Acute urticaria generally heals quickly if treated properly after onset. If the treatment is delayed or improper, and the disease is not completely cured within a month and a half, it automatically enters a chronic phase. Treatment in the chronic phase is more troublesome, requiring long-term medication. Therefore, once this condition is detected, it is crucial to seek formal treatment, avoid spicy and irritating foods, enhance exercise, strengthen immunity, and avoid buying and using medications arbitrarily, as this could complicate treatment if it becomes chronic. For severe cases of acute urticaria, if feasible, patients can also go to the dermatology department of a regular hospital for infusion therapy, which can speed up recovery. (Please use medication under the guidance of a doctor.)
