However, aging and age-related changes in the spine, injury, other diseases, or inherited conditions can cause narrowing of the spaces. Normally, the vertebral canal provides enough room for the spinal cord and cauda equina. Several factors can contribute to the narrowing of the spinal canal, leading to spinal stenosis. People with more severe stenosis may have problems with: The flexed position “opens up” the spinal column, enlarging the spaces between vertebrae at the back of the spine. Sitting or flexing the lower back or neck may relieve symptoms. Walking, standing, or extending the lumbar area of the spine can cause symptoms to worsen. Numbness or tingling that radiates down the arms into the hands.Symptoms of spinal stenosis in the neck may include: These may become more pronounced during standing or walking. Numbness, tingling, or cramping in the legs and feet.Burning pain or ache that radiates down the buttocks and into the legs, that typically worsens with standing or walking and gets better with leaning forward (flexion).Symptoms of spinal stenosis in the lower back can include: The symptoms you experience depend on the location of the narrowing in your spine. For most people, symptoms develop and progress slowly over a period of time, and some people may not have any symptoms. The narrowing creates pressure on the spine and related structures, causing symptoms. Symptoms of spinal stenosis may develop when the spaces within the spine narrow, most often in the lower back and neck. Spinal stenosis most commonly develops in the lumbar spine and cervical spine. There are many different structures in the anatomy of the back that work together to support your body.
