When tonsillitis occurs, the main symptom is pain in the throat, especially when swallowing, which is mainly due to inflammatory infection, so the use of antiviral drugs or antimicrobials to control the infection is the main pain relief method for the cause. Penicillins or cephalosporins are preferred, and different administration methods need to be chosen according to the severity of the disease. Systemic application of glucocorticoids, where appropriate, is beneficial to control the infection and reduce swelling, and can also quickly eliminate the sensation of pain. For patients who have no obvious effect after 2-3 days of drug treatment, it is necessary to improve the pharyngeal examination as soon as possible to exclude the possibility of peri-tonsillar abscess. If an abscess is formed, the pus should be excised and drained as soon as possible so that the symptoms can be effectively relieved. At the same time, bacterial culture and drug sensitivity tests should be done on the pus to select the most sensitive drugs to further control the infection and prevent serious complications.
