Chronic pharyngitis is caused by a variety of reasons, leading to congestion, edema, and lymph follicle proliferation in the mucous membrane and submucosal tissue of the throat. Common causes include repeated inflammatory stimulation, intake of spicy foods, and local symptoms caused by gastric acid reflux. Patients may experience dryness, pain, itching, foreign body sensation, obstruction feeling, burning sensation, irritating dry cough, and hoarseness in the throat. In severe cases, there may even be blood in the sputum. During examination, swelling of the uvula and significant proliferation of lymph follicles can be found in areas such as the lateral pharyngeal wall, posterior pharyngeal wall, and the base of the tongue. In terms of treatment, patients need to first identify the cause, adopt a light diet, quit smoking and alcohol, exercise, avoid colds, and maintain a regular diet with post-meal physical activity for gradual improvement and to prevent recurrence.
