It is normal to have lymph nodes in the groin area, but it is not normal to have enlarged lymph nodes. Because the inguinal region is where the lymph nodes converge, there will be many lymph nodes that cannot be touched under normal circumstances, but when the body suffers from some heterogenous invasion, such as bacterial infection, viral infection, tuberculosis infection, and caused by allergic factors, they can cause swollen and painful lymph nodes. At this time, it can be treated by corresponding medication, and then adjust the diet structure, and at the same time, it can be combined with herbal treatment, which is more effective. A small number of swollen lymph nodes are caused by diseases of the blood system, such as lymphoma, and some are caused by lymph node metastasis of malignant tumors, so puncture biopsy of lymph nodes or excisional biopsy can be performed if necessary to clarify their nature. During the examination, alcohol should not be consumed.
