Chilblains, also known as perniosis, is a painful inflammatory condition that affects the small blood vessels in your skin when exposed to cold temperatures followed by rapid rewarming. This condition typically appears on the fingers, toes, ears, and nose during cold and damp weather. While chilblains are not usually serious, they can be uncomfortable and recurrent. Understanding the symptoms can help you identify the condition early and take appropriate preventive measures.
Most people experience chilblains during winter months, particularly in regions with cold, humid climates. The condition occurs when sudden temperature changes cause the small blood vessels under the skin to expand too quickly, leading to blood leakage into surrounding tissues. Recognizing the symptoms is crucial for proper management and preventing complications.
1. Red or Purple Patches on the Skin
One of the most distinctive symptoms of chilblains is the appearance of red or purple patches on affected areas of the skin. These discolored patches typically develop several hours after exposure to cold temperatures.
The discoloration occurs due to inflammation of the small blood vessels beneath the skin surface. Initially, the affected areas may appear bright red, but as the condition progresses, they can turn darker, taking on a purple or bluish hue. These patches are usually well-defined and can vary in size from small spots to larger areas covering multiple fingers or toes.
The intensity of the color change often correlates with the severity of the inflammation. In mild cases, you might notice only slight redness, while more severe cases can display deep purple or almost black discoloration. The patches are most commonly seen on:
- Fingers and toes
- Heels and the balls of feet
- Ears and earlobes
- Nose
- Other extremities exposed to cold
2. Swelling and Inflammation
Swelling is another prominent symptom that accompanies chilblains. The affected areas become noticeably puffy and inflamed, making the skin appear tight and stretched.
This swelling results from fluid accumulation in the tissues surrounding the inflamed blood vessels. The edema can make it difficult to bend fingers or toes comfortably, and you may notice that rings feel tighter or shoes become uncomfortable. The swelling typically develops within a few hours of cold exposure and may persist for several days or even weeks.
The degree of swelling can vary significantly between individuals and episodes. Some people experience mild puffiness, while others develop significant swelling that interferes with normal activities. The swollen areas may feel firm to the touch and can be tender when pressed. In severe cases, the swelling can be so pronounced that it affects mobility and functionality of the affected digits.
3. Intense Itching Sensation
Intense itching is perhaps one of the most bothersome symptoms of chilblains. The affected areas can become extremely itchy, particularly when you enter a warm environment after being in the cold.
This itching sensation can be relentless and may worsen at night or when the affected area is warmed. The urge to scratch can be overwhelming, but scratching should be avoided as it can damage the already compromised skin and lead to complications such as breaks in the skin or secondary infections.
The itching is caused by the inflammatory response in the tissues and the release of chemical mediators like histamines. Many people describe the sensation as:
- Burning and itching combined
- Prickling or tingling feelings
- An irresistible urge to scratch
- Intensification when warming up
The itching can be so severe that it disrupts sleep and daily activities, making chilblains particularly distressing for sufferers.
4. Burning or Prickling Sensation
A burning or prickling sensation in the affected areas is a characteristic symptom that many chilblains sufferers experience. This uncomfortable feeling is often described as pins and needles or a hot, stinging sensation.
The burning sensation typically intensifies when you move from a cold environment to a warm one, or when you try to warm up the affected areas. This happens because the sudden temperature change causes the blood vessels to dilate rapidly, triggering nerve endings in the inflamed tissue.
The prickling feeling can be constant or intermittent and may be accompanied by increased sensitivity to touch. Even light pressure from clothing or bedsheets can trigger or worsen the sensation. Some individuals report that the burning feeling is so intense it feels like the affected area is on fire, making it difficult to concentrate on other tasks.
5. Skin Tenderness and Pain
Tenderness and pain in the affected areas are common symptoms that can range from mild discomfort to severe pain. The skin becomes sensitive to touch, and even gentle pressure can cause significant discomfort.
