The description is consistent with the diagnosis of artificial urticaria, i.e. positive for artificial scratching, a type of allergic disease, mostly associated with low resistance. Artificial urticaria is manifested by the appearance of striated elevations along the scratch marks after a few minutes of scratching the skin with a hand or a blunt instrument, which mostly fade within half an hour, and at the latest not more than 24 hours, or a delayed form, which mostly appears a few hours after the irritation. The most definite feature is that it does not leave a trace after fading and is not fixed in position. The symptoms may persist for weeks, months or even years. In patients of several weeks, it may be related to a recent infection (e.g., cold, diarrhea, sore throat, etc.) or to poor rest and decreased resistance. In long-term patients, it may be related to a chronic medical condition such as H. pylori infection. The treatment of the disease is based on sequential therapy oral anti-allergic drugs, choose 1-2 anti-allergic drugs, control the disease and then gradually reduce the drug, find a minimum maintenance amount, and try to stop the drug after regulating the body with Yu Ping Feng granules and compound glycyrrhizin tablets. Commonly used anti-allergic drugs include levocetirizine tablets, loratadine tablets, etc. If the treatment is difficult, consider refractory urticaria, you need to improve allergen, thyroid ultrasound, thyroid function and other tests. Artificial urticaria patients should pay attention to early to bed and early to rise, appropriate exercise, do not eat irritating food, eat more high-quality protein such as lean meat, etc., to improve resistance and help early recovery.
