Allergic rhinitis in children may cause coughing, which is mainly seen clinically as follows: 1. Upper airway cough syndrome, mainly due to partial backflow of nasal snot into the nasopharynx and then dripping into the throat, resulting in an irritating cough for the patient, which is obvious during the daytime and is reduced at night after lying down. Patients mostly have a foreign body sensation in the nasopharynx and a feeling of mucous phlegm adhering to the nasopharynx. Some patients may have dry throat, foreign body sensation in the throat, hoarse voice and other related manifestations over time. 2. Children with allergic rhinitis, the onset of which has not been systematically treated for more than 2 years, may clinically induce asthma, thus manifesting as recurrent coughing, accompanied by chest tightness, shortness of breath, shortness of breath and other related changes. In conclusion, allergic rhinitis in children may cause coughing, which most of the time indicates aggravation of the lesion and requires active clinical treatment.
