There are many reasons for urticaria. The main reasons are infection and allergic reaction of the body to certain substances. A considerable part of urticaria occurs in the process of infectious diseases, such as upper respiratory tract infection, bronchitis, pneumonia, etc. In this case, urticaria mostly occurs in the acute stage of the disease. There are also some children who have urticaria because their bodies are allergic to something, which may be food, such as milk, fish, etc., or it may be caused by an insect bite, or they are allergic to certain pollen. There are also some children who have a family genetic history, which means that their parents or other elders in the family have allergies. Don't be nervous if you have urticaria, you can go to the hospital to see a doctor. Generally speaking, we should first make clear why urticaria occurs, that is, we should find out the causes of urticaria. Some situations need to be recalled by yourself. If we can find out the substances that cause allergies, we can avoid contact again. If it is urticaria caused by infectious diseases, antibiotics are the first choice. For local skin itching, try not to scratch it to avoid secondary infection. Some antihistamines can be used to relieve itching and ensure necessary rest. Of course, these drugs should be used under the guidance of a doctor.

After urticaria subsides, there is no trace on the skin, so it will not affect the beauty of the skin.
