The inflammation is due to cold, damp weather that damages small blood vessels and nerves in the skin. People with poor blood circulation are especially prone to chilblains.
Tobacco increases the risk of chilblain, as it constricts the blood vessels.
A chilblain may cause aching, burning, and itching, especially when the body becomes warmer. Some children form ulcers that may leave scars after healing. Treatment includes warm, protective clothing and gentle warming of affected areas. Corticosteroid creams may help soothe the itching.
