Narrowing of the lumbar intervertebral space is the shortening of the space between two adjacent vertebrae. Narrowing of the lumbar intervertebral space is caused by prolonged exertion, excessive pulling and stimulation, and excessive weight bearing on the lumbar region leading to herniation or degeneration of the intervertebral discs, which ultimately causes narrowing of the intervertebral space. It manifests itself as pain and numbness in the lumbar region and lower limbs, muscle soreness, and limitation of activities. Clinically, narrowing of the lumbar intervertebral space can be detected on the basis of X-ray, CT and MRI examinations. Narrowing of the lumbar vertebral space generally does not require special treatment, daily to maintain good posture, do not stand for a long time, stooping, weight bearing or ambulation, it is recommended to sleep on a hard bed, daily to strengthen the lumbar back muscle exercise; pain is obvious through local massage and other physical therapy to improve blood circulation, or take blood circulation and pain relief, nutrient nerve medication. If the lumbar and lower extremity pain and numbness, activity is limited lumbar spinal narrowing symptoms, it is recommended to consult a doctor in a timely manner, with the help of the doctor to clarify the condition, and targeted treatment or therapy.
