Generally speaking, the swelling of lymph nodes is caused by inflammation of lymph nodes, that is, the inflammatory disease caused by bacterial infection of lymph nodes. Regular oral antibiotic treatment, such as first-generation cephalosporin or second-generation cephalosporin, cefradin, cefixime, cefaclor, etc. are all available. You can also take oral antibiotics of quinolones, such as levofloxacin, ciprofloxacin and so on. Generally anti-infection treatment will eliminate the lymph nodes in about 10-14 days, the volume of lymph nodes will be reduced, the pain will be relieved and the redness and swelling will subside. It is also possible that the swollen lymph nodes are caused by tumor metastasis, so fine needle aspiration can be performed, or the lymph nodes can be removed and sent to pathological examination. If it is confirmed that the swollen lymph nodes are caused by tumor metastasis, radical tumor surgery may be required and the lymph nodes in the area should be cleaned up accordingly.
