Recurrent sore throat can be caused by reflux pharyngitis, chronic pharyngitis, chronic tonsillitis and other reasons. 1. Reflux pharyngitis: stomach acid and other gastric substances repeatedly stimulate the throat area, often resulting in recurring pain in the throat area, and may also have a foreign body sensation and other symptoms. 2. Chronic pharyngitis: its main symptoms are sore throat, foreign body sensation and cough in the morning. In the acute attack period, the symptoms of recurrent pain in the throat will appear. 3. Chronic tonsillitis: when the body’s resistance is lowered, bacterial infection again causes inflammation of the tonsils and recurrent sore throat symptoms. It is recommended that when patients experience recurrent sore throat, they should consult a doctor in time to find out the cause and standardize the treatment under the doctor’s guidance.
