Spinal Stenosis

If standing or walking brings on aching, heaviness, or numbness in your legs — and sitting or leaning forward makes it stop — you may have lumbar spinal stenosis, a narrowing of the spinal canal that compresses the nerves of the lower back. It is one of the most common reasons adults over 50 seek a pain specialist, and one of the most overtreated: many patients are told surgery is inevitable when a structured, non-surgical plan has never been tried. At Modal Pain Management, at 369 Lexington Avenue, Floor 25, in Midtown Manhattan steps from Grand Central Terminal, Dr. Alex Movshis, MD — dual board-certified in anesthesiology and pain medicine, with fellowship training at the Icahn School of Medicine at Mount Sinai — evaluates spinal stenosis with a root-cause approach: confirm which structures are compressing which nerves, then treat the inflammation and pain generators with image-guided, non-opioid procedures rather than masking symptoms with opioids. Same-week appointments are available.

What Is Spinal Stenosis?

Spinal stenosis means a narrowing of the spaces inside the spine — the central canal that houses the spinal cord and cauda equina, or the lateral recesses and neural foramina where individual nerve roots exit. When these spaces narrow, the nerves within them are compressed, producing pain, numbness, tingling, and weakness in the territory those nerves supply. The condition is most often degenerative, developing gradually from the accumulated wear of decades; less commonly it is congenital (a naturally narrow canal that becomes symptomatic with only mild degenerative change) or secondary to spondylolisthesis, trauma, or prior surgery. Authoritative overviews of the condition are published by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) and the National Institute of Neurological Disorders and Stroke (NINDS).

Two points matter for treatment planning. First, the location of the narrowing determines the symptom pattern — lumbar stenosis affects the legs, cervical stenosis affects the arms and, in severe cases, the spinal cord itself. Second, the severity on imaging does not reliably predict the severity of symptoms. Some patients with dramatic narrowing on MRI have modest complaints; others with moderate stenosis can barely walk a block. This is why treatment should target your functional limitation and pain, not the picture on the scan — a principle that guides every plan Dr. Movshis builds.

Lumbar vs. Cervical Spinal Stenosis

The two common forms of spinal stenosis behave differently, carry different risks, and call for different levels of urgency.

Lumbar stenosis is by far the more common presentation in our Midtown Manhattan practice. Patients typically describe a shrinking “walking budget”: they can walk to the corner, then must stop; next month it is half a block. Many notice that pushing a shopping cart or leaning on a walker lets them go farther — the flexed posture mechanically opens the canal. Cervical stenosis more often presents as neck pain with radiating arm symptoms. When the spinal cord itself is compressed (myelopathy), early recognition matters because cord damage can become irreversible; we coordinate prompt neurosurgical referral in those cases and do not attempt to manage progressive myelopathy with injections.

Causes and Risk Factors

Degenerative lumbar spinal stenosis is rarely caused by a single structure. The canal narrows from several directions at once:

• Ligamentum flavum thickening. The ligament along the back wall of the canal hypertrophies and buckles inward with age — often the single largest contributor to central stenosis.
• Facet joint arthropathy. Arthritic enlargement of the facet joints narrows the lateral recess and foramen from behind. The same facet joints are frequently an independent pain generator, which is why stenosis and facet-mediated back pain so often coexist.
• Disc bulging. Degenerated discs lose height and bulge circumferentially, narrowing the canal from the front.
• Osteophytes (bone spurs). Arthritic bone overgrowth further encroaches on the canal and foramina.
• Degenerative spondylolisthesis. Slippage of one vertebra on another (most often L4 on L5) compounds the narrowing.

Risk factors include age over 50, a congenitally narrow canal, female sex (degenerative spondylolisthesis is more common in women), prior lumbar surgery, and conditions such as Paget’s disease or achondroplasia that alter bone architecture. A congenitally narrow canal explains why some patients develop stenosis symptoms in their 40s with only modest degenerative change — there was little room to spare to begin with.

Symptoms: Understanding Neurogenic Claudication

The signature of lumbar spinal stenosis is neurogenic claudication — poorly localized pain, heaviness, cramping, numbness, or weakness in the buttocks, thighs, and legs that is provoked by standing upright and walking and relieved within minutes by sitting or bending forward. It differs from vascular claudication (poor circulation) in several clinically useful ways: vascular pain is typically a tight calf cramp at a reproducible walking distance that stops promptly with standing still, while neurogenic claudication often requires sitting or flexion for relief and may be accompanied by tingling or back pain. The Cleveland Clinic’s overview of spinal stenosis summarizes this symptom pattern well for patients.

