Patients can follow the doctor’s instructions to use antibiotic drugs for treatment. Such as amoxicillin, cefadroxil, etc.. If the drug has no obvious effect, you can choose surgical treatment under the guidance of the doctor to remove the lesions of the mucosa and tissues to achieve therapeutic effects. 2. Chronic pharyngitis: these patients due to mucosal congestion and edema, which will lead to increased sputum secretion, especially in the early morning when waking up, phlegm is relatively more.
