Dr. Dennis Perry at McLaren Greater Lansing says we all should know how to prevent frostbite.
He says you may not notice anything wrong at first, because the affected area will be numb.
There are three degrees of cold injury: They include "frost nip" which affects the face, ears or fingertips, and doesn't lead to permanent tissue damage. "Superficial frostbite" -- which affects the outer skin. And "deep frostbite" -- which damages the underlying tissues. The skin may look white, grayish-yellow or even black. Blistering is also common.
To treat frostbite, get out of the cold and remove wet and constrictive clothing and jewelry.
If you think you have it, visit a doctor or go to the hospital emergency room as soon as you can.
Do not use direct heat from sources like heating pads, radiators or fires.
You can avoid frostbite altogether by limiting time outdoors in very cold, wet or windy weather.
Dress in layers of warm clothing and wear wind and waterproof outer garments.
