This article on anti-inflammatory injections refers to antibiotic injections. Lymph node enlargement can be treated with anti-inflammatory injections if it is caused by inflammation, but anti-inflammatory injections are generally not recommended if it is caused by fungus, viruses, connective tissue disease or tumors. Patients with enlarged lymph nodes can have anti-inflammatory injections if the lymph node inflammation is caused by bacterial infection, which can play an antibacterial and anti-inflammatory role. Commonly used anti-inflammatory injections include penicillin for injection, ceftriaxone sodium, levofloxacin and so on. Patients with enlarged lymph nodes who have fungal, viral, connective tissue disease or tumor-induced lymph node enlargement, anti-inflammatory injections are ineffective, so anti-inflammatory injections are not recommended in this case. Patients with enlarged lymph nodes are advised to consult a doctor to diagnose the cause of the problem and follow the doctor’s instructions according to the cause of the problem. Drugs should be applied under the guidance of a doctor.
