Walking is not good for lumbar disc herniation because the cause of lumbar disc herniation is mainly the rupture of the annulus fibrosus under the action of external forces and the protrusion of the nucleus pulposus to compress the nerve, thus producing lumbago and sciatica. When the human body is upright when walking, the weight of the upper body is pressed on the disc through the vertebral body, which increases the pressure in the disc and increases the nucleus pulposus protrusion or disc bulge, which increases the compression and stimulation of the nerve roots, and the patient’s protrusion will increase, and symptoms such as pain and numbness will also increase. In the acute phase of lumbar disc herniation, especially within three months after the injury can not walk, to absolute bed rest, this period of rest is the best treatment, walking will only aggravate the disease.
