Chilblains (also called pernio) is a painful skin condition caused by abnormal reactions of small blood vessels in response to cold, damp weather. It commonly affects the fingers, toes, ears, nose, and heels, leading to redness, swelling, itching, and sometimes blistering of the skin. Although chilblains are not life-threatening, they can cause significant discomfort if left untreated.
What Are Chilblains?
Chilblains develop when exposed skin warms too quickly after being cold. This sudden temperature change damages the tiny capillaries under the skin, triggering inflammation and swelling.
Chilblains are more common in:
- Cold and humid climates
- People with poor circulation
- Individuals with low body weight
- Smokers
- Those with autoimmune conditions
- People who do not wear adequate winter protection
Common Symptoms of Chilblains
Symptoms usually appear within a few hours after cold exposure and may last for several days or weeks.
Typical signs include:
- Red or bluish-purple patches
- Burning or itching sensation
- Swelling and tenderness
- Tight or shiny skin
- Blistering or ulcers (in severe cases)
If chilblains crack or develop sores, there is a risk of secondary bacterial infection.
Who Is Most at Risk?
Certain individuals are more prone to chilblains:
- Children and elderly people
- Those with poor blood circulation
- People with diabetes or peripheral vascular disease
- Individuals with Raynaud’s phenomenon
- Women (more commonly affected)
How Are Chilblains Diagnosed?
Chilblains are usually diagnosed based on:
- Clinical appearance
- Patient’s history of cold exposure
- Recurring seasonal symptoms
In rare cases, blood tests may be performed to rule out underlying autoimmune or circulatory disorders.
Treatment of Chilblains
Home Care
Mild cases typically improve with simple measures:
- Keep hands and feet warm and dry
- Avoid sudden heat exposure
- Use moisturizing creams to prevent cracking
- Elevate affected limbs
- Stop smoking (nicotine restricts blood flow)
Medical Treatment
For persistent or painful chilblains, doctors may prescribe:
- Topical corticosteroid creams to reduce inflammation
- Nifedipine to improve blood circulation
- Antihistamines for itch relief
- Antibiotics if infection occurs
Prevention of Chilblains
Prevention is the most effective approach.
Tips to avoid chilblains:
- Wear warm gloves, socks, and insulated footwear
- Keep your skin moisturized in winter
- Avoid tight shoes or clothing that restricts circulation
- Warm up slowly after coming in from the cold
- Exercise regularly to improve blood flow
- Maintain a healthy body weight
When to See a Doctor
Seek medical advice if:
- Symptoms last longer than 2–3 weeks
- Severe pain or blistering develops
- Signs of infection appear (pus, fever, redness spread)
- Chilblains occur without cold exposure
Possible Complications
Untreated or recurring chilblains may lead to:
- Skin ulcers
- Chronic scarring
- Secondary infection
- Ongoing discomfort during winter months
Living With Chilblains
Most cases resolve naturally once warmer weather arrives. However, consistent winter protection and healthy circulation habits can greatly reduce recurrence and discomfort.
Final Thoughts
Chilblains may seem minor, but they can cause persistent pain and skin damage if neglected. Recognizing early symptoms, staying warm, and following preventive steps can keep your skin healthy throughout cold seasons. If symptoms become severe or repetitive, medical evaluation is essential to rule out underlying circulatory conditions.
