Papular urticaria is a type of allergic disease, generally with mild symptoms. It manifests as red wheals with small blisters on top. Most cases do not require treatment and will subside gradually over time. It is advisable not to scratch these small blisters as breaking them can lead to infection. It is recommended to frequently expose clothes, bed sheets, and quilt covers to the sun for disinfection to eliminate mites or insects. Avoid contact with small animals and places with abundant flowers, plants, and trees. Also, avoid spicy and irritating foods and do not stay up late. Typically, conventional medications can completely cure the condition within about a week. Paying attention to diet and lifestyle habits is generally sufficient.
