Urticaria is a skin disorder characterized by hives or wheals accompanied by itching. It is called chronic when it lasts 6 weeks or more.
It may be due to immune-related causes (allergies, autoimmune diseases, etc.) and others that are not (cold, exercise, etc.). In addition to hives and itching of the skin, it may be accompanied by swelling of specific areas of the body, such as the face and tongue.
Diagnosis is clinical, by interrogation and physical examination.
Treatment is based on antihistamines and corticosteroids.
