Urticaria is a very common allergic disease in dermatology, mainly manifested by the appearance of wind clusters on the mucous membrane of the skin, which rise and fall and fade without leaving traces. This is because during the onset of urticaria, the skin mucosa and respiratory tract mucosa will have an edema-like reaction. In these cases, the trachea will also be swollen, so there will be symptoms of breathlessness and chest tightness, which are manifestations of acute urticaria. It is important to provide prompt symptomatic treatment in the presence of the above-mentioned conditions, and if necessary, emergency medical treatment.
