Spinal stenosis usually occurs as a person ages.
Spinal stenosis may also be caused by:
Spinal stenosis is narrowing of the spinal column that causes pressure on the spinal cord, or narrowing of the openings (called neural foramina) where spinal nerves leave the spinal column.
During a physical exam, your health care provider will try to find the location of the pain and learn how it affects your movement. You will be asked to:
Your provider will also move your legs in different positions, including bending and straightening your knees. This is to check your strength and ability to move.
To test nerve function, your provider will use a rubber hammer to check your reflexes. To test how well your nerves sense feeling, your provider will touch your legs in many places with a pin, cotton swab, or feather. To check your balance, your provider will ask you to close your eyes while keeping your feet together.
A brain and nervous system (neurologic) examination helps confirm leg weakness and loss of sensation in the legs. You may have the following tests:
Many people with spinal stenosis are able to be active with the condition, although they may need to make some changes in their activities or work.
Spine surgery will often partly or fully relieve symptoms in your legs or arms. It is hard to predict if you will improve and how much relief surgery will provide.
In rare cases, injuries caused by pressure on the nerves are permanent, even if the pressure is relieved.
Symptoms often get worse slowly over time. Most often, symptoms will be on one side of the body, but may involve both legs.
Symptoms are more likely to be present or get worse when you stand or walk. They often lessen or disappear when you sit down or lean forward. Most people with spinal stenosis cannot walk for a long period.
More serious symptoms include:
Your provider and other health professionals will help you manage your pain and keep you as active as possible.
Treatments for back pain caused by spinal stenosis include:
Spinal stenosis symptoms often become worse over time, but this may happen slowly. If the pain does not respond to these treatments, or you lose movement or feeling, you may need surgery.
During some spinal surgeries, the surgeon will remove some bone to create more room for your spinal nerves or spinal column. The surgeon will then fuse some of the spine bones to make your spine more stable. But this will make your back more stiff.
Call your provider if you have symptoms of spinal stenosis.
