There are some things you can try to get rid of them yourself and stop them coming back.

- take paracetamol or ibuprofen to ease the pain

- put your feet or hands on a radiator or under hot water to warm them up
- smoke or have drinks that have caffeine in them – this can affect the flow of blood in your fingers and toes
- scratch or pick at your skin
Causes of chilblains
- 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 from 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 or swelling.