Other common features include:

• Low back pain that coexists with the leg symptoms
• Symptoms that are positional — better flexed, worse extended (lying on your stomach or arching backward narrows the canal further)
• Numbness or “dead” feeling in the feet or legs after walking
• Subjective leg weakness or unsteadiness after prolonged standing
• Night symptoms or restless legs–type discomfort in some patients

When leg pain follows a single sharp nerve-root distribution — for example, from the buttock down the back of one leg to the foot — that pattern overlaps with sciatica, and a disc herniation or foraminal stenosis at one level may be the driver rather than multi-level central stenosis. Distinguishing these patterns on examination changes the injection strategy.

Seek emergency care, not an office visit, if you develop new loss of bladder or bowel control, numbness in the groin or “saddle” area, or rapidly progressive weakness in both legs. These suggest cauda equina compression, which is a surgical emergency.

Diagnosis and Assessment

Diagnosis begins with the story — the positional pattern described above is often so characteristic that the examination largely confirms it. Dr. Movshis performs a focused neurological and musculoskeletal examination: gait observation (including whether symptoms can be provoked by treadmill-free walking in the office or by lumbar extension), strength, reflexes, and sensation testing in the legs, and provocative maneuvers to sort out how much of the pain is radicular (nerve-root) versus facet-mediated versus myofascial. A vascular screen — palpating foot pulses and reviewing risk factors — helps exclude peripheral arterial disease when the claudication story is ambiguous.

MRI of the lumbar spine without contrast is the standard confirmatory study: it shows the degree and levels of canal narrowing, ligamentum flavum thickness, disc contribution, and foraminal compromise. CT is reserved for patients who cannot have MRI or when fine bony detail matters; flexion–extension X-rays assess stability when spondylolisthesis is suspected. Electrodiagnostic testing (EMG/nerve conduction studies) is occasionally useful to distinguish stenosis from peripheral neuropathy when the examination is equivocal. If you already have imaging, bring it — a prior MRI is frequently sufficient, and we review the actual images with you, not just the report.

One diagnostic tool unique to interventional practice: when it is unclear whether the leg symptoms or the back pain is the dominant problem, a diagnostic injection can settle it. A fluoroscopically guided medial branch block that temporarily eliminates the back pain confirms a facet contribution, just as a selective nerve root block can confirm which foramen is symptomatic. This diagnostic precision is what turns “stenosis, treat it generically” into a targeted plan.

Treatment Options for Spinal Stenosis

There is no single “stenosis procedure” — there is a sequence, matched to your anatomy, your symptom pattern, and your response at each step. Our approach is layered, non-opioid, and evidence-based.

1. Conservative foundation

Structured physical therapy emphasizing flexion-biased exercises, hip and core strengthening, and activity modification is the evidence-supported starting point. Weight management reduces the mechanical load on the canal. NSAIDs can help symptomatically for appropriate patients. We are candid about the limits here: exercise cannot physically reopen a narrowed canal, but it improves walking tolerance, posture, and pain processing — and it preserves whatever gains procedures provide.

2. Epidural steroid injections (ESI)

Epidural steroid injections are the most established interventional treatment for symptomatic lumbar stenosis. Under fluoroscopic guidance, corticosteroid is delivered into the epidural space to reduce inflammation around the compressed nerve roots. For central stenosis with bilateral or multi-level symptoms, an interlaminar approach gives broad coverage; for single-level foraminal stenosis with one-sided radicular pain, a transforaminal approach targets the exiting root directly; a caudal approach suits certain lower-canal patterns. We set expectations honestly: the landmark LESS trial published in the New England Journal of Medicine (Friedly et al., 2014) found that in stenosis patients, adding steroid to epidural lidocaine offered little average advantage at six weeks — which is exactly why we treat ESI as one tool in a plan, select candidates carefully, reassess response after each injection, and never promise a cure. Many appropriately selected patients nonetheless obtain meaningful weeks-to-months of relief that restores walking capacity and enables rehabilitation; the procedure is repeatable within prudent annual limits.

