Lumbar disc herniation refers to degenerative changes in the lumbar intervertebral disc, which may result in partial or complete rupture of the fibrous ring and protrusion outward alone or together with the nucleus pulposus and cartilage end plate, which may stimulate or compress the sinus nerve and nerve root causing pain and numbness in the legs. It can be treated by bed rest, physiotherapy, medication, or surgery: 1. bed rest: two weeks of strict bed rest is required, with lumbar circumference to gradually move down to the ground, avoiding frequent bending or lumbar weight-bearing activities on a daily basis to relieve leg numbness caused by lumbar disc herniation; 2. physiotherapy: infrared light, hot compresses, microwaves and other physiotherapy modalities can be performed to relax the local tense muscles and Increase local blood circulation to relieve lumbar muscle tension and neuropathic leg numbness caused by lumbar disc herniation; or traction on the pelvis to relax the muscles, restore the original height of the vertebral space, relieve the pressure in the spinal canal, and improve the symptoms of neuropathic leg numbness caused by nerve compression; 3, medication: aspirin, ibuprofen and other non-steroidal anti-inflammatory drugs can be used under the guidance of a doctor, and vitamin B12 can be used as an adjunct. 4.Surgical treatment: It is suitable for patients with severe and recurrent symptoms of numbness of lumbar pain and numbness and obvious nerve involvement, who can undergo traditional open surgery, such as total laminectomy, laminectomy, hemilartebral laminectomy, and minimally invasive discectomy. It can relieve the nerve root or spinal cord compression by the herniated disc and relieve the leg numbness caused by the nerve compression by the herniated disc. In addition, patients with lumbar disc herniation should also pay attention to increasing the functional exercise of the lumbar back, such as five-point support, small swallow fly and other exercises.
