How to do sore throat after doing gastroscope

A few patients show transient sore throat or pharyngeal foreign body after examination, which is caused by damage to the laryngeal mucosa. No special treatment is required, and the symptoms will be relieved soon. Throat lozenges or mouthwash can also be used to relieve symptoms. Pharyngeal anesthesia is performed during gastroscopy.
