Urticaria is commonly referred to as urticaria, rubella, bumps, or rash (similar in name to rubella, but not the same disease). It is a common skin disease. It is caused by various factors that lead to temporary inflammatory congestion of the blood vessels of the skin and mucous membranes with a large amount of fluid exudation. This results in localized edematous damage. It occurs and subsides rapidly, with severe itching. There may be fever, abdominal pain, diarrhea or other systemic symptoms. It can be divided into acute urticaria, chronic urticaria, angioneurotic edema, and papular urticaria. It is important to stay away from allergens and to choose professional medications, such as Stimcolin, to prevent the condition from worsening. Urticaria is a common vascular disease of the skin and mucous membranes caused by a variety of different reasons, clinically characterized by limited, temporary, pruritic flushes and clusters of skin and mucous membranes. The pathogenesis can be immunologic (most commonly IgE-mediated type I allergic reaction) or non-immunologic.
