The inguinal lymph nodes require the following departments, such as general surgery, infection, and hematology. If an infection occurs in the lower extremity, the infection may spread to the groin, which will lead to lymphadenitis, and the lymph nodes will be swollen and painful, requiring anti-inflammatory treatment, such as intravenous antibiotics. In case of hematologic disorders, such as lymphoma, the inguinal lymph nodes may become enlarged and require hematology and bone marrow transplantation. If inguinal lymph node tuberculosis occurs, the lymph nodes will be enlarged, and the patient will need to be registered with the infection department, which will require regular anti-tuberculosis treatment. After arriving at the specialist, the patient needs to complete relevant tests, such as routine blood tests and ultrasound, which can clarify the diagnosis in combination with the patient’s symptoms and physical examination, and then decide how to treat the patient.
