more info on frostbite injury - from https://www.webmd.com/first-aid/frostbite
The doctor will collect data in order to classify the injury as superficial or deep and the prognosis as favorable or poor. A good prognosis is heralded by intact sensation, normal skin color, blisters with clear fluid, the ability to deform the skin with pressure, and the skin becoming pink when thawed. Blisters with dark fluid, skin turning dark blue when thawed, and an inability to indent the skin with pressure indicate a poor prognosis. from -- You received this message because you are subscribed to the Google Groups "massfire" group.
