If you have been dealing with back pain, leg pain, or that uncomfortable numbness that creeps in when you walk too far, spinal stenosis could be the reason. It is one of the most common spine conditions in adults over 50, yet many people go years without knowing what is actually causing their pain.
Many individuals with lumbar spinal stenosis experience difficulty walking long distances and often find relief by leaning forward, which helps to relieve pressure on their lower back.
Understanding what spinal stenosis is, how it develops, and what your treatment options look like can make a significant difference in the decisions you make about your care.
What Is Spinal Stenosis?
Spinal stenosis is the narrowing of the spinal canal which is the bony channel that houses your spinal cord and nerve roots. When that space shrinks, it puts pressure on the nerves running through it. That pressure is what creates the pain, numbness, tingling, and weakness that patients commonly describe. Spinal stenosis affects the legs by exerting pressure on the nerves that control leg movement and sensation, leading to pain, weakness, or numbness.
It can happen anywhere in the spine, but lumbar spinal stenosis (affecting the lower back) is the most frequent form. Cervical stenosis (affecting the neck) is the second most common and can cause more serious symptoms if left untreated. Spinal stenosis pain can vary in sensation, such as dull aches, electric-like, or burning sensations, and may be intermittent.
Common Spinal Stenosis Symptoms
Symptoms vary depending on where the narrowing occurs and how severe it is. Symptoms of spinal stenosis often develop gradually and worsen over time, sometimes improving when sitting or leaning forward. Common symptoms include pain, numbness, tingling, muscle weakness, and limited mobility. Many people notice their symptoms gradually worsen over time rather than appearing suddenly.
Lumbar Stenosis Symptoms
- Leg pain or cramping when walking or standing, which is one of the hallmark signs. Leg pain from spinal stenosis can manifest as a deep ache or burning sensation that travels down one or both legs, often worsening with activity and improving with rest. The pain usually eases when you sit down or lean forward.
- Low back pain that comes and goes
- Numbness or tingling in the legs, feet, or buttocks
- Weakness in one or both legs; leg weakness can lead to difficulty with walking, standing, or muscle signaling.
- A feeling of heaviness in the legs during activity
Common symptoms of spinal stenosis include lower back pain, leg symptoms such as pain and numbness, reduced mobility, weakness in the legs or feet, and in severe cases, bowel or bladder dysfunction. Symptoms of lumbar spinal stenosis may include back pain, burning pain radiating into the buttocks and legs, numbness, tingling, cramping, or weakness in the legs, and loss of sensation in the feet. Common symptoms of spinal stenosis also include a sense of fatigue, discomfort, or changes in sensation such as numbness or tingling, particularly in the buttocks, thighs, and legs, which may worsen with walking or standing and improve with sitting.
The pattern of pain that worsens with walking and improves with rest or forward bending has a specific name: neurogenic claudication. It happens because certain positions reduce the pressure on compressed nerves. Physical therapy for spinal stenosis may involve exercises to strengthen back and leg muscles, improve flexibility, and teach safe movement techniques, all aimed at improving leg function.
Cervical Stenosis Symptoms
- Neck pain and stiffness
- Numbness or weakness in the arms or hands
- Balance problems or difficulty with coordination
- In severe cases, difficulty walking or bladder/bowel changes
Cervical spinal stenosis symptoms should not be ignored. Pressure on the spinal cord in the neck can become serious. Individuals with spinal stenosis may experience symptoms that vary based on the location of the nerve compression, including pain, numbness, and weakness in the arms or legs, depending on whether the stenosis is cervical or lumbar. Seek an evaluation promptly if you notice neurological changes like hand weakness or coordination problems.
What Causes Spinal Stenosis?
Most cases develop gradually as the spine ages. The most common cause of lumbar spinal stenosis is osteoarthritis, which leads to gradual wear and tear on the spine, typically beginning around age 50. Acquired spinal stenosis, which develops later in life, is primarily caused by degenerative changes in the spine, such as herniated discs and degenerative disc disease. This is normal wear and tear but that does not mean you have to live with the pain. Certain bone diseases can also contribute to the development of spinal stenosis.
Age-Related Changes
The most common cause is the natural degeneration of spinal structures over time. As we age, the discs between vertebrae begin to dry out and shrink. Degeneration can also affect the lumbar vertebrae and the facet joints, which are critical for spinal stability and movement. Bone spurs can form. Ligaments thicken. All of these changes can gradually reduce the space available for nerves.
Other Contributing Factors
- Osteoarthritis: cartilage breakdown causes the joints of the spine to enlarge and thicken
- Herniated discs: disc material that pushes into the spinal canal can compress nearby nerves
- Thickened ligaments: he ligamentum flavum (a tough ligament inside the spinal canal) can stiffen and fold inward over time
- Spondylolisthesis: when one vertebra slips forward over another, it narrows the canal
- Congenital stenosis: some people are born with a naturally narrower spinal canal, making them more susceptible to symptoms earlier in life
Genetics, body weight, and physical activity history can all influence how quickly these changes develop and how symptomatic they become.
