Urticaria is a difficult disease to treat, and it can be divided into acute and chronic. If hives are to be treated, the first thing is to distinguish the cause of the occurrence of hives, mainly by finding the allergen of hives, which can be identified in the hospital to identify the allergen that causes hives, and later to determine the allergen to be removed from contact. In addition, we can also use certain anti-allergy drugs, such as antihistamines. It is also important to pay attention to the usual diet, suggesting a light diet with more vegetables and fruits containing fresh vitamins, avoiding smoking and drinking alcohol, avoiding exposure to spicy and stimulating foods, and paying attention to regular activities and avoiding excessive mental tension.
