Spinal stenosis is a narrowing of the open spaces within your spine, which can place stress upon your spinal cord and the nerves that travel through the spine. Spinal stenosis takes place most frequently in the neck and lower back.
While some individuals have no signs or symptoms, spinal stenosis can result in pain, numbness, muscle weakness, and problems with bladder or intestinal function.
Spinal stenosis is most commonly caused by wear-and-tear changes in the spine associated with aging. In severe cases of spinal stenosis, doctors may suggest surgery to produce extra room for the spinal cord or nerves.
