Stenosis in the spine is a narrowing of the canal that is around the spinal cord and nerve roots in your back. It can happen as part of aging. Sometimes bone and other tissue grow into this canal and press on the nerves that branch out from the spinal cord. This can cause pain, numbness, and weakness. When it happens in the lower part of your back, it is called lumbar spinal stenosis. It can cause problems in the legs, feet, and rear end (buttocks).
You may be able to get relief from the symptoms of spinal stenosis by taking medicine. Your doctor may suggest physical therapy and exercises to keep your spine strong and flexible. Some people try steroid shots to reduce swelling. If pain and numbness in your legs are still so bad that you cannot do your normal activities, you may need surgery.
Narrowing of the spinal canal can squeeze and irritate the nerve roots that branch out from the spinal cord. This is what causes pain and other symptoms. It usually starts gradually and gets worse over time. Symptoms may stay the same, get better, or get worse. Most often, it doesn't cause disabilities.
The most common symptom of lumbar spinal stenosis is leg pain that happens when you walk or stand but feels better when you sit. You feel pain in your legs because the nerve roots that pass through the lower spine extend to the legs. Symptoms occur when these nerve roots get squeezed.
Other symptoms may include:
Many people, especially those older than age 50, have some narrowing of the spinal canal but don't have symptoms. If there are symptoms, they may be very bad at times and not so bad at other times.
Treatments for lumbar spinal stenosis include:
Exercise and changing the way you do your activities may also help you feel better.
The doctor can usually diagnose lumbar spinal stenosis by:
Your doctor may try nonsurgical treatment, such as pain-relieving medicines, exercise, and physical therapy, for a period of time before ordering imaging tests. If treatment works, you may not need tests.
You can take steps to treat lumbar spinal stenosis symptoms at home. Be sure to talk with your doctor before you start home treatment.
Steps you can try include:
When nerve roots in the lower back (lumbar region) are squeezed, the pressure can affect nerves that extend into the legs. This can cause pain, numbness, and weakness in the legs and feet.
The risk of having lumbar spinal stenosis increases if you:
The most common cause of lumbar spinal stenosis is changes in the spine that can happen as you get older.
These changes include thickening of soft tissues, development of bony spurs, and the slow breakdown of spinal discs and joints over time. Any of these can narrow the spinal canal.
These age-related changes often happen when you have certain disorders. For example:
Other causes include:
Lumbar spinal stenosis is a narrowing of the spinal canal in the lower back, known as the lumbar area.
The spine is made up of bones called vertebrae. The spinal cord runs through an opening in the bones called the spinal canal. Sometimes bones and tissue grow into this canal and press on the spinal cord and/or the nerves that branch out from it. This causes pain, numbness, or weakness in the back, buttocks, legs, and feet.
Physical therapy for spinal stenosis may include stretching, strengthening exercise, and therapies like heat, ice, and massage. You'll learn different ways to do your activities so they don't cause pain. Your doctor or physical therapist will design a program. It will be based on your activity level, your physical fitness, and your pain level.
