Chilblains

Chilblains or pernio is a common form of cold injury that is often mistaken for frostbite. Frequently seen on the fingers, toes and ears, chilblains are reddish-blue and itchy. They form blisters. Chilblains involve formation of inflammatory skin lesions caused due to repeated intermittent exposure to cold and wet but non-freezing temperatures. Vascular inflammation and tissue bed hypoxia may develop and subsequently lead to permanent tissue damage. Children, elderly persons and those with impaired blood circulation are more prone to developing chilblains when exposed to cold and damp. Symptoms of chilblains are reddish skin and inflammation of toes and fingers. Keep yourself warm, especially during extreme changes in temperature. Some might gain relief on mild massage. Medicines to improve circulation are often prescribed.
