Cold Weather Skin Conditions: Frostbite, Raynaud's Phenomenon, and Pernio
During the winter months, I hear a lot of concern from patients about frostbite. Frostbite is a very real danger in extremely cold weather. However, patients often confuse other dermatological conditions – such as frostnip, Raynaud’s phenomenon, and pernio – with frostbite. I hope to clear up some of the confusion by explaining these conditions here.
