The fact that hives become more serious after improving immunity may be caused by hyperimmunity, which makes the body more sensitive to external stimuli. Excessive immune function is an imbalance in the immune state, for example, some people do not react to contact with allergens, but when people with excessive immune function come into contact with them, the immune system reacts with a high degree of sensitivity, resulting in allergic symptoms and the manifestation of urticaria. If urticaria still occurs even after the immunity has been improved, it is recommended to go to the hospital for allergen testing, and avoid contact as much as possible after clarifying the allergens, which can effectively prevent the recurrence of urticaria. In addition, it is recommended to take immunomodulators under the guidance of a doctor for treatment, such as splenic peptide oral lyophilized powder, thymosin and so on, but do not blindly use the drug, so as not to cause adverse reactions.
