What it is
Keeping hands and feet warm, avoiding sudden heat such as hot water bottles on cold skin, and not smoking help prevent them.
Chilblains that keep coming back, or happen outside cold weather, may need checking for circulation problems or other conditions.
Common signs
- Small red, purple or darker swellings on toes or fingers
- Itching and burning, especially after warming up
- Blisters or ulcers occasionally
How it is usually diagnosed
- Usually recognised by how they look
- Blood tests if they are severe or unusual
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- Photos of the affected areas with dates
- Any blood test results
Questions to ask your doctor
- Is my circulation OK?
- How can I prevent them coming back?
- Should I be checked for any other conditions?
When to get help right away
Call 112 or go to the nearest emergency department if you have:
- Signs of infection, such as pus, spreading redness or fever, especially if you have diabetes