The pain associated with chilblains has several characteristics:
- Aching or throbbing pain that may be continuous
- Sharp pain when touching or pressing the affected area
- Increased pain when bearing weight on affected feet
- Pain that worsens during temperature changes
Walking can become difficult when chilblains affect the toes or feet, as each step puts pressure on the tender, inflamed tissue. Similarly, when fingers are affected, gripping objects or performing fine motor tasks can be painful. The pain may persist for the entire duration of the chilblains episode, which can last from one to three weeks.
In some cases, the pain can be severe enough to interfere with normal daily activities, affecting your ability to work, exercise, or perform household tasks comfortably.
6. Blistering and Skin Changes
In more severe cases of chilblains, blisters may develop on the affected skin. These fluid-filled lesions appear as bumps on the surface of the red or purple patches and indicate a more serious inflammatory response.
The blisters can vary in size and may be filled with clear fluid or, in some cases, blood. When blisters form, the risk of complications increases significantly because:
- Broken blisters can create open wounds
- Open skin is vulnerable to bacterial infection
- Healing time may be prolonged
- Scarring becomes more likely
In addition to blistering, other skin changes may occur, including dry, cracked skin over the affected areas. The skin may also develop a rough, scaly texture as it heals. In chronic cases where chilblains recur frequently in the same location, the skin may undergo permanent changes, becoming thicker or developing persistent discoloration.
It’s important not to pop or deliberately break any blisters that form, as this significantly increases the risk of infection and can delay healing.
7. Cold and Clammy Skin
The affected areas often feel cold and clammy to the touch, even after you’ve moved to a warmer environment. This occurs because the compromised blood circulation in the affected areas prevents proper warming and temperature regulation.
The skin may feel:
- Unusually cold compared to surrounding areas
- Moist or slightly damp
- Different in texture from normal skin
- Slow to warm up even with external heat
This temperature difference can persist for hours or even days after the initial cold exposure. The clammy feeling is due to abnormal sweating in the affected area combined with poor circulation. You might notice that while the rest of your body has warmed up after coming indoors, your fingers or toes remain cold and uncomfortable.
The persistent coldness in the affected areas is not only uncomfortable but also indicates that the blood vessels are still not functioning normally, which is why gradual rewarming is important rather than exposing the area to sudden heat.
Main Causes of Chilblains
Understanding what causes chilblains can help you take steps to prevent their occurrence. The condition develops due to a combination of environmental factors and individual susceptibility.
Cold and Damp Weather Exposure
The primary trigger for chilblains is exposure to cold, particularly in damp conditions. When your skin is exposed to cold temperatures, the small blood vessels near the surface constrict to preserve body heat. If you then warm up too quickly, these blood vessels may not be able to open up properly, causing blood to leak into surrounding tissues and trigger inflammation.
Poor Circulation
Individuals with poor circulation are more susceptible to developing chilblains. Conditions that affect blood flow, such as Raynaud’s phenomenon, increase the risk. Poor circulation means that the blood vessels are less efficient at responding to temperature changes, making them more vulnerable to the damage that causes chilblains.
Low Body Weight
People with low body weight or low body fat have less insulation to protect against cold temperatures. This makes them more vulnerable to the rapid temperature changes that trigger chilblains, as their extremities cool down more quickly and thoroughly.
Hormonal Factors
Hormonal changes can influence the development of chilblains. Women are more likely to develop the condition than men, possibly due to hormonal influences on blood vessel behavior. Changes in hormone levels may affect how blood vessels respond to cold exposure.
Living Conditions and Lifestyle
Living or working in poorly heated environments increases the risk of chilblains. Repeated exposure to cold, damp conditions without adequate protection makes the blood vessels more susceptible to damage. Lifestyle factors such as smoking can also worsen circulation and increase susceptibility.
Genetic Predisposition
Some people appear to have a genetic predisposition to chilblains, with the condition running in families. If your parents or siblings have experienced chilblains, you may be more likely to develop them as well.
Prevention Strategies
Preventing chilblains is far easier than treating them once they develop. By taking appropriate precautions, you can significantly reduce your risk of experiencing this uncomfortable condition.
