What department to visit for foot is a comprehensive consideration based on the cause and symptoms of the patient: 1. If the painful swelling of the foot is caused by a history of contusion or trauma, you can generally register for orthopedic consultation. In the case of more detailed hospital subspecialties, such as orthopedic specialty hospitals, you can go to the hand and foot surgery department. 2. If the foot is red, swollen, hot and painful caused by gout, most patients are likely to have a history of gout and have elevated uric acid values, and should go to the endocrinology department. 3. If the patient’s toenails are grayish white, there is a possibility that they are gray nails, and they need to go to the dermatology department. If the skin of the foot has rashes, spots and other skin changes, it is also necessary to go to the dermatology department. 4. If there is pain and stiffness of the toes, deformation and deformity of the joints, it may also be rheumatoid arthritis, and it is necessary to go to the rheumatology department for consultation.
