Pharyngitis refers to the inflammation of the mucous membrane of the pharynx. There are many clinical causes of pharyngitis, such as allergic pharyngitis, reflux pharyngitis, and infectious pharyngitis. Regardless of the type, pharyngitis can lead to clinical symptoms such as coughing and throat clearing actions, especially intense dry coughs in allergic pharyngitis, which tend to last a long time. For infectious pharyngitis, the coughing duration is short and the coughs are less intense. Therefore, it is certain that pharyngitis can cause coughing. Clinically, different types of medication are used to treat coughs caused by different types of pharyngitis. For coughs caused by allergies, anti-allergy treatments are required, and for coughs caused by reflux pharyngitis, medications that suppress stomach acid are needed.
