Gently re-warm the frostbitten extremity in luke-warm water (approx. 94F). As the extremity may be numb, be very careful about using warm and not hot water. Do NOT warm the extremity if there is a change it will re-freeze (e.g. you are still in an exposed position). Also, be advised that, if circulation returns, the results are quite painful. If possible, be prepared to treat for pain. Subsequent blackening of the exposed tissue indicates potential of necrosis, which may require amputation.
