Lumbar Spinal Stenosis: Symptoms, Causes, and Non-Surgical Options
Lumbar spinal stenosis is one of the more common reasons older adults in the Loop and surrounding downtown Chicago neighborhoods come into Loop Spine & Sports Center. It tends to develop gradually, which means many patients live with it for months or years before understanding what is actually going on.
This post covers what stenosis is, how it differs from other causes of low back pain, and what non-surgical care can realistically offer.
What Is Lumbar Spinal Stenosis?
Lumbar spinal stenosis refers to a narrowing of the spinal canal in the low back, the space through which the spinal cord and nerve roots pass. As that space narrows, it can put pressure on the nerves, leading to pain, numbness, or weakness. Stenosis is most often a wear-and-tear condition, developing over years as decreased spinal curves, thickened ligaments, bone spurs, and compressed disc space gradually reduce the available room in the canal.
It is worth distinguishing stenosis from a single traumatic injury. Most patients we see did not have one specific event that caused it. Instead, it is the cumulative result of age-related changes in the spine, and it tends to show up more often in patients over 50.
Common Causes
Age-related degeneration of the discs and joints in the low back
Thickening of ligaments inside the spinal canal
Bone spurs that form as the spine adapts to years of wear
Degenerated discs that lose height and allow the vertebrae to move closer together
In some cases, a naturally narrower spinal canal that becomes symptomatic with age
You can read more about how disc degeneration factors into this on our degenerated discs page, and how disc issues more broadly relate to low back pain on our low back pain page.
Symptoms to Watch For
Lumbar stenosis has a fairly recognizable pattern, though it does not look the same for everyone:
Low back pain that may radiate into the buttocks or legs
Numbness, tingling, or cramping in the legs, especially with walking or standing
Symptoms that improve when sitting or leaning forward, such as leaning on a shopping cart
Leg fatigue or weakness that limits how far you can comfortably walk
That last pattern, pain that eases with sitting or forward bending and worsens with standing or walking, is one of the more distinguishing features of stenosis and is a key part of what we evaluate for during an exam. It is also part of what separates stenosis from sciatica caused by a disc issue, which often behaves differently with position.
If your symptoms are more consistent with nerve pain radiating down one leg regardless of posture, our sciatica page may be a better starting point, and a herniated disc could also be a contributing factor worth ruling out.
How Stenosis Is Evaluated
A thorough evaluation includes a review of your history, a physical and orthopedic exam, and digital X-rays if needed to assess the degree of narrowing and any related degenerative changes. In some cases, particularly when symptoms are severe, progressing, or involve significant weakness, advanced imaging like an MRI through your primary care doctor or a specialist may be recommended before proceeding with care.
Being upfront about when a case needs that extra step is part of doing this evaluation honestly rather than treating every case the same way.
Non-Surgical Care Options
For many patients, stenosis can be addressed conservatively before surgery is ever discussed. Dr. Trottier's approach typically draws on a few tools depending on what the evaluation shows:
Flexion Distraction
Flexion distraction is a gentle, non-thrusting technique that can help open up space in the spinal canal and reduce pressure on the nerves. It is often well tolerated by stenosis patients, including those who are not candidates for more forceful adjusting techniques.
Spinal Decompression Therapy
Spinal decompression therapy is another option for appropriate candidates, using a controlled, gentle stretching force to help create space around compressed disc space and reduce nerve irritation. For a deeper look at how this compares to surgical options, see our post on spinal decompression vs. surgery.
Chiropractic Adjustments
Where appropriate, chiropractic adjustments can help address restricted spinal segments and misalignment contributing to symptoms elsewhere in the spine, working alongside the more targeted techniques above.
Being Honest About What This Can and Cannot Do
Non-surgical care can help many stenosis patients manage symptoms and stay active without surgery, but it does not reverse the underlying narrowing of the spinal canal. For patients with significant nerve involvement, progressive weakness, or symptoms that are not responding to conservative care, surgical consultation is a reasonable and sometimes necessary next step. Part of an honest evaluation is telling you where your case falls rather than promising an outcome that is not realistic for your situation.
