Lumbar disc herniation with radiating pain in the left lower extremity can be treated in several ways, including massage, physical therapy, traction therapy and surgery. 1. Orthopedic massage: it can relieve muscle spasm, improve local circulation and promote functional recovery. 2. Physical therapy: there are many specific classifications, which can be reasonably selected according to the condition and equipment conditions, such as electric excitement, infrared, ultrasonic, ultrasound, ionic introduction and other methods. 3. Traction therapy: it can reduce the pressure in the vertebral disk, reduce the friction between small joints, and relieve muscle spasm. 4. Surgery: If there is radioactive pain, numbness or difficulty in walking in the lower limbs, the symptoms are particularly severe, indicating that the nerve root compression is serious, and fusion of intervertebral discs or removal of intervertebral discs should be taken to decompress the lumbar vertebrae. Finally, it is recommended to go to the regular hospital, complete the examination, clear diagnosis, and follow the doctor’s instructions for treatment.
