Specialized Care for Spinal Narrowing, Lower Back Pain, and Leg Symptoms
Pain, heaviness, numbness, or weakness in the legs that becomes worse with standing or walking may be associated with lumbar spinal stenosis, a condition in which spaces within the lower spine become narrowed and place pressure on or irritate the spinal nerves.
Lumbar spinal stenosis is commonly associated with degenerative changes of the spine and becomes more prevalent with age. Symptoms can range from mild lower back discomfort to significant leg symptoms that limit walking, standing, exercise, and everyday activities.
At TOPS Institute, we provide comprehensive evaluation and personalized treatment for lumbar spinal stenosis in Los Angeles and Beverly Hills. Our approach focuses on identifying the structures responsible for a patient’s symptoms and providing nonsurgical and minimally invasive treatment options when appropriate.

What Is Lumbar Spinal Stenosis?
Lumbar spinal stenosis is narrowing of one or more spaces within the lumbar spine that can reduce the room available for spinal nerves.
The lumbar spine contains the spinal canal as well as smaller openings through which individual spinal nerves travel. Degenerative changes can gradually narrow these spaces.
Lumbar stenosis may involve:
- Central canal stenosis: Narrowing of the main spinal canal
- Lateral recess stenosis: Narrowing along the pathways traveled by nerve roots before they exit the spine
- Foraminal stenosis: Narrowing of the openings where individual spinal nerves exit the spine
Not everyone with spinal narrowing visible on an MRI experiences symptoms. Treatment decisions should therefore consider the patient’s symptoms and physical findings in addition to imaging.
What Causes Lumbar Spinal Stenosis?
Lumbar spinal stenosis most commonly develops as a result of age-related and degenerative changes affecting the lower spine.
Potential causes and contributing factors include:
- Lumbar spondylosis and spinal arthritis
- Degenerative disc disease
- Loss of spinal disc height
- Bone spur formation
- Thickening of spinal ligaments
- Facet joint enlargement or arthritis
- Disc bulging or herniation
- Spondylolisthesis
- Previous spinal injury or surgery
- Naturally narrow spinal anatomy
Several of these changes can occur simultaneously, gradually reducing the space available for spinal nerves.

Symptoms of Lumbar Spinal Stenosis
The symptoms of lumbar spinal stenosis depend on the location and severity of the narrowing and which nerves are affected.
Patients may experience:
- Lower back pain
- Pain extending into the buttocks or legs
- Numbness or tingling in the legs or feet
- Leg weakness
- Heaviness or fatigue in the legs
- Cramping or aching with walking
- Difficulty standing for extended periods
- Reduced walking tolerance
- Symptoms that improve when sitting or leaning forward
Symptoms may affect one or both legs and can gradually become more noticeable over time.
Some patients have relatively little lower back pain but significant difficulty standing or walking because of their leg symptoms.
What Is Neurogenic Claudication?
Neurogenic claudication is a characteristic group of leg symptoms caused by compression or irritation of spinal nerves associated with lumbar spinal stenosis.
Patients may experience aching, heaviness, numbness, tingling, weakness, or discomfort in the buttocks and legs after standing or walking for a period of time.
Symptoms commonly improve when the patient:
- Sits down
- Bends or leans forward
- Changes position
- Rests after walking
Leaning forward can temporarily increase the available space within portions of the lumbar spine, which may explain why some patients feel more comfortable walking while leaning over a shopping cart or similar support.
This pattern can be an important clue when evaluating suspected lumbar spinal stenosis.
Lumbar Spinal Stenosis vs. Sciatica
Lumbar spinal stenosis and sciatica are related but are not the same condition.
Lumbar spinal stenosis describes narrowing within the lower spine.
Sciatica describes a pattern of nerve-related symptoms that may include pain, numbness, tingling, or weakness traveling from the lower back or buttock into the leg.
If spinal stenosis compresses or irritates a lumbar nerve root, it can cause lumbar radiculopathy, which may produce sciatica symptoms.
However, lumbar spinal stenosis can also affect multiple nerves and cause neurogenic claudication involving both legs.

