Pediatric urticaria has a low probability of healing on its own, and a greater probability of persisting or even leading to chronic urticaria. Urticaria is a common allergic disease, and the probability of self-healing varies depending on the course of the disease and the trigger. 1, acute, most of them are direct contact with allergens, most commonly such as steamed eggs, fish, shrimp, crab, seafood and other foods, without medication, the body metabolizes all the allergens out of the body, the symptoms can disappear, depending on the type, in about 3-7 days, rarely more than 10 days. Self-healing can be expected. However, expecting treatment, if the child has an allergic constitution, or cross-allergy, it may lead to prolongation of the disease and become chronic urticaria. 2. For chronic urticaria, most of them are caused by physical causes (allergic constitution), chronic infections (Helicobacter pylori infection in the stomach), and chronic diseases (thyroid disease). The rash manifestations can also heal on their own because the cause persists and the cause is very unlikely to heal on its own. 3. Infectious urticaria This type of urticaria is aggressive and may have symptoms such as laryngeal obstruction and abdominal pain. If not treated in time, it may lead to anaphylactic shock, which in turn may be life-threatening, and there are precedents (very few) of sudden death. Therefore, immediate treatment is recommended upon detection. In summary, it cannot be denied that urticaria has the possibility of self-healing, but the treatment itself has few side effects, and combined with the characteristics of the disease and the risks of not treating it, early treatment is recommended.
