Chronic tonsillitis is a relatively common ENT (Ear, Nose, and Throat) disease with various clinical symptoms. Most patients may experience enlarged tonsils, a sensation of a foreign body in the tonsils, and recurrent sore throat, though the pain generally isn't very severe. Patients with chronic tonsillitis usually do not have a fever. However, if an acute episode of chronic tonsillitis occurs, it may cause fever, primarily due to acute bacterial infection leading to fever. In terms of treatment, blood tests and laryngoscopic examinations are necessary to observe the extent of the inflammation. Generally, antibiotic treatment to fight the infection is considered, with a treatment period of about one week. (Please use medication under the guidance of a doctor.)
