Wind bumps, also called hives, are caused by allergies. Most of them will be accompanied by rashes and obvious itchiness, and can be actively given anti-allergy drug treatment, such as oral paracetamol, vitamin C and so on. If the itching is obvious, you can apply topical glycerine lotion topical application. After making appropriate symptomatic treatment, we should actively search for allergens that cause allergy, and if necessary, we can take the baby to the hospital for allergen testing, and according to the test results, we should pay attention to avoiding contact with the above allergens on weekdays. When the baby’s immune function is low, it is also easy to cause allergies, so pay attention to more physical exercise on weekdays to enhance physical fitness, if necessary, can be carried out immunoglobulin laboratory tests.
