Preparing for an appointment
Chilblains (CHILL-blayns) are the painful inflammation of small blood vessels in your skin that occur in response to repeated exposure to cold but not freezing air. Also known as pernio, chilblains can cause itching, red patches, swelling and blistering on your hands and feet.
Chilblains usually clear up within one to three weeks, especially if the weather gets warmer. You may have recurrences seasonally for years. Treatment involves protecting yourself from the cold and using lotions to ease the symptoms. Chilblains don't usually result in permanent injury. But the condition can lead to infection, which may cause severe damage if left untreated.
The best approach to chilblains is to avoid developing them by limiting your exposure to cold, dressing warmly and covering exposed skin.
