Central stenosis – also known as central canal stenosis or
central spinal stenosis – is a narrowing of the central spinal
canal, which is the region of the spinal canal that directly
surrounds the spinal cord and cauda equina. Normally, the bones
of the spinal column, called vertebrae, form a long shield
around the spinal cord. This column of bones surrounds the
spinal cord, protecting spinal nerves from damage. The joints
and cartilage of the spinal column also allow the back and neck
to move, bend, and stretch. Occasionally, however, a condition
in the spinal column can cause pressure on the spinal cord,
resulting in symptoms like pain, numbness, tingling, and
weakness. Central stenosis occurs when a bulging disc, herniated
disc, bone spur, or other condition begins to take up space and
encroach on the middle part of the spinal column, effectively
causing a narrowing of the spinal canal. When central stenosis
occurs, the symptoms are often: - Dull aching pain concentrated
