Perniones, also known as chilblains or pernio, is a condition in which the skin reacts abnormally to cold and humid conditions. Due to impaired blood circulation in the small blood vessels, painful, red to purple swellings develop on the fingers, toes, ears, or nose. The affected areas may itch, burn, and in some cases even develop blisters or sores. Perniones occurs mainly in winter and usually disappears on its own when the temperature rises.
Symptoms:
- Redness and swelling of the affected areas.
- Itching and burning sensation.
- Painful blisters and ulcers in severe cases.
- Changes in skin color to bluish or purple.
- Symptoms often improve when it gets warmer.
Causes:
The exact cause of perniosis is not fully understood, but it is associated with the reaction of blood vessels to cold temperatures. Factors that contribute to the risk of developing perniosis include exposure to cold, damp conditions, poor blood circulation, a family history of perniosis, and lifestyle factors such as smoking that can affect blood circulation.
Diagnosis:
The diagnosis of perniosis is usually based on symptoms and by excluding other conditions. A physical examination of the affected areas and a review of medical history, including exposure to cold conditions, are typical. Additional tests may be necessary to rule out other conditions in some cases.
Treatment:
Treatments focus on relieving symptoms and include avoiding exposure to cold, using medications such as ibuprofen or aspirin to reduce pain and inflammation, and in severe cases, prescribing topical steroids or vasodilators.
Self-Care Tips:
- Keep your body warm, especially the affected areas.
- Wear warm, insulating clothing and gloves in cold weather.
- Improve blood circulation by exercising regularly.
- Quit smoking to improve blood circulation.
- Avoid abrupt changes from cold to warm temperatures.
