If there are symptoms of swollen abdominal lymph nodes and abdominal pain, the most common factor is infection, which may be both bacterial and viral, and in a few cases, due to tuberculosis infection. In this case, further tests such as blood tests, C-reactive protein, abdominal CT or abdominal MRI, and sometimes tuberculin test and calcitoninogen are needed. Depending on the results, medication, sometimes combined with Chinese herbal medicine, may be given with better results. During the treatment period, you should not drink drinks containing alcohol, do not eat spicy food, and increase rest appropriately. However, a few patients are caused by diseases of the blood system, such as lymphoma, and some are caused by lymph node metastasis of malignant tumors, such as stomach cancer, colon cancer, or even liver malignant tumors, etc. These require further improvement of other examinations for clarification.
