Chronic pharyngitis is caused by a variety of reasons; it results in congestion and edema of the pharyngeal mucosa and submucosal tissues, along with proliferation of lymphatic follicles. Patients may experience dryness, itching, foreign body sensation, obstruction, burning sensation, and irritative cough in the throat. Severe cases may lead to bloody sputum. Common causes can include repeated acute inflammatory stimuli such as tonsillitis, acute pharyngitis, or long-term smoking, alcohol consumption, spicy food intake, digestive system disorders, and gastroesophageal reflux, all of which can cause congestion and edema of the pharyngeal mucosa and submucosal tissues, as well as lymphatic follicle proliferation. Examination with a laryngoscope can reveal significant congestion in the pharyngeal mucosa, uvula, and uvula, and lymphatic follicles can be found on the posterior pharyngeal wall, at the base of the tongue, and in the pharyngeal recesses. Treatment initially requires identifying and avoiding the cause. Nebulization inhalation can be used to alleviate local congestion and swelling, and adopting a light diet and quitting smoking and drinking can gradually lead to improvement and prevent recurrence.