Diagnostic Imaging Tests for Spinal Stenosis
Accurate diagnosis of spinal stenosis relies heavily on advanced imaging tests that allow healthcare providers to see inside the spinal canal and pinpoint the source of your symptoms. Magnetic resonance imaging (MRI) is often the first choice, as it provides detailed images of the spinal cord, nerve roots, discs, and surrounding soft tissues. MRI can reveal exactly where the spinal canal is narrowed and how much pressure is being placed on the nerves.
Computed tomography (CT) scans are another valuable tool, offering high-resolution images of both bones and soft tissues. CT scans are especially helpful for visualizing the bony structures of the spine and identifying bone spurs or other abnormalities that may be contributing to spinal stenosis. X-rays, while less detailed, are commonly used to assess the alignment of the spine, detect narrowing of the disc spaces, and spot any changes in the vertebrae.
In some cases, a myelogram may be recommended. This test involves injecting a contrast dye into the spinal canal before taking X-rays or CT scans, which helps highlight areas where nerves are compressed. These imaging tests, used alone or in combination, are essential for confirming a diagnosis of spinal stenosis and guiding your treatment plan.
What Are Spinal Stenosis Treatments?
A diagnosis starts with a thorough physical examination and a review of your symptoms. A physical examination is crucial for assessing symptoms, mobility, and spinal health. Your physician will ask about when and where your pain occurs, what makes it better or worse, and whether you have noticed any weakness or balance changes. To diagnose spinal stenosis, healthcare providers use a combination of medical history, physical examination, and imaging tests.
Imaging plays a key role. Common diagnostic tools include:
- MRI: provides the most detailed view of soft tissues, discs, and nerve compression
- CT scan: useful for visualizing bone structure and spinal canal dimensions
- X-rays: helpful for assessing bone alignment, disc space narrowing, and the presence of bone spurs
Spinal stenosis is diagnosed by integrating findings from the physical examination and imaging. Lumbar spinal stenosis diagnosed through these methods can be differentiated from other conditions with similar symptoms.
At Valley Orthopaedic Specialists, our spine team evaluates each patient’s condition individually. The right imaging approach depends on your specific symptoms and medical history.
Spinal Stenosis Treatment Options
Treatment for spinal stenosis is not one-size-fits-all. Most patients start with non-surgical care. The primary goal of treatment is pain relief and to relieve pain associated with nerve compression. Nonsurgical treatment options are often effective for many patients. Surgery becomes an option when conservative treatments do not provide adequate relief, or when neurological symptoms are progressing.
Common non-surgical treatments for lumbar stenosis include physical therapy, medications, epidural steroid injections, lifestyle adjustments, and minimally invasive procedures.
Non-Surgical Lumbar Stenosis Treatment
Non-surgical treatment works well for a large number of patients, especially those with mild to moderate symptoms. Spinal injections are another nonsurgical treatment option that can help relieve back pain and spinal stenosis.
Physical Therapy
Physical therapists play a key role in guiding patients through exercises and activity modifications as part of spinal stenosis treatment. Physical therapy is often the first line of treatment. A therapist will work with you on exercises that strengthen the muscles supporting your spine and improve flexibility. Flexion-based movements (those that bring you into a forward bend) are particularly effective for lumbar stenosis because they open up space in the spinal canal. Physical therapy can also help relieve pressure on pinched nerve roots, which may alleviate associated pain and instability.
Medications
Anti-inflammatory medications (NSAIDs) can reduce swelling and manage pain. Muscle relaxants, nerve pain medications like gabapentin, and short-term oral steroids may also play a role depending on your specific symptoms.
Epidural Steroid Injections
Epidural steroid injections are administered between the spinal bones (vertebrae) and the surrounding spinal cord area, delivering anti-inflammatory medication directly to the area around the compressed nerve. These injections can be used to reduce inflammation and provide temporary relief from pain associated with spinal stenosis. They do not fix the underlying narrowing, but they can significantly reduce inflammation and pain, often providing enough relief to allow patients to engage more effectively in physical therapy.
Activity Modifications
Small changes in how you move and position yourself can make a real difference. Many patients find that activities like cycling (which keeps the spine in a flexed position) are more comfortable than walking. Using a shopping cart or walker can relieve symptoms during errands by encouraging a forward-leaning posture.
