Chilblains

Chilblains, also known as pernio, are small patches of inflamed skin. They develop after exposure to air that’s cold or damp (but not freezing). Usually, chilblains form on your fingers or toes.

Chilblains are typically red, bluish or purplish. They may feel itchy, tender or painful.

Anyone can get chilblains, but people with a low body mass index (BMI) have a higher risk of developing them.

Babies can get chilblains as well if they’re not wearing proper clothing in damp or cold weather.

It can be frustrating to get tender, inflamed patches of skin when the temperature drops — especially on visible places like your hands. But know that there are steps you can take to try to prevent them. Your healthcare provider can offer medications, as well.
