Why does spinal stenosis hurt more when walking?

The AAOS says standing up straight or walking usually makes the pain worse, and that leaning forward can increase the space available for the nerves. People often feel better sitting or leaning forward, and some find they can ride a stationary bike or walk while leaning on a shopping cart.

Can exercise help spinal stenosis?

The AAOS lists physical therapy, including stretching and core strengthening, among the treatments that often help manage symptoms, although it does not reverse the narrowing.

When is surgery considered for spinal stenosis?

The AAOS says surgery is generally reserved for people with poor quality of life because of pain and weakness, including difficulty walking for long. Healthy people who have decompression alone may return to normal activities after a few weeks.

Who treats spinal stenosis?

The AAOS lists physical therapy among the treatments that often help manage symptoms, and says chiropractic manipulation is generally safe and can help with some of the pain, but advises care if you also have osteoporosis or a herniated disc. You can find physical therapists and chiropractors near you in the SpinalCare directory.

Spinal stenosis is a narrowing of the space inside the spine that holds the spinal cord and nerves, usually from age-related wear and tear. In the lower back it may cause pain, numbness or weakness in the legs; the AAOS says standing or walking usually makes the pain worse and people often feel better sitting or leaning forward.

Overview

As the spine ages, discs lose height, the small joints develop arthritis and bone spurs, and ligaments thicken. Together these can crowd the space for the nerves. The AAOS names arthritis as the most common cause.

It is most common in adults over 60 and affects men and women equally. By age 50, up to 95% of people have some wear-and-tear changes in their spine (AAOS OrthoInfo).

Stenosis most often develops in the lower back and the neck (NIH NIAMS). This page focuses on the lower back, where the AAOS describes it as a common cause of low back and leg pain. For most people symptoms develop and progress slowly over time, and some people may not have any symptoms (NIAMS).

Common symptoms

Burning or aching pain in the buttocks or legs (sciatica), sometimes down to the foot
Numbness or tingling in the buttocks or legs
Weakness in the legs, or "foot drop", where the foot slaps the ground when walking
Back pain, depending on how much arthritis has developed
Symptoms that get worse with standing or walking and ease when sitting or leaning forward

Common causes

Arthritis and age-related wear and tear, the most common cause
Discs drying out and losing height
Bone spurs and thickened ligaments crowding the spinal canal
Being born with a narrower spinal canal, which tends to cause symptoms earlier, between ages 30 and 50
An injury to the spine (NIAMS)

Warning signs to act on

The sources list these as warning signs. Each one says what the source advises: some are emergencies (in the US, call 911 or go to the emergency room), others mean contacting a clinician promptly.

Numbness in your private (genital) area, loss of bowel or bladder control, or losing strength in your legs and being unable to walk: the AAOS describes this as acute cauda equina syndrome, a medical emergency

What usually helps

Physical therapy

Stretching, massage and core strengthening often help manage symptoms, according to the AAOS. Nonsurgical treatments don't improve the narrowing itself, though many people report they help relieve symptoms.

Anti-inflammatory medicines

NSAIDs can ease pain, but the AAOS notes they must be used carefully because they can cause stomach and kidney problems.

Steroid injections

Injections around the nerves can reduce swelling, pain and numbness, though not weakness. The AAOS advises no more than three a year.

Chiropractic care, with a caution

The AAOS says chiropractic manipulation is generally safe and can help with some stenosis pain, but care is needed if you also have osteoporosis or a herniated disc.

Surgery

Usually reserved for people whose quality of life is poor because of pain and weakness, including difficulty walking for extended periods. The main options are laminectomy and spinal fusion (AAOS).
