Red or sore skin
iStock/jaim924 Common areas where frostbite occurs are the fingers, toes, cheeks, nose, ears, and chin. If any of these turn red, that’s a sign of frostnip, an early warning sign of frostbite. Frostnip doesn’t permanently damage the skin, but it’s a signal to seek warm shelter quickly. Another frostnip symptom might include the skin feeling very cold to the touch.
Prickling feeling, like “pins and needles”

(Because of the numbness, many people can’t tell when frostbite has set in. To avoid the condition worsening, pay attention to the color and texture of the exposed skin.)
