Papular urticaria is mostly related to contact with irritants or direct bites by mosquitoes. Generally, it is a type of allergic reaction. In most cases of papular urticaria, red papules appear on the surface of the skin, which are quite itchy. It is okay to bathe during this period, but some papular urticaria shows clear small blisters on the reddened skin surface. It is best to avoid bathing during the period when these blisters are present. Bathing can easily burst the blisters, leading to infection. This condition must be treated properly. Regularly sunning bed sheets and covers at home, avoiding contact with small animals, and staying away from places with many plants and trees are advisable.
