Frostbite is treated by rewarming the affected tissue. This should be done slowly, as rapid rewarming can cause tissue damage. The affected area should be immersed in water that is between 104 and 108 degrees Fahrenheit. Pain medication may be given to help manage the discomfort associated with rewarming. After rewarming, the affected area should be kept elevated to help reduce swelling. If blisters or other skin damage occurs, they should be treated to prevent infection. In severe cases, surgery may be required to remove dead tissue. It is important to seek medical attention as soon as possible if you suspect you have frostbite.
