Chilblains (perniosis) are itchy, painful, red or purplish bumps on the skin, usually fingers or toes, caused by an abnormal reaction to cold, damp, but not freezing, temperatures that cause small blood vessels to swell and leak. They appear after exposure to cold and rewarming, leading to burning, swelling, and sometimes blisters, typically resolving in weeks but prone to recurrence in cold, humid conditions.
It's caused by exposure to damp air that's cold but not freezing. Symptoms may show up a few hours after being in the cold. Chilblains can be prevented by limiting your time in the cold, dressing warmly and covering exposed skin. If you do get chilblains, keeping the skin warm and dry can help ease the symptoms.
Chilblains symptoms usually clear up in 2 or 3 weeks after cold exposure. In the meantime, try the following tips to ease your symptoms: Rewarm the skin slowly and gently, without massaging, rubbing or applying direct heat. Avoid cold exposure whenever possible.
Raynaud's disease is a systemic condition meaning it is often unpreventable, while chilblains are a physical response to cold. While chilblains can often be prevented with proper care and protection from the cold.
Chilblains appear as bluish or red patches on the skin. They may be hot, swollen or itchy. Normally they last for two to three weeks but this may be longer in people with poor circulation.
Conditions that may present with a similar clinical picture to chilblains include: Connective tissue disorders in particular lupus erythematosus and sarcoidosis (lupus pernio). Chilblain lupus erythematosus is a form of cutaneous lupus that presents with similar clinical features to idiopathic chilblains.
Wear woolen or thermal socks or tights or else wear several thin layers for extra warmth for example thermal leggings. Invest in thermal underwear and use loose woolen bed socks at night if necessary. DO NOT put your feet onto direct heat - for example on a hot water bottle or radiator.
Chilblain lupus erythematosus(CHLE) or Perniosis is a rare and chronic form of lupus involving the toes, fingers, nose, and ears precipitated by cold exposure. The prevalence is 3-20%, affecting mostly women and can be divided into primary and secondary.
The most common symptoms are episodes of coldness, numbness, and tingling in the fingers or toes. Affected digits develop pallor, and sometimes have sequential skin colour change from white, to blue, to red. Primary Raynaud's phenomenon (syn.
See a GP if:
you have chilblains and your skin has not got any better after 2 to 3 weeks. there is pus coming out of your skin. your temperature is very high, or you feel hot, cold or shivery. you keep getting chilblains.
Do not scratch the skin, as it is easily broken and can become infected. If chilblains break, cover with a dry sterile dressing. Keep active as this helps the circulation flow to the legs, feet and arms.
Here are a few for you to try:
Even simple foot exercises, like wiggling your toes or taking short walks, can make a big difference. Medication – In some cases, your doctor may prescribe medications to improve circulation, such as nifedipine. This is particularly common for people who have recurring or severe chilblains.
Some at-home remedies that may ease pain and swelling from chilblains include:
While cold extremities are commonly dismissed as normal occurrences that aren't cause for concern, frequent coldness in the feet can potentially be a sign of an underlying health condition, such as peripheral artery disease (PAD), which can affect circulation in the limbs.
If seen by a podiatrist immediately, chilblains will heal within seven to 14 days. If left untreated, however, there is a risk of complication, including skin ulceration, cracked or broken skin, and infections.
Raynaud's disease is a disorder of the blood vessels, which narrow when the person feels cold or stress, and affects the toes and fingers. People with this problem are more likely to get chilblains.
Lifestyle changes that improve circulation
Consider making changes such as: Exercise: Activities that keep you upright and moving — such as walking or jogging — encourage blood flow. Compression socks: The gentle pressure of compression garments helps blood move back toward your heart and decreases swelling.
During an attack of Raynaud's, affected areas of the skin usually first turn pale. Next, they often change color and feel cold and numb. When the skin warms and blood flow improves, the affected areas may change color again, throb, tingle or swell. Raynaud's most commonly affects fingers and toes.
Early warning signs of lupus often include extreme fatigue, unexplained fever, joint pain/swelling, skin rashes (especially a butterfly-shaped one on the face), hair loss, mouth sores, and Raynaud's phenomenon (fingers/toes turning white or blue in the cold). Because these symptoms mimic other conditions, lupus can be hard to diagnose early, but they often come in waves (flares) and affect various body systems.
The "worst" autoimmune diseases are subjective but often cited for severity, impact on life expectancy, or organ damage, with top contenders including Giant Cell Myocarditis (highly fatal), Vasculitis (damages blood vessels), Systemic Lupus Erythematosus (Lupus) (multi-organ), Multiple Sclerosis (MS) (nervous system), and Type 1 Diabetes (pancreas, life-long management). Other severe conditions include Scleroderma and Myasthenia Gravis.
Early signs of scleroderma often involve the hands and fingers, with Raynaud's phenomenon (fingers turning white, blue, or red in the cold), swelling, stiffness, and skin tightening or discoloration (shiny, lighter, or darker patches) being common. Other initial symptoms can include fatigue, joint pain, heartburn, and dry, itchy skin, with changes sometimes appearing as reddish patches or lines of thickened skin (morphea/linear scleroderma).
Woolly tights or thicker soled shoes can also help keep your feet warm. You could wear a couple of pairs of thin socks and several thin layers of clothing – this traps air and helps to keep you warm all over.
Athlete's foot, also called tinea pedis, is a skin infection caused by fungi. It usually starts between the toes. The condition can occur when feet get hot and sweaty inside closed shoes. Signs and symptoms of athlete's foot include an itchy, scaly rash.
Chilblains appear as reddish-purple bumps or patches on your skin. Chilblains can appear quickly, most often on your fingers or toes.
