The cervical spine refers to the portion of the spine in the neck. Cervical stenosis refers to narrowing of the spinal canal that protects the spinal cord and its branching nerves in the neck. The condition causes neck pain radiating to arms and hands and numbness or weakness in the legs.
Lumbar stenosis is the compression of spinal nerves in the lower back due to narrowing of spinal canal. It is one of the common causes of low back pain.
