The swollen lymph nodes are not good for a month, and this situation should be dealt with in the following aspects: First, further examination is needed to clarify the primary lesion that caused the swollen lymph nodes. If the swollen lymph nodes persistently do not go away, it is considered that the primary lesion causing the swollen lymph nodes has not achieved effective treatment, which in turn leads to the persistence of the swollen lymph nodes. For example, common causes of swollen lymph nodes in the neck include gingivitis, and enlarged tonsils. Second, if the inflammation causes swollen lymph nodes, it is necessary to take antibiotics and other drugs. Thirdly, if the above methods cannot make the swollen lymph nodes disappear, surgical excision can be considered as an option. The swollen lymph nodes will be removed and sent for pathological examination for clarification.
