Chilblains, also known as pernio, is a medical condition that occurs when small blood vessels in the skin are constricted by cold weather, or other environmental triggers. This can lead to pain, inflammation, redness and itchy patches in the affected area. While there is no cure for chilblains, in most cases, chilblains clear up on their own, however, there are steps you can take to help manage the symptoms. By understanding what chilblains are and how to treat them, you can reduce your risk of developing them.
Causes Of Chilblains
One of the main causes of chilblains is exposure to cold weather. When the skin is exposed to cold temperatures for an extended period of time, the small blood vessels in the fingers and toes can constrict. This makes it difficult for the blood to circulate properly and can lead to the development of chill blains.
Another common cause of chilblains is sudden changes in temperature. If the skin is exposed to a very cold environment, and then suddenly warms up, and in the case of chilblains, too quickly, blood rushes to the blood vessels. The vessels can then become enlarged and cause inflammation. Many people first notice patches on their fingers and toes. The skin can have a sensation of burning, or feeling itchy. This can be very painful and can take several days to resolve.
Some medical professionals have suggested that the increased blood supply leaks into nearby tissue and this results in the swelling. This swelling then irritates the nerves in that area and results in a painful sensation.
There are some factors that may increase the chances of getting chilblains at different stages of your life. These include…
• having poor circulation
• weighing approximately 20% less, or more, than the healthy weight range for your height
• clothing that is too tight
• clothing that exposes the skin to cold conditions
• smoking and
• living in damp and cold conditions.
Certain medical conditions can also increase your risk of developing chill blains. These conditions include Raynaud’s disease, diabetes, and circulatory problems. If you have one of these conditions, it is important to take extra precautions when spending time in cold weather.

Symptoms of chilblains include a…
• burning sensation
• itchy skin
• blisters and
• sometimes, the skin on the hands and feet look shiny.
If you think you may have chilblains, it’s best to speak with a doctor. They can usually diagnose the condition with a physical examination. In some cases, they may also need to order tests if other symptoms are present.
In most cases, chilblains will heal on their own over time, usually within a few weeks. In most cases, as the skin starts to warm, the symptoms become less prevalent and improve over time.
However, if you are experiencing persistent itching, a doctor may be able to prescribe a topical ointment, such as corticosteroid cream, to help reduce inflammation. A doctor may also prescribe blood pressure medication to help the blood vessels open up more to prevent further occurrences.
If you have diabetes, or poor circulation, you are more likely to experience recurrent chilblains, and they may not heal as well. In these cases, it is best to seek medical attention to ensure that the chill blains do not worsen.

Chilblains can be a frustrating condition to live with, especially if they occur frequently. However, there are some things that can be done to help manage the symptoms, like…
- Warming the area slowly. It is important to do this slowly, as applying direct heat and quickly can make the condition worse. Try placing a blanket over the affected area to provide gradual warmth.
- As the skin becomes swollen and irritated, it may also be dry and itchy. Apply an unscented lotion on the area to keep it moisturised – this will also help to alleviate any itching.
- Avoid caffeinated drinks. Drinks with caffeine in them can affect the blood flow to fingers and toes.
- Avoid massaging the area. It can be tempting to massage the area to help get the blood flowing. However, this can do more harm than good. Rubbing can increase irritation and inflammation and make it more uncomfortable.
As chilblains can be uncomfortable and painful, the NHS has highlighted that you can take paracetamol, or ibuprofen, to ease the pain. Ask your local pharmacist for the best options.
If chil blains are particularly troublesome, speak to your doctor about possible treatments. There may be medications, or other therapies that can help lessen the effects of this condition.

While chilblains is a common condition, some other causes of this ailment may affect your health. One condition is Raynaud’s, which affects the blood supply to the extremities. The leading causes of this are stress and temperature changes.
For anyone living with Raynaud’s, Scleroderma & Raynaud’s UK is a charity organisation that is dedicated to supporting and improving the lives of people affected by both conditions. They also have an informative resource on chil blains there.
