Spinal Stenosis
of the back. These soft tissues support the back and help hold the different parts together.
Spinal stenosis is a narrowing of the spinal canal or of the spaces between the vertebrae where spinal nerves pass through. This narrowing is usually caused by arthritis or injury, and can cause symptoms for different reasons. пїЅ пїЅ
This article will only discuss spinal stenosis in the lower back. This is called "lumbar spinal stenosis. " пїЅ Other parts of the back can have spinal stenosis, too. пїЅ пїЅ
What are the symptoms of a spinal stenosis in the lower back? " пїЅ Spinal stenosis does not always cause symptoms. When it does, the most common symptoms are pain and tingling or numbness that spreads down the legs. These symptoms usually affect both legs, but the symptoms can be worse in one leg than the other. пїЅ пїЅ
Symptoms of spinal stenosis are usually worse when the person is walking or standing upright. Usually, the symptoms get better if the person sits down or bends forward at the waist, for example, while leaning over a shopping cart. пїЅ пїЅ
Is there a test for spinal stenosis? " пїЅ Yes. Tests, such as an MRI or a CT scan, can show what's going on inside the back. These tests can show if a person has bone spurs or other changes that happen with spinal stenosis. пїЅ пїЅ
In some cases, doctors also order tests called "electromyography " пїЅ or "nerve conduction studies. " пїЅ These tests measure how well electrical signals travel across the nerves that start in the spine. They can also show how well electrical signals travel from the spine to muscles. пїЅ пїЅ
Should I see a doctor or nurse? " пїЅ See your doctor or nurse right away if you have: пїЅ пїЅ
How is spinal stenosis treated? " пїЅ A small number of people end up needing surgery to treat a spinal stenosis. But most people do well with simpler treatments, such as: пїЅ пїЅ
How do I know if surgery is right for me? " пїЅ Your doctor will tell you if surgery is likely to help you. The 2 of you can decide together if surgery is right for you. The surgery can help with symptoms, but it is not usually necessary. People can often find ways to cope with their symptoms that do not involve surgery. пїЅ пїЅ
Surgery to treat a spinal stenosis involves exposing the spine and cutting away pieces of bone that are pinching the spinal cord or other nerves. In some cases, surgeons treating people with spinal stenosis will also decide to join together 2 vertebrae. This is called spinal fusion. Fusion is usually appropriate only for people who have spinal stenosis plus another condition called "spondylolisthesis, " пїЅ which is when 2 vertebrae no longer line up with each other. Spinal fusion can involve much more risk and a longer recovery time than regular surgery. пїЅ пїЅ
Is there anything I can do on my own to feel better? " пїЅ Yes. One of the most important things you can do to feel better is to stay as active as possible. Even if you have some pain or discomfort, you should not stay in bed or rest too long. пїЅ пїЅ
People used to think that bedrest was the best treatment for a bad back. The truth is, bedrest can actually make back problems worse. That's because the back can get weak and stiff with too much rest. пїЅ пїЅ
Find physical activities you like to do. If you have not been active for a while, start by doing just a few minutes of activity a few times a week. Then slowly do more. Also, ask your doctor if there are any activities, such as bending or lifting, that you shouldn't do. пїЅ пїЅ

Anatomy of the back
Low back pain can be caused by problems with the muscles, ligaments, discs, bones (vertebrae), or nerves. Often back pain is caused by strains or sprains involving the muscles or ligaments. These problems cannot always be seen on imaging tests, such as MRIs or CAT scans.
