Acute tonsillitis is a relatively common otolaryngological disease, primarily caused by acute bacterial infection leading to inflammation of the tonsils, resulting in throat pain, swollen tonsils, and in severe cases, it may affect breathing and swallowing. In terms of examination, it is firstly recommended to perform an indirect laryngoscopy to observe the extent of inflammation within the throat and to determine the presence of any throat obstruction. It is also necessary to conduct a routine blood test to help assess the severity and type of bacterial infection. Regarding treatment, oral medication is primarily considered, generally focusing on antibiotics, which can be complemented by nebulization and traditional Chinese medicine. If the inflammatory response is particularly severe and oral medication is ineffective, further infusion therapy may need to be considered, but it generally falls under common ailments. Typically, the recovery time is about a week, although there are individual differences. After treatment, regular follow-up checks are needed to observe the recovery process.
