For patients with lymphadenitis, it is generally considered that the reactive proliferation of lymph nodes is caused by inflammation or viral infection of nearby organs or soft tissues. In this case, it is suggested that patients should actively consider taking some anti-inflammatory drugs and antiviral drugs for active treatment. Patients with anti-inflammatory drugs can choose cephalosporins as their first choice, such as ceftazidime and cefixime. They can also actively choose some antiviral Chinese medicines, such as Banlangen granules and antiviral oral liquid, And Pudilan anti-inflammatory tablet and other drugs for active anti-inflammatory and antiviral treatment. During the treatment period, patients should pay attention to light diet, rest more, not stay up late, not tired, and drink more water and urinate more. After about ten days of active treatment, the swollen lymph nodes will gradually become smaller, and the pain and tenderness of lymph nodes will gradually improve or recover. Patients also need to focus on primary diseases, such as oral infection or gingivitis, and also need to take active etiological treatment for primary causes.