Surgical Spinal Stenosis Treatment
When non-surgical treatments are not enough, surgery may be the right next step. Surgical intervention is typically considered for severe spinal stenosis when conservative measures fail to relieve symptoms. A spinal surgeon is responsible for recommending and performing spinal surgery procedures to relieve nerve compression. The goal of spinal surgery is decompression, creating more room for the nerves by relieving pressure on the spinal cord or nerve roots and restoring mobility. If conservative treatments do not provide sufficient relief, surgery may be recommended, with approximately 80% to 90% of patients experiencing pain relief post-surgery.
Laminectomy (Decompression Surgery)
The most common surgical procedure for spinal stenosis is laminectomy, which is typically performed in the lumbar region to relieve pressure on the spinal nerves. The surgeon removes part of the lamina (the back arch of the vertebra) along with any thickened ligament or bone spurs pressing on the nerves. This procedure not only relieves pain but also improves leg function and mobility. It is highly effective for lumbar stenosis and has a strong track record of relieving leg pain and neurogenic claudication.
Minimally Invasive Spine Surgery
Minimally invasive techniques allow surgeons to perform decompression through smaller incisions, with less disruption to surrounding muscles and tissue. Minimally invasive procedures are a modern, effective approach for treating lumbar spinal stenosis, often resulting in faster recovery and better outcomes compared to traditional surgery. The result is typically less post-operative pain, a shorter hospital stay, and a faster return to daily activities. To learn more about this approach, read our detailed overview of minimally invasive spine surgery at VOS.
Spinal Fusion
In cases where spinal instability is present alongside stenosis, such as with spondylolisthesis, spinal fusion surgery may be performed in addition to decompression. This procedure connects two or more vertebrae together to stabilize that segment of the spine. Spinal fusion surgery has been shown to relieve chronic neck pain and improve quality of life in patients with traumatic injuries or accidents.
At VOS, our fellowship-trained spine surgeons use the technique best suited to each patient’s anatomy and goals. Dr. Anthony Viola, D.O. specializes in minimally invasive and robotic spine surgery, with fellowship training from the University of Connecticut in the latest spinal surgical techniques.
How Posture and Daily Habits Affect Spinal Stenosis
The way you carry yourself matters. Poor posture places extra load on the spinal structures most affected by stenosis and can worsen pain symptoms associated with spinal stenosis. Strengthening your core, avoiding prolonged standing, and maintaining a healthy body weight can all slow the progression of symptoms and support the results of treatment.
For a deeper look at the relationship between spinal health and posture, see our post on the importance of posture and orthopaedic health.
Preventing Spinal Stenosis
Although some people are born with a naturally narrow spinal canal, many cases of spinal stenosis are linked to lifestyle and age-related changes. Taking steps to keep your spine healthy can help reduce your risk. Regular exercise, especially activities that strengthen your core and back muscles, helps support the spine and alleviate pressure on the discs and joints. Practicing good posture, both when sitting and standing, can also minimize strain on the spinal structures.
Maintaining a healthy weight reduces stress on the lumbar spine and lowers the risk of developing musculoskeletal and skin diseases that can contribute to spinal problems. Avoiding smoking and eating a balanced diet rich in nutrients that support bone health are also important preventive measures. Finally, taking frequent breaks to stretch and move throughout the day can help keep your spine flexible and reduce the risk of developing spinal stenosis or related skin diseases.
Managing and Living with Spinal Stenosis
Living with spinal stenosis means finding the right balance of treatments and lifestyle changes to manage symptoms and maintain your quality of life. Many people benefit from nonsurgical treatments such as physical therapy, which focuses on exercises to strengthen the muscles supporting the spine and improve flexibility. Nonsteroidal anti inflammatory drugs (NSAIDs) and steroid injections can help alleviate pain and relieve pressure on the nerves, making daily activities more comfortable.
For some, minimally invasive surgery may be necessary to address severe nerve compression and restore function. Working closely with an orthopedic surgeon or physical therapist ensures that your treatment plan is tailored to your specific needs and goals. Simple lifestyle modifications like maintaining a healthy weight, staying active, and avoiding heavy lifting can also make a big difference in managing symptoms. With the right support and a proactive approach, it is possible to alleviate pain, manage symptoms, and enjoy a fulfilling, active life despite spinal stenosis.
When Should You See a Spine Specialist?
Do not wait until the pain becomes unbearable. Seek an evaluation if:
- Your back or leg pain has persisted for more than a few weeks and is not improving
- You notice numbness, tingling, or weakness in your legs or arms
- You have started limiting your activities because of pain
- Walking has become difficult or uncomfortable
- You experience balance problems or coordination changes
If non-surgical treatments do not relieve your pain and neurological symptoms, spinal stenosis surgery may be considered for severe cases.
The earlier spinal stenosis is evaluated, the more treatment options are available. Structural changes in the spine do not reverse on their own, but the right care plan can significantly reduce your symptoms and help you get back to the activities you enjoy.
