Swollen lymph nodes are symptoms, and there are various causes of swollen lymph nodes that cannot be immediately treated with medication. It is necessary to figure out what causes swollen lymph nodes. If it is simple acute lymphadenitis, submandibular lymphadenitis, caused by inflammation of the throat, it is indeed a bacterial infection, you can take antimicrobials, such as cephalosporins, penicillins to treat. If the lymph node enlargement is not caused by typical acute infection, it is tuberculosis causing tuberculous lymphadenitis, which is ineffective with antimicrobials and has to be treated with anti-tuberculosis. Anti-tuberculosis treatment is very long, using four or three combinations. Lymph node enlargement is not pure infection, may be malignant tumor metastasis or other parts of the blood disease, lymphoma, so the use of drugs is very complicated. Lymph node enlargement must not blindly take drugs, go to the hospital by the doctor to identify the cause of lymph node enlargement. When you see enlarged lymph nodes in the clinic, you should check whether it is simple infected lymphadenitis, necrotizing lymphadenitis, tuberculous lymphadenitis, lymphoma or metastatic disease. Progressive enlargement with fever is a candidate for needle biopsy of lymph nodes, or cutting off the whole lymph node after injection of anesthesia for frozen biopsy, to see what causes lymph node enlargement. Because the symptoms of enlarged lymph nodes are very complicated, it is necessary to find out the cause and then use drugs, not immediately use antibiotics for enlarged lymph nodes, if it is indeed an acute bacterial infection caused by simple lymph node enlargement, can be treated with antibiotics, and if it is not effective, come to the hospital immediately to do further examination.
