Pernio

Pernia is a painful inflammation of the small blood vessels of the skin, which manifests itself as a result of a rapid transition from low to high temperatures. Pernio can cause itching, red spots, swelling and sores on the limbs, big toes, fingers, ears and nose.

Pernio may heal on its own, especially during periods of warming weather The disease usually resolves on its own within 1-3 weeks, although it may be characterized by seasonal manifestations for years. Treatment is mainly with medicines and creams Although pernio rarely causes permanent damage, the disease can lead to an infection that can cause serious problems without medical intervention.

The best way to avoid developing pernia is to rarely go out in cold environments, dress warmly and cover exposed areas of the body.

The exact causes of Pernia are unknown A rapid transition from low to high temperatures may be the cause of the body's abnormal response, which manifests as pernio Rapid heating of cold skin causes rapid expansion of small blood vessels under the skin The surrounding large blood vessels cannot keep up with this process and as a result blood leaks into the tissues
