Overview

Lumbar spinal stenosis is a narrowing of the spinal canal in the lower back, usually from age-related changes in the bones and joints. The narrowed space can put pressure on the nerve roots, producing leg symptoms rather than back pain alone.

The classic pattern is neurogenic claudication: leg pain, heaviness or weakness with walking or standing that eases when you sit down or lean forward. This is why people with stenosis often find shopping carts or leaning over a counter surprisingly comfortable.

Typical Pattern

Leg pain, cramping, heaviness or numbness with walking
Symptoms eased by sitting, squatting or leaning forward
Often both legs affected
Back pain that may be present but is not the main complaint
Variable walking distance — sometimes better on a bike or uphill

Why It Develops

Stenosis develops gradually as discs, joints and ligaments change with age and the spinal canal narrows. It is more common in people over 60 and does not mean the spine is unsafe — most people manage well with conservative care.

Treatment

Education and structured exercise are first-line treatment
Manual therapy, walking programs and posture strategies can help
Pain relief is used short-term and appropriately
Surgery is considered for selected cases with severe, progressive symptoms that limit daily life despite conservative care

When to Get Assessed

Arrange assessment when leg symptoms limit walking or daily life, or when they are progressing. Seek urgent care for saddle numbness, difficulty urinating, loss of bladder or bowel control, or weakness developing in both legs.
