It's the deeper frostbite, Sallis says, that concerns physicians, and that's not likely to occur at a game or while out skiing or running. That is the frostbite of lore, where gangrene can set in at a later time. But clinically, Sallis writes, the line between what's damaged, or gangrenous, and what's OK may not be determined for weeks or months after the injury. As with hypothermia, rewarming is the first line of defense. Any blisters that form should be treated gently, and not touched.
Infection is always a concern.
That's where most of the problem develops. Proper clothing or gear is the best prevention. Skiers, for instance, need goggles because the wind chill factor can freeze the corneas. Stay dry, and seek warm shelter if you start to feel deep tingling or pain. All rights reserved.
