Chilblains, also known as Pernio
A medical condition in which damage occurs to capillary beds in the skin, most often in the hands or feet, when blood perfuses into the nearby tissue, resulting in redness, itching, inflammation, and possibly blisters.
It occurs most frequently when predisposed individuals, predominantly women, are exposed to cold and humidity.
Temperature-related chilblains can be prevented by keeping the feet and hands warm in cold weather and avoiding exposing these areas to extreme temperature changes.
First-line treatment includes avoiding cold, damp environments and wearing warm socks or thermal insulative anti-shear shoe liners.
Chilblains can be idiopathic (spontaneous and unrelated to another disease), but similar symptoms may also be a manifestation of another systemic medical condition that must be investigated. Related medical conditions include Raynaud syndrome, erythromelalgia, frostbite, and trench foot, as well as connective tissue diseases such as lupus or vasculitis.
The areas most affected are the toes, fingers, earlobes & nose.
