Children are susceptible to swollen lymph nodes when pathogenic infections such as viral, mycoplasma or bacterial infections are present. When lymph node enlargement is induced, the child may experience pain in the lymph node area, which requires anti-inflammatory and symptomatic treatment. For viral infections, antiviral drugs such as antiviral oral solution or ribavirin granules can be given. If it is a bacterial infection, the application of cephalosporin or penicillin antibiotics can be given for treatment, the oral cefixime or amoxicillin granules. In case of mycoplasma infection, macrolide antibiotics such as azithromycin or erythromycin can be given. In case of severe symptoms, intravenous infusion of appropriate medication can be given. Lymphadenitis pain can be treated with Chinese herbal compresses applied to the lymph nodes, which can also significantly relieve lymph node pain and lymphadenitis symptoms.
