Inflammation of tonsils is usually caused by infection or inflammatory involvement of surrounding organs. 1. Common pathogens of infection include beta-hemolytic streptococcus, staphylococcus, etc. When the patient’s body immunity decreases, it usually increases the risk of infection. 2. Acute pharyngitis, rhinitis and other peripheral tissues and organs when inflammation occurs, may involve the tonsils, resulting in inflammation of the tonsils. Common symptoms of tonsil inflammation in the acute stage include high fever, drowsiness, loss of appetite, etc. Chronic tonsillitis is mostly caused by recurrent episodes of acute tonsillitis, which can result in caseous secretions in the tonsil crypts, accompanied by symptoms such as bad breath, and the patient will suffer from a low-grade fever, malaise, and dizziness. Patients may experience low-grade fever, fatigue, dizziness, etc. If symptoms of throat discomfort occur, we should be vigilant about tonsillitis, and recommend that the diagnosis be confirmed after timely examination by a specialist.
