There are many reasons why children may develop hives, such as exposure to allergens, bacterial infection, or genetic factors. If children display symptoms of hives, parents must promptly identify the cause and treat the condition with medication based on the examination results. Normally, hives cannot heal on their own; not only are they unlikely to resolve without treatment, but they may also recur. If a child suffers from hives, it is best for parents to take them to the hospital for a detailed and comprehensive examination, and to follow the guidance of a professional doctor for safe and effective targeted treatment.
