosed.
To determine the severity of the frostbite
and to check if bone or muscle is damaged, tests such as an X-ray, bone scan or magnetic resonance imaging (MRI) test may be conducted.
Treatment for frostbite includes first-aid care and medical treatment.
- Check for hypothermia.
- Protect your skin from further exposure.
- Get out of the cold.
- Gently rewarm frostbitten areas.
- If there's any chance the affected areas will freeze again, don't thaw them.
