Spinal Stenosis is the narrowing of the spinal canal and nerve root canal can cause back and leg pain, especially when walking. Patients with foraminal spinal stenosis may require a doctor to perform a foraminotomy to enlarge the opening and reduce pressure on the nerve root.

Symptoms of lumbar spondylosis include pain, numbness and tingling radiating from affected areas and decreased flexibility of the spine. In advanced cases of lumbar spondylosis, spinal cord impingement caused by narrowing of the spinal canal may produce neurological problems, such as unsteady gait and an inability to control bladder functioning.
