Chilblains Causes, Symptoms, Diagnosis and Treatment

Chilblains

What Is Chilblains?

Also called pernio, chilblains is a medical condition where individuals who are vulnerable to the condition experience swelling and blisters on their skin when exposed to humidity or cold weather.

Exposure to the cold can damage tiny blood vessels (capillaries) in the skin which then lead to exhibition of symptoms in an individual.
Although they rarely cause any permanent damage, chilblains can be highly uncomfortable and a source of agony for the affected individuals.

Moreover, if chilblains persist and are left untreated, they may lead to the development of infections. Infections, in turn, can cause severe damage if not promptly treated.

Avoidance to cold and humid conditions, wearing warm clothes and covering the affected skin and thereby shielding the skin from further harm normally cause the chilblains to disappear in a few weeks.

Causes Of Chilblains:

The definite cause of chilblains is yet unknown.

They are a result of an abnormal reaction to cold. The narrowing and widening of blood vessels when the skin is exposed to cold and heat respectively is a natural biological phenomena.

However, if this occurs too quickly, blood vessels near the skin are unable to handle the increased blood flow. This may cause blood to leak to the surrounding tissues, which in turn causes swelling and itchiness; symptoms associated with chilblains.
