Chilblains (/ˈɪlblnz/; also known as pernio and perniosis)[1] is a medical condition that occurs when a predisposed individual is exposed to cold and humidity, causing tissue damage. It is often confused with frostbite and trench foot. The cold exposure damages capillary beds in the skin, which in turn causes redness, itching, blisters, and inflammation.[2] Chilblains can be prevented by keeping the feet and hands warm in cold weather. Chilblains can be idiopathic, but may also be a manifestation of a serious medical condition that needs to be investigated. A history of chilblains is suggestive of a connective tissue disease (such as lupus). Chilblains in infants, together with severe neurologic disease and unexplained fevers, can be seen in Aicardi–Goutières syndrome, a rare inherited condition.

Signs and symptoms[edit]

Chilblains from excessively icing the feet

The areas most affected are the ears, earlobes, nose, and extremities (feet, toes, hands and fingers).

Duration[edit]

With treatment, chilblains usually heal within 7–14 days.

Treatment[edit]

Historical[edit]

The medieval Bald's Leechbook recommended that chilblains be treated with a mix of eggs, wine, and fennel root.[9]
