This condition is a narrowing of the spinal canal that results from the degeneration of bones, discs, or joints in the cervical spine. Spinal stenosis is typically caused by age and overuse, which can lead to degeneration of the spine’s discs, bones and joints. Vertebrae may slip out of their normal alignment and rub harmfully against each other. Damage from the rubbing causes the formation of bony growths called bone spurs. Bone spurs may push into the spinal canal or foramen space. Tissues around the spinal cord may thicken and push into the spinal canal, creating pressure against the spinal cord or nerve roots.
Symptoms depend on the area being pinched. Pressure on a nerve root can cause pain, weakness and numbness in the shoulders, arms and hands.
