Children’s papular urticaria does not have the so-called rapid self-healing method, need to take general treatment as well as medication to improve. Pemphigus urticaria is mainly a localized allergic reaction caused by bites of insects, lice, mites, etc., or food and drug allergies, and is closely related to one’s own constitution. Those who are more sensitive have more severe allergic reactions. If you are bitten by a tick and its mouthparts stay in the skin, you need to consult a doctor in time and have them surgically removed. In general, you should pay attention to avoid the environment of insect bites and strengthen environmental hygiene. It is also necessary to avoid medications or foods that cause allergies. Oral anti-allergy drugs such as loratadine and cetirizine can be used, and topical ointments such as mupirocin are needed for localized infections. After the occurrence of papular urticaria in children, it is recommended to consult a doctor in a timely manner, and follow the doctor’s instructions for scientific use of medication, not unauthorized use of drugs.
