Papular urticaria is a type of allergic reaction, mostly related to contact with irritants or bites from mosquitoes, fleas, and similar insects. Typically, it causes red wheals to appear on localized areas of the body, often topped with a small secondary lesion or blister. Most cases involve itching. Generally, papular urticaria can resolve on its own within about a week without treatment. However, if the symptoms are severe, and the blisters are large, scratching them open can lead to infection, which will prevent natural healing. It is best to treat papular urticaria as soon as it appears using antiallergic medications either topically or orally, which usually lead to a quick recovery. After recovery, it is crucial to maintain a proper diet and lifestyle habits, avoid keeping small pets at home, stay away from areas with dense vegetation, and ensure bedsheets and covers are sun-dried to sterilize and kill germs.
