The diagnosis of chronic tonsillitis mainly relies on the patient's usual symptoms, medical history, and physical examination by the doctor. The symptoms of chronic tonsillitis typically include sore throat, frequent colds, dry throat, itchy cough, foreign body sensation, and even snoring during sleep among some individuals. Medical history is particularly crucial. If there are recurrent acute episodes, characterized by sore throat, painful swallowing, and sometimes accompanied by high fever, and these episodes occur more than four times a year, this history is significant for diagnosing chronic tonsillitis. Additionally, physical examination by a doctor, who will inspect the tonsils, is essential for making the diagnosis of chronic tonsillitis. The main basis for diagnosis includes symptoms, medical history, and physical examination.