How Is Lumbar Spinal Stenosis Diagnosed?
Diagnosing lumbar spinal stenosis involves determining whether spinal narrowing corresponds to the patient’s symptoms.
At TOPS Institute, evaluation may include a detailed review of:
- Where symptoms occur
- Whether symptoms affect one or both legs
- Walking and standing tolerance
- Positions that worsen or relieve symptoms
- Numbness or tingling
- Muscle weakness
- Reflexes and sensation
- Previous spinal conditions or procedures
- Treatments already attempted
A physical and neurological examination can provide additional information about strength, sensation, reflexes, mobility, and nerve function.
When clinically appropriate, an MRI may be used to evaluate the spinal canal, nerve roots, discs, facet joints, and surrounding soft tissues. X-rays or CT imaging may also be appropriate in certain circumstances.
Because spinal narrowing may appear on imaging without causing symptoms, imaging results should be considered alongside the patient’s clinical presentation.
How Is Lumbar Spinal Stenosis Treated?
Treatment depends on the severity of spinal narrowing, the patient’s symptoms and functional limitations, neurological findings, and response to previous care.
When appropriate, nonsurgical treatment may include:
- Physical therapy
- Activity modification
- Home exercise
- Appropriate medications
- Strengthening and mobility exercises
- Posture and movement modifications
The goal is often to reduce symptoms and maintain or improve the patient’s ability to stand, walk, exercise, and participate in everyday activities.
When nerve-related symptoms remain significant despite conservative care, interventional pain management may be considered.
Epidural Steroid Injections for Lumbar Spinal Stenosis
When lumbar spinal stenosis causes inflammation or irritation around spinal nerves, an epidural steroid injection may be considered for appropriately selected patients.
An epidural steroid injection delivers medication into the epidural space surrounding the spinal nerves with the goal of reducing inflammation and relieving nerve-related symptoms.
Depending on the patient’s anatomy, symptoms, and location of nerve involvement, treatment may include a:
Lumbar Epidural Steroid Injection
or
Lumbar Transforaminal Epidural Steroid Injection
A transforaminal approach delivers medication near a particular spinal nerve root and may be considered when symptoms correspond to a specific affected nerve.
The appropriate treatment approach is determined individually based on the patient’s diagnosis and clinical findings.
Does Lumbar Spinal Stenosis Require Surgery?
Not every patient with lumbar spinal stenosis requires surgery.
Patients with mild or moderate symptoms may be managed with conservative treatment or interventional pain management depending on their individual circumstances.
Surgical evaluation may be considered when spinal stenosis causes severe functional limitations, persistent symptoms despite nonsurgical treatment, or significant neurological deficits.
Treatment recommendations should consider not only the degree of narrowing visible on imaging but also the patient’s symptoms, neurological findings, overall health, and treatment goals.
When Should You Seek Medical Attention?
Patients should consider an evaluation when lower back or leg symptoms:
- Persist or progressively worsen
- Limit walking or standing
- Cause recurrent numbness or tingling
- Produce leg weakness or heaviness
- Interfere with work, exercise, or daily activities
- Do not improve with conservative treatment
Certain neurological symptoms require prompt medical evaluation. Seek urgent care for new or rapidly worsening weakness, loss of bowel or bladder control, numbness around the groin or saddle region, or other significant neurological changes.
Lumbar Spinal Stenosis Treatment at TOPS Institute
Lumbar spinal stenosis can affect much more than the lower back. For some patients, the greatest limitation is the inability to comfortably stand, walk, exercise, travel, or participate in everyday activities because of persistent leg symptoms.
At TOPS Institute, we focus on determining whether spinal narrowing seen on imaging corresponds to the patient’s symptoms and identifying the nerves and structures involved.
Treatment is individualized based on the patient’s diagnosis, neurological findings, functional limitations, and goals. When appropriate, targeted procedures such as lumbar epidural steroid injections or lumbar transforaminal epidural steroid injections may be incorporated into a comprehensive nonsurgical treatment plan.
For patients seeking lumbar spinal stenosis treatment in Los Angeles or Beverly Hills, TOPS Institute provides specialized interventional pain management focused on reducing symptoms, preserving mobility, and improving function.

Frequently Asked Questions About Lumbar Spinal Stenosis
What does lumbar spinal stenosis feel like?
Lumbar spinal stenosis may cause lower back pain along with aching, numbness, tingling, heaviness, cramping, or weakness in the buttocks and legs. Symptoms may become more noticeable while standing or walking and improve when sitting or leaning forward.
What is the main cause of lumbar spinal stenosis?
Degenerative changes of the spine are a common cause. Disc degeneration, facet joint arthritis, bone spurs, thickened ligaments, and loss of disc height can gradually reduce the space available for spinal nerves.
What is neurogenic claudication?
Neurogenic claudication refers to leg symptoms caused by spinal nerve compression associated with lumbar spinal stenosis. Symptoms commonly develop or worsen with standing and walking and may improve with sitting or bending forward.
Is lumbar spinal stenosis the same as sciatica?
No. Spinal stenosis describes narrowing within the spine. Sciatica describes nerve-related symptoms traveling into the leg. Lumbar spinal stenosis can cause sciatica when the narrowing irritates or compresses a nerve root.
Learn More About Lumbar Radiculopathy (Sciatica)
Can lumbar spinal stenosis cause pain in both legs?
Yes. Depending on where narrowing occurs and which nerves are affected, lumbar spinal stenosis may cause symptoms in one or both legs. Central spinal canal narrowing may affect multiple nerve roots.
Can epidural steroid injections help lumbar spinal stenosis?
Epidural steroid injections may be considered for selected patients when lumbar spinal stenosis causes nerve irritation and radicular symptoms. These injections are intended to reduce inflammation around affected spinal nerves. The degree and duration of symptom relief vary between patients.
Learn About Lumbar Epidural Steroid Injections
Can lumbar spinal stenosis be treated without surgery?
Yes. Many patients can initially be treated nonsurgically depending on the severity of their condition. Treatment may include physical therapy, activity modification, appropriate medications, and interventional procedures. Surgery may be considered when significant symptoms or neurological problems persist despite nonsurgical care.
Does spinal stenosis get worse over time?
Lumbar spinal stenosis is often associated with degenerative changes that can progress over time, but the course of symptoms varies considerably between individuals. Imaging findings and symptoms do not always progress at the same rate, which is why treatment should be based on the patient’s clinical condition rather than imaging alone.
