Itching on the body even after the hives have healed may be caused by factors such as the disease not being cured and recurrence. It is recommended to combine the doctor’s advice to continue to use medication, but also to find and get rid of allergens, to reduce the recurrence of urticaria. 1. The disease is not cured: urticaria is caused by the expansion of small blood vessels in the skin and mucous membranes and the increase in permeability, often manifested as wind, erythema with itching. After drug treatment, the wind, erythema may subside. If the disease is not completely cured, itching may persist. It is recommended to continue to use medication under the guidance of a doctor until the symptoms are completely eliminated. 2. Recurrence of urticaria: Allergic patients are exposed to allergens, resulting in urticaria on the skin. After urticaria is cured, if you contact, ingest or inhale the allergic substances again, urticaria will recur, and red spots and wind bumps with itching may appear on the skin. It is recommended that patients with urticaria go to the dermatology department of the hospital and be treated with antihistamines such as loratadine and levocetirizine under the guidance of the doctor. Desensitization therapy, if necessary, can reduce the recurrence of urticaria.
