If the swelling of inner thigh lymph nodes is caused by local inflammation, it can be eliminated in 5-7 days after eliminating the primary lesion, or in 2-3 weeks in severe cases. For lymph node enlargement caused by tumor, it needs to depend on the treatment. If the lymph nodes are swollen on the inner thigh due to inflammation of the lymph nodes, or if there is a bacterial infection in the lower limbs, antimicrobial treatment can be carried out according to laboratory tests. If the lymph node enlargement is mild, it usually takes 5-7 days for the enlarged lymph nodes to be eliminated after the local infection is completely controlled. In patients with severe lymph node enlargement, it usually takes 2~3 weeks to eliminate. If a malignant tumor causes enlarged medial thigh lymph nodes, such as colon malignancy, lymphoma or metastatic tumors, it may invade the surrounding organs, resulting in enlarged medial thigh lymph nodes. This condition requires removal of the primary tumor or diseased lymph nodes, supplemented by radiotherapy and chemotherapy treatment. Therefore, how long does it take to get rid of swollen lymph nodes in the inner thigh cannot be generalized, and it needs to be decided according to the cause of the disease and the severity of the disease. It is recommended that patients go to the hospital in time to clarify the cause of the disease and follow the doctor’s instructions for treatment.
