Narrowing. Stenosis is a condition where the tube inside the spine, the canal, is narrowed and potentially pinching on the spinal cord and/or spinal nerves. It can cause pain, weakness or numbness. It can be a problem from birth (congenital) or due to aging, injury or disease.
Cervical Stenosis. Normal aging of the spine with loss of spinal disc height and thickening of the ligaments that line the spinal canal contribute to the development of spinal stenosis. This gradual narrowing of the spinal canal can result in painless numbness and weakness in the hands and stiffness/spasticity of the lower extremities.
