Chilblains
An untreated chilblain may develop into frostnip. Frostnip freezes the outer layers of fingers, toes, face and ears.

If treated immediately, the injury is generally reversible. If not, the condition develops further into the dangerous frostbite.

Chilblains (sometimes misspelled as chillblains)
Chilblains is an inflammatory swelling to the skin of your feet, hands, face and ears, caused by cold exposure. In contrast to frostbite, the skin does not freeze, but may leave some permanent damage to the fine blood vessels. In instances where the affected areas become sensitive to cold, the symptoms return quickly after every exposure. The skin develops red pimples or patches and may itch, burn or sting. It can worsen to painful swellings and blisters. The preferred treatment is to gradually warm the affected area, as sudden rewarming aggravates the condition.
