The difference between papular urticaria and urticaria

Papular urticaria is an allergic reaction caused by direct contact with irritants or insect bites such as mosquitoes. The cause of the disease is relatively accurate, and treatment typically involves disinfecting clothes, bed sheets, and duvet covers by exposing them to sunlight, avoiding contact with small animals, and common antiallergic medications can cure it quickly. The causes of common urticaria are more complex and often unclear; identifying the allergens usually requires allergy tests in hospitals, and the treatment is more complicated than that for papular urticaria. Common antiallergic drugs can cure it in the short term. However, some cases of urticaria that enter a chronic phase can be very troublesome to treat, with lengthy treatment times and poor outcomes.
