Small anterior lymph nodes of the diaphragm are localized inflammation leading to enlarged lymph nodes, which can be treated with oral antibiotics, such as cefdinir, levofloxacin, etc. Metastatic tumors need comprehensive treatment such as surgery.
You should go to the hospital for further examination, because this disease may be an isolated attack or a symptom after metastasis of cancer cells, so you should firstly diagnose what causes the diaphragmatic lymph nodes.
If it is an isolated attack, local inflammation is considered, and anti-inflammatory drugs can be taken for treatment, such as cefdinir, levofloxacin, etc. However, if it is a lymph node formed by metastasis of cancer cells, surgery is needed to remove the cancer cells, but if the condition is already very serious, surgery will not be of much use, and radiotherapy or targeted therapy can be done in this case.
Small lymph nodes in front of the diaphragm should be consulted in hospital in time and standardized treatment.