Keep Extremities Warm
The most important prevention strategy is to keep your hands, feet, ears, and other vulnerable areas warm in cold weather. Wear appropriate clothing including:
- Warm, insulated gloves or mittens
- Thick socks made of wool or thermal materials
- Well-insulated, waterproof footwear
- Hats or ear warmers
- Layered clothing to maintain core body temperature
Avoid Rapid Temperature Changes
When coming in from the cold, warm up gradually rather than exposing cold skin to direct heat sources. Avoid placing cold hands or feet directly on radiators, near fires, or under hot water. Instead, allow your body to warm up naturally at room temperature.
Maintain Good Circulation
Regular exercise helps improve overall circulation, making your blood vessels more resilient to temperature changes. Activities that get your blood flowing, even gentle exercises, can be beneficial. Avoid sitting or standing in one position for too long, especially in cold environments.
Keep Skin Dry
Moisture increases heat loss from the skin, so keep your extremities dry. Change out of wet socks or gloves immediately, and ensure your footwear is waterproof if you’ll be in wet conditions. Apply moisturizer regularly to prevent skin from becoming dry and cracked, which can increase vulnerability.
Avoid Tight Clothing
Tight clothing, footwear, or accessories can restrict blood flow to extremities, increasing susceptibility to chilblains. Ensure that your shoes, gloves, and socks fit properly without being constrictive.
Don’t Smoke
Smoking constricts blood vessels and impairs circulation, making you more vulnerable to chilblains. Avoiding tobacco products can improve your vascular health and reduce your risk.
Maintain a Healthy Weight
Maintaining a healthy body weight provides better insulation against cold and supports overall circulation. A balanced diet rich in nutrients that support vascular health can also be beneficial.
Frequently Asked Questions
How long do chilblains last?
Chilblains typically last for one to three weeks, though this can vary depending on severity and whether you continue to be exposed to cold conditions. In some cases, symptoms may persist longer, especially if the affected areas are repeatedly exposed to cold. With proper care and prevention of further cold exposure, most chilblains heal without complications.
Are chilblains contagious?
No, chilblains are not contagious. The condition is caused by your body’s reaction to cold exposure and subsequent rewarming, not by any infectious agent. You cannot catch chilblains from someone else or pass them to others.
Can chilblains lead to serious complications?
While chilblains are usually not serious, complications can occur if the skin becomes broken or ulcerated. Open wounds can become infected, which may require medical attention. Rarely, severe or recurrent chilblains can lead to permanent damage to the affected tissue. If you notice signs of infection such as increased pain, pus, spreading redness, or fever, you should seek medical advice.
Who is most at risk for developing chilblains?
People most at risk include those with poor circulation, individuals with low body weight, women (particularly of childbearing age), people with autoimmune conditions like lupus, those with Raynaud’s phenomenon, and individuals living in cold, damp climates without adequate heating. Smokers and people with a family history of chilblains are also at higher risk.
Can chilblains occur in warm weather?
Chilblains are primarily a cold-weather condition and rarely occur in warm weather. However, they can develop if you’re exposed to cold conditions even during warmer seasons, such as in air-conditioned environments, cold water, or at high altitudes where temperatures drop significantly.
Should I see a doctor for chilblains?
Most cases of chilblains can be managed at home with self-care measures. However, you should consult a healthcare provider if this is your first episode and you’re unsure of the diagnosis, if the symptoms are severe or persistent, if you notice signs of infection, if you have underlying health conditions affecting circulation, or if chilblains recur frequently. A doctor can rule out other conditions and provide guidance on management.
Can children get chilblains?
Yes, children can develop chilblains, particularly those who spend a lot of time outdoors in cold weather without adequate protection. Children may be more susceptible because they may not recognize when they’re getting too cold or may be less likely to wear appropriate protective clothing. Parents should ensure children are properly dressed for cold weather and check their extremities regularly for signs of chilblains.
Is there a difference between chilblains and frostbite?
Yes, chilblains and frostbite are different conditions. Frostbite is more serious and occurs when tissue actually freezes due to extreme cold exposure, potentially causing permanent damage. Chilblains develop from exposure to cold (but not freezing) temperatures followed by rapid rewarming, causing inflammation but not tissue freezing. Frostbite requires immediate medical attention, while most chilblains can be managed with self-care.
