Swollen lymph nodes in the neck with fever may be caused by acute cervical lymphadenitis, and patients are advised to take oral antibiotics for anti-inflammatory treatment, such as amoxicillin capsules and cephalosporins. If the oral effect is not obvious, it is recommended to change to subcutaneous or intravenous injection for anti-infection treatment, together with the use of analgesic and antipyretic drugs. In addition, for localized swollen areas, patients can apply hot compresses or herbal creams for localized treatment, which can usually provide significant relief after a few days. If the patient repeatedly has swollen lymph nodes, it is recommended to consult a doctor promptly and improve the corresponding examination to investigate the cause, and if necessary, to treat it by surgery.
