The old tradition says that fish is a hairy product, but this concept is actually an outdated one, because there is no such thing as a hairy product in Western medicine, so it is possible to eat during the period of wheals, and this does not have any effect. The reason is that it is a local inflammation caused by bacterial infection, and if the infection is weak, the disease can quickly return to normal. However, if the infected bacteria is more virulent, it will cause a very large scope of inflammation, and if there is no early intervention, the scope of infection will definitely expand further, involving the orbit, which will bring more impact, and may even lead to intracranial infection. Therefore, after the appearance of mydriasis, it is important to select sensitive antibiotic drugs early to control the local inflammation, reduce the symptoms and shorten the course of the disease.
