A more common clinical condition in children with sneezing and nosebleeds is allergic rhinitis, accompanied by nasal mucosal erosion and ruptured bleeding. The child often sneezes with an itchy nose and a runny nose because of the symptoms of allergic rhinitis. The nose is more itchy and the child will involuntarily touch, rub and pick the nose, which very easily leads to the erosion of the mucous membrane in the lee area at the front of the nasal septum, thus inducing arterial bleeding inside. Clinically, in this case, first of all, under the guidance of outpatient doctors, local drops of compound menthol nasal drops can be used to lubricate the mucous membrane of the nasal cavity. At present, the child’s nasal mucosa has bleeding and mucosal erosion, so the use of some nasal spray hormone drugs is suspended.
