Spinal stenosis is a narrowing of the open spaces within your spine, which can put pressure on your spinal cord and the nerves that travel through the spine. Spinal stenosis occurs most often in the neck and lower back.
While some people have no signs or symptoms, spinal stenosis can cause pain, numbness, muscle weakness, and problems with bladder or bowel function.
Spinal stenosis is most commonly caused by wear-and-tear changes in the spine related to aging. In severe cases of spinal stenosis, doctors may recommend surgery to create additional space for the spinal cord or nerves.
Spinal stenosis occurs when the space within the spinal canal or around the nerve roots becomes narrowed. ...
Many people have evidence of spinal stenosis on X-rays, but have no signs or symptoms. When symptoms do occur, they often start gradually and worsen over time. Symptoms vary, depending on the location of the stenosis:
When to see a doctor
While some people are born with a small spinal canal, most spinal stenosis occurs when something happens to reduce the amount of space available within the spine. Causes of spinal stenosis may include:
Bone spurs on spine
As your spine ages, it's more likely to experience bone spurs or herniated disks. These problems can reduce the amount of space available for your spinal cord and the nerves that branch off it. ...
Most people with spinal stenosis have passed the age of 50. When younger people develop spinal stenosis, the cause is typically a genetic disease affecting bone and muscle development throughout the body.
Severe cases of spinal stenosis may cause:
Preparing for your appointment
If your family doctor suspects that you have spinal stenosis, he or she may refer you to a doctor who specializes in disorders of the nervous system (neurologist). Depending on the severity of your symptoms, you might also be referred to a spinal surgeon.

What to expect from your doctor
Tests and diagnosis
Spinal stenosis can be difficult to diagnose because its signs and symptoms resemble those of many age-related conditions. Imaging tests may be needed to help pinpoint the true cause of your signs and symptoms.
Treatments and drugs
The type of treatment you receive for spinal stenosis may vary, depending on the location of the stenosis and the severity of your signs and symptoms.
The goal is to relieve the pressure on your spinal cord or nerve roots. For example, a laminectomy removes the back part (lamina) of the affected vertebra to create more room within the spinal canal. In some cases, vertebrae also may need to be fused together to maintain the spine's strength.
In most cases, surgery helps reduce spinal stenosis symptoms. But some people's symptoms stay the same or get worse after surgery. Surgical risks include infection, a tear in the membrane that covers the spinal cord, a blood clot in a leg vein and neurological deterioration.
Laminectomy enlarges your spinal canal to relieve pressure on the spinal cord or nerves. This pressure can be caused by a variety of problems, including bony overgrowths within the spinal canal (...
