Chilblains are red or bluish itchy, painful lesions which can develop on fingers, toes and rarely ears, on exposure to damp & cold air.
Why do people get chilblains?
The cold air causes blood vessels in the skin to tighten, leading to decreased oxygenation and inflammation in the exposed areas. This condition is common in northern parts of our country due to harsh weather conditions in winters. While anyone can develop chilblains, females, smokers and patients suffering from peripheral vascular diseases are at a greater risk. Wearing tight fitting shoes or gloves in damp weather increases the chances of chilblains. Young children and babies can also develop these lesions if they are not dressed in appropriate clothing for winters.
