Chilblains (Perniosis) synonyms

Chilblains, also known as perniosis, are a common condition characterized by the inflammation of small blood vessels in the skin. This condition typically occurs in response to cold temperatures and affects the extremities, such as the fingers, toes, ears, and nose. Chilblains can cause discomfort, itching, redness, and swelling in the affected areas.

Synonyms for chilblains include:

• Frostbite: Although frostbite and chilblains share some similarities, they are distinct conditions. Frostbite occurs when the skin and underlying tissues freeze due to prolonged exposure to extreme cold.


• Perniosis: This is the medical term for chilblains and is often used interchangeably.


• Chill burns: This term is sometimes used to describe the burning sensation experienced in the affected areas due to chilblains.


• Winter sores: Chilblains are more common during colder months, hence the term "winter sores."


• Chilblain lupus: In some cases, chilblains can be associated with lupus, an autoimmune disease. This term is used when chilblains occur as a symptom of lupus.

It is important to note that chilblains are not caused by freezing temperatures alone, but rather by the body's abnormal response to cold. Factors such as poor circulation, tight footwear, dampness, and certain medical conditions can increase the risk of developing chilblains.

To prevent chilblains, it is recommended to keep the affected areas warm, avoid sudden temperature changes, wear appropriate clothing in cold weather, and maintain good circulation through regular exercise. If chilblains persist or cause severe discomfort, it is advisable to seek medical attention for proper diagnosis and treatment.

Remember, taking care of your skin and protecting yourself from extreme cold can help prevent the occurrence of chilblains and ensure your overall well-being during colder months.
