Chronic pharyngitis may cause otitis media, rhinitis and other diseases. 1. Otitis media: There is a tube between the pharynx and the ear called the Eustachian tube, which connects the pharynx and the ear. If chronic pharyngitis is severe, it will lead to congestion and edema of the mucous membrane around the pharyngeal opening of the Eustachian tube, blocking the Eustachian tube and forming secretory otitis media. 2. Rhinitis: chronic pharyngitis is a chronic inflammation of the mucous membrane and lymphatic tissues in the pharynx and throat, which can be complicated by rhinitis, with the manifestations of nasal congestion, runny nose, headache and dizziness. 3. Chronic pharyngitis is often recurrent and can cause throat discomfort. Patients with chronic pharyngitis should go to regular hospitals in time and standardize their treatment under the guidance of doctors to avoid delays.
