Chronic pharyngitis is caused by a variety of factors that lead to congestion and edema of the pharyngeal mucosa and submucosal tissues, as well as lymph follicle hyperplasia. Common causes include recurrent inflammation of the tonsils, long-term consumption of spicy foods, gastrointestinal dysfunction, acid reflux, and prolonged exposure to smoking and alcohol, which can lead to symptoms in the throat area. Patients may experience dry throat, sore throat, itchy throat, a foreign body sensation in the throat, a feeling of obstruction, burning sensation, and irritative coughing, which in severe cases can lead to blood in the sputum. During examination, severe congestion and edema of the pharyngeal mucosa can be observed, and lymph follicle hyperplasia can be found on the pharyngeal wall, pharyngeal lateral bands, and the base of the tongue. For treatment, patients can take Shuanghuanglian oral liquid, which has been shown to have good therapeutic effects. A light diet, abstaining from smoking and alcohol, and avoiding spicy and irritating foods can gradually improve the condition and prevent recurrent attacks. (The use of medications should be under the guidance of a doctor.)
