What are chilblains?
Chilblains are small itchy swellings on the skin, which can become painful over time. They are a localised form of vasculitis, which is an inflammation of the blood vessels in the skin. They can look like red or purple discoloured areas of skin, and commonly affect the toes, soles of the feet and the backs of the heels.
If chilblains are left untreated, they can swell and dry out, leaving cracks in the skin that can expose the foot to infection.

What causes them?
Chilblains are caused by the skin’s abnormal reaction to cold. The tiny blood vessels in the feet and other extremities constrict and become narrow. In extreme cases, the surface of the skin may break and sores or ulcers can sometimes develop. When exposed to warmth, the blood vessel can’t handle the sudden expansion and fluid can leak into the surrounding tissue and cause swelling and irritation. Chilblains typically occur a few hours after being exposed to the cold.
How are they treated?
If you have recurring chilblains it is recommended that you see a podiatrist
