Urticaria is commonly known as wind clumps, rash clusters, wind bumps, rash lumps (similar in name to rubella, but not the same disease) and rice bumps. Urticaria is a common skin disease. It is caused by various factors resulting in temporary inflammatory congestion of the blood vessels of the skin mucous membranes with massive fluid exudation, caused by temporary dilation of microvessels, increased permeability, and infiltration of serum into the tissues, resulting in localized edematous damage. It occurs or subsides rapidly and has severe itching. There may be fever, abdominal pain, diarrhea or other systemic symptoms. It can be classified as acute urticaria, chronic urticaria, angioneurotic edema, and papular urticaria. Urticaria is a sudden, edematous, dome-shaped bump or patchy, light red or skin-colored “bumps” (pimples) of varying size and shape, often preceded by itching and appearing after local scratching. They may also appear after heat, cold, and strenuous exercise and subside within 2 to 24 hours without leaving a trace, and may recur. Some patients may have nausea, vomiting, abdominal distension, diarrhea, chest tightness and other discomforts. In serious cases, blood pressure may drop, and asphyxia may occur in those with laryngeal edema, so do not ignore the condition. 1, etiology search Carefully and carefully inquire about life history, disease history and course of disease, detect allergens, etc., not to miss any suspicious details, although the etiology is complex, but can start from common triggers.
