Chilblains, also called perniosis or blain, when occurring on the feet, is a medical condition that is often confused with frostbite and trench foot. Chilblains are acral ulcers (that is, ulcers affecting the extremities) that occur when a predisposed individual is exposed to cold and humidity. The cold exposure damages capillary beds in the skin, which in turn can cause redness, itching, blisters, and inflammation.[1] Chilblains are often idiopathic in origin but can be manifestations of serious medical conditions that need to be investigated. Chilblains can be prevented by keeping the feet and hands warm in cold weather. Smoking cessation and consultation with a dermatologist is advised.
With treatment, chilblains usually heal within 7–14 days.
