If you’ve spent a chilly afternoon outside and come back to find your toes looking like angry, purple grapes that itch like crazy, you’ve likely met Chilblains. While the name sounds like something out of a Victorian novel, they are a very real (and very annoying) winter foot condition. In medical terms, we at My Chicago Foot Expert call them perniosis, but Chilblains is easier to remember because it sounds, well, chilly.
So, what exactly is happening to your feet, and should you visit the podiatrist?
What Are Chilblains?
Chilblains are essentially a glitch in how your body handles temperature changes. When your skin gets cold, the tiny blood vessels near the surface constrict to keep your core warm. When you warm up again, those vessels are supposed to expand.
But in people who get chilblains, the vessels don’t expand quite right. Instead, they leak blood into the surrounding tissue, which creates a localized inflammatory response.
What Do Chilblains Look Like?
You’ll know them when you see them. Unlike a normal frostbite, chilblains are small, red, blue, or purple bruised bumps on the tips of the toes or the heels. Your toes may also be swollen and itch, and burn while thawing out, especially when you get close to a heater.
In severe cases, small blisters or even shallow sores can form on the surface.
Are Chilblains Dangerous?
Here is the good news: for most healthy people, chilblains are not dangerous. They are a self-limiting condition, meaning they usually clear up on their own in one to three weeks, as long as you stay warm.
However, they can become dangerous if the skin breaks. Because circulation in the area is already compromised, a broken chilblain is a wide-open door for an infection. If you see yellow discharge, spreading redness, or if you have a fever, that’s a major red flag.
Do Chilblains Require Treatment?
Most of the time, the treatment is just patience and heat management. But you should see a podiatrist if:
- You have Diabetes or Poor Circulation: If your blood vessels are already damaged, chilblains can turn into non-healing ulcers.
- They Keep Coming Back: Frequent chilblains can be a sign of an underlying connective tissue disorder or a blood pressure issue.
- The Pain is Unbearable: We can prescribe topical creams (like nitroglycerin or corticosteroids) that help open those stubborn blood vessels and stop the itch.
The #1 rule for chilblains? Don’t scratch! You’ll damage the skin further. Keep them dry, keep them covered.
