When patients have symptoms of leg pain, it may be caused by physiological factors, and may also be caused by lumbar disc herniation femoral head necrosis and other diseases, the cause of different treatments, commonly used treatments for general treatment, physical therapy, drug therapy, surgical treatment and so on. 1. Physiological factors: patients may have excessive accumulation of lactic acid in the legs due to too long or strenuous exercise, thus causing leg pain. It is suggested that patients reduce the time or intensity of exercise and pay more attention to rest. Physiotherapy methods such as hot compresses and massages can also be used to promote local blood circulation and relieve leg pain. 2. Lumbar disc herniation: rupture of the lumbar disc leads to herniation of the nucleus pulposus, and the nerve root is stimulated, thus causing leg pain. Through lumbar massage, infrared and other physical therapy methods, patients can promote blood circulation in the lumbar region and reduce the stimulation to the nerve root, thus relieving the symptoms of leg pain. If the effect of conservative treatment is unsatisfactory, it is necessary to carry out surgical treatments, such as spinal endoscopic nucleus pulposus removal of intervertebral discs, and so on. 3. Necrosis of the femoral head: When patients suffer from necrosis of the femoral head, inflammatory exudation occurs in the hip joint, and the ligaments around the joint and the joint capsule become edematous, which stimulates the leg muscles of the hip joint and causes leg pain. Patients are advised to use non-steroidal anti-inflammatory and analgesic drugs, such as aspirin, to relieve pain. If the symptoms are severe, surgical treatment, such as hip replacement, may be required. When patients have symptoms of leg pain, it may also be caused by trauma, bone tumors and other factors, it is recommended that patients seek medical attention in a timely manner, to clarify the cause of the disease, and comply with the doctor’s instructions for standardized treatment.
