Phenotype: chilblains/perniosis, have you ever had them, yes/no

Chilblains — also known as perniones, chill burns, and perniosis — 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. Damage to capillary beds in the skin causes redness, itching, inflammation, and sometimes blisters.
