Chilblains

What are chilblains?
These occur when the blood vessels supplying the skin react in an abnormal way to cold and damp. They are found most often on the backs of the heels and on toes.
They may look blue in colour and feel very cold, or else they may be feeling hot, red and throb or feel itchy.
