How is urticaria caused

The first aspect: all kinds of factors lead to temporary inflammatory hyperemia and large amount of fluid exudation in the skin and mucous vessels. It can cause local edema damage. It occurs and subsides rapidly, with severe itching. May have fever, abdominal pain, diarrhea or other systemic symptoms. Sudden onset can be seen at any age.

The second aspect: insect bites: insect bites are still the main cause of the disease. Almost all patients with papular urticaria have been bitten by insects before their illness. The disease is an allergic reaction. Saliva and secretion after insect bites cause a series of allergic reactions, causing papular urticaria.

The third aspect: caused by food allergy: whether food allergy is the pathogenic factor of papular urticaria has been a controversial issue. Studies at home and abroad have shown that food allergy is a pathogenic factor of papular urticaria.
