Chilblains are small, itchy, red patches that can appear after you have been in the cold. They usually clear up on their own. You may need to see a GP if they don't go away.
Chilblains usually appear a few hours after you have been in the cold.
You mostly get them on your fingers and toes. But you can get them on your face and legs, too.
Chilblains usually go away on their own in 2 to 3 weeks.
There are things you can try to:
A GP will check where it hurts to see if you have chilblains.
They may need to refer you for further tests with a specialist if they're not sure why you're getting chilblains.
Rarely, your GP will prescribe a medicine that can help your chilblains clear up.
You can get chilblains when it's cold. The cold makes the tiny blood vessels in your fingers and toes get smaller. This stops blood moving around as easily.
If you warm up too quickly, the blood vessels get bigger again and blood rushes to your fingers and toes. This can cause pain, redness and swelling.
