Chilblains, also known as pernio or perniosis, is a condition that occurs in response to cold and damp conditions.

3. Causes & Risk Factors
Chilblains are caused by the skin’s abnormal reaction to cold temperatures, particularly when exposed to quick changes in temperature. Genetic factors, poor circulation, and lifestyle choices like smoking can increase the risk of developing chilblains. Individuals with a family history of the condition or those with poor dietary habits may also be at a higher risk.
4. Diagnosis
Diagnosing chilblains typically involves a physical examination by a healthcare provider. In some cases, blood tests or imaging studies may be conducted to rule out other conditions. Primary care doctors can often diagnose and treat chilblains, but individuals with severe or recurrent cases may be referred to a specialist.
5. Treatment Options
Treatment for chilblains focuses on relieving symptoms and preventing complications. Medical treatments may include topical creams, pain relievers, or antibiotics for infected wounds. Lifestyle changes such as wearing warm clothing, avoiding cold exposure, and quitting smoking can also help manage chilblains. Alternative treatments like herbal remedies or acupuncture may provide additional relief.
6. Prevention
Preventing chilblains involves staying warm in cold weather, avoiding rapid temperature changes, and protecting the skin from moisture. Public health recommendations may include wearing appropriate footwear and clothing, keeping extremities warm, and staying indoors during extreme cold spells.
7. Complications & When to See a Doctor
Severe complications of chilblains may include skin ulceration, infection, or permanent skin damage. Individuals experiencing severe pain, open sores, or signs of infection should seek urgent medical care. It is important to monitor chilblains closely and consult a healthcare provider if symptoms worsen or do not improve.
8. Living with the Condition
Managing chilblains on a daily basis may involve keeping affected areas warm, avoiding triggers, and protecting the skin from further damage.
