Papular urticaria is a type of allergic reaction, associated with direct contact with irritants, mosquito bites, or flea bites. It is important to frequently disinfect clothing, bed sheets, and quilt covers by exposing them to sunlight. Try to avoid keeping small animals at home, visiting parks or areas with abundant plants, or sitting or lying on grassy areas. Treatment should be carried out in a standard manner. Some papular urticaria lesions might develop small blisters at their apex, which should not be scratched or ruptured to prevent infection. If ruptured, the area should be disinfected with iodine and the local wound should be protected. Additionally, avoid spicy and irritating foods and try not to stay up late.
