Acute tonsillitis is mainly caused by an acute bacterial infection, with the most common symptoms being sudden throat pain, and significant redness and congestion of the tonsils, which may also include pus formation if severe. In terms of treatment, oral medication is primarily preferred, generally focusing on antibiotics, and may include nebulization as well as traditional Chinese oral medications. If inflammation is particularly severe and oral medications are ineffective, infusion therapy may be considered. Some patients may also experience fever, thus requiring physical cooling methods, and if the temperature exceeds 38.5 degrees Celsius, antipyretic medications should be considered, along with regular blood tests.