3. Targeted nerve blocks

When a specific nerve root is the pain generator — common in foraminal stenosis — a selective nerve root block delivers anesthetic (with or without steroid) precisely to that root, serving both diagnostic and therapeutic purposes.

4. Treating the facet contribution

Because arthritic facet enlargement both narrows the canal and generates pain independently, many stenosis patients benefit from addressing the facets. A positive dual medial branch block identifies candidates for radiofrequency ablation of the medial branch nerves, which can provide months of back-pain relief and reduce the overall symptom burden even though it does not change the canal diameter.

5. Referral-level options: MILD and surgery

Two options sit outside our office-based scope, and we discuss them candidly. The MILD procedure (percutaneous image-guided lumbar decompression) removes small portions of thickened ligamentum flavum through a port about the diameter of a pencil, under imaging guidance, without general anesthesia. It is designed specifically for ligamentum-flavum–dominant lumbar stenosis with neurogenic claudication, and the published evidence base continues to develop (see the indexed literature on PubMed). Modal Pain Management does not currently perform the MILD procedure in-house; when a patient’s anatomy and insurance profile make it a reasonable consideration, we refer to qualified interventional colleagues in Manhattan and coordinate care before and after. Similarly, when stenosis produces progressive neurological deficit, myelopathy, or refractory symptoms after a genuine trial of conservative and interventional care, decompressive surgery (laminectomy/laminotomy, with fusion in selected cases) is the appropriate path, and we make that referral without delay and without framing it as a failure.

What to Expect During Your Visit

Your first appointment is a consultation, not a procedure mill. Dr. Movshis reviews your history and prior imaging (bring a printed copy of your MRI report, or email your imaging to info@modalpain.com ahead of your visit), performs the examination described above, and explains — in plain language, with your images on screen — which structures are narrowing your canal and which are generating your pain. You will leave with a written plan: what we recommend first, why, what the alternatives are, and what response would trigger the next step.

If an epidural injection or nerve block is part of the plan, it is performed in our office procedure suite under fluoroscopic guidance. The skin is numbed with local anesthetic; most patients feel pressure rather than pain. The injection itself takes roughly 15–20 minutes, followed by a short monitored recovery period. You should arrange a ride home. Most patients return to light activity the next day, avoiding strenuous exertion for 24–48 hours. We typically schedule a follow-up at two to four weeks to grade the response and decide whether a second injection, a different target, or a different strategy is indicated.

Cost and Insurance for Spinal Stenosis Treatment

Modal Pain Management is an out-of-network, commercial PPO practice. We accept most major commercial PPO plans and verify your benefits before your first visit at no cost or obligation, so you know your expected out-of-pocket responsibility — deductible, coinsurance, and copay — before any procedure is scheduled. With commercial PPO coverage, interventional spine procedures such as epidural steroid injections are typically covered benefits when medically indicated, with patient responsibility commonly ranging from a specialist copay to several hundred dollars depending on where you are in your deductible.

We do not accept Medicare, Medicaid, HMO plans, or workers’ compensation. If you carry one of these, we will tell you directly rather than book you into a visit you cannot use. Transparent self-pay pricing is available for patients without usable coverage, and insurance verification takes one business day in most cases. We do not bill surprise facility fees: procedures are performed in our office suite, not a hospital outpatient department, which is also why our episode-of-care costs are generally far below hospital-based interventional care.

Recovery and Long-Term Management

Lumbar spinal stenosis is a chronic structural condition, and honest long-term management means planning for that. After an injection, relief from the anesthetic is immediate but temporary; the steroid’s anti-inflammatory effect builds over 2–7 days, with peak benefit typically within two to three weeks. Duration of meaningful relief varies widely — weeks to many months — and tends to be shorter in stenosis than in acute disc herniation, because the mechanical narrowing remains. That is the rationale for pairing any procedure with sustained physical therapy, weight management, and activity strategy: the injection creates a window of reduced inflammation and pain; rehabilitation converts that window into durable walking capacity.

Many patients do well on a maintenance rhythm — periodic reassessment, a repeat epidural injection when symptoms rebuild (within safe annual limits), and continuous home exercise. Some patients stabilize for a year or more at a time. A smaller group progresses despite appropriate care, and for them we facilitate surgical consultation rather than escalating injections indefinitely. Our commitment is to the trajectory of your function — how far you can walk, how well you sleep, whether you can travel and work — not to any single procedure.
