If you have leg pain, you can consult orthopedics, neurology, vascular surgery, etc. according to other symptoms and medical history. 1. If leg pain is accompanied by lower limb weakness and lumbar pain radiating from the lumbar region to the lower limbs, it may be caused by lumbar disc herniation, spinal stenosis and other spinal disorders, in which case you can consult an orthopedic surgeon. 2. If leg pain is accompanied by numbness and abnormal sensation in the lower limbs, and there is no pain in the lower back, it may be caused by peripheral nerve and spinal cord lesions, and you can go to the Department of Neurology for consultation at this time. 3. If leg pain is accompanied by coldness and intermittent claudication, there may be problems with the blood vessels in the lower limbs, such as arterial occlusion, so you can go to the vascular surgery department. In addition to the above mentioned causes, if leg soreness occurs after strenuous exercise, it may be caused by the accumulation of lactic acid, which is a normal phenomenon and can be relieved naturally after rest. If the symptoms of leg soreness persist or other symptoms appear, it is recommended to consult a doctor to determine the cause of the problem and receive appropriate treatment.
