It is not straightforward to say exactly what department to see for the leg. It is based on the clinical symptoms that are currently manifested in the leg that determines exactly what department should be seen. For example, if there is pain in the joints, numbness and soreness in the legs, then you should go to the orthopedic department, which may be caused by arthritis or herniated disc. If there is a skin rash, or if there are pathological changes on the surface of the skin, then you should go to the hospital to see a dermatologist. If there is severe swelling or chills on the legs, and the pain is obviously vascular lesions, such as varicose veins, or vasculitis, then you should see a vascular surgeon. Of course, there are also some rheumatologic diseases, such as gouty arthritis and rheumatoid arthritis, which present pain in the joints of the legs. Therefore, you should first think about the general clinical symptoms yourself before you can judge the specific department.
