Cough is one of the most common complaints and symptoms in respiratory patients. Chronic cough has a more complex etiology, so it is also often one of the most problematic chronic conditions for respiratory physicians. As a rhinologist, I often encounter coughing nasal patients in my outpatient clinics and find that patients with nasal disease often have a persistent cough, which often improves unexpectedly when the nose problem is under control. One of my patients, Jia Jia, is 9 years old, but has a history of coughing for 3 or 4 years. After examination, Jia Jia has typical allergic rhinitis, usually with blocked nose, itching, sneezing and itchy eyes. After avoiding exposure to allergens, specific immunotherapy, infection control, glucocorticoid control of inflammation, comprehensive use of decongestants, anti-allergy, anti-white triplet and mucolytic agents, the symptoms of cough and runny nose that have plagued Jiajia and her whole family for nearly 4 years are gradually disappearing, and Jiajia has changed from a child who has been dealing with hospitals for 3 or 4 years and is depressed every day to a sunny girl. In fact, many ear and nose diseases can cause coughing, such as: allergic rhinitis, adenoid hypertrophy, tonsillitis, pharyngitis, otitis media and even some oral diseases may be related to chronic coughing, which now has a unified medical name called upper airway cough syndrome. It feels like something is flowing or dripping from the posterior nostril into the larynx, and the cough is obvious, but the internist often does not hear the abnormality. The otorhinolaryngologist talks about coughing and just a little bit about the problems associated with us in chronic coughing. The human body as an organic whole, with the precise cooperation of various systems and organs is inseparable, and on the occasion of the Love Nose Day, we sincerely wish that our friends who are troubled by nose problems in the world will find health soon.
