11 May Spinal Stenosis Symptoms, Causes, and Non-Surgical Treatment Options in North Texas
Spinal stenosis is one of the most common causes of back and leg pain in adults over 50, yet it remains widely misunderstood. Many patients spend months or even years managing symptoms with rest, over-the-counter medications, and activity avoidance before learning what is actually happening in their spine and what can realistically be done about it.
If you have been told you have spinal stenosis, or if you are experiencing symptoms that your doctor suspects may be related to stenosis, this guide is designed to give you a clear picture of what the condition is, why it causes the symptoms it does, and what the full range of treatment options looks like for patients in Carrollton, Denton, and the surrounding North Texas area.
What Is Spinal Stenosis?
The word stenosis comes from the Greek word for narrowing. Spinal stenosis refers to the narrowing of the spaces within the spine through which the spinal cord and nerve roots travel. When these spaces become too narrow, the neural structures inside can be compressed, generating pain, numbness, weakness, and other neurological symptoms.
Stenosis can occur in the central spinal canal, the lateral recesses, or the foramina (the openings through which individual nerve roots exit the spine). It can affect one or multiple levels of the spine simultaneously.
Where Does Spinal Stenosis Occur?
Lumbar spinal stenosis (lower back) is the most common form. It affects the nerve roots that supply the legs, buttocks, and lower body, producing a characteristic symptom pattern of leg heaviness, cramping, or pain that worsens with walking and standing and improves with sitting or leaning forward.
Cervical spinal stenosis (neck) involves narrowing of the spinal canal in the neck region. Because the spinal cord itself passes through this region, cervical stenosis can be more serious, potentially causing symptoms in both the upper and lower body, including difficulty with fine motor tasks and balance.
Thoracic spinal stenosis (mid-back) is the least common form because the thoracic spine is relatively immobile and protected from the mechanical stresses that accelerate degeneration elsewhere.
What Causes Spinal Stenosis?
Age-Related Degeneration
The most common cause of spinal stenosis is the natural degenerative process that affects the spine over time. As intervertebral discs lose height and hydration, as facet joints develop arthritic changes, and as the ligaments that support the spine thicken and stiffen, the cumulative effect is a gradual reduction in the space available for the spinal cord and nerve roots.
Bone Spurs
As the facet joints degenerate, the body often responds by forming extra bone called osteophytes. These bone spurs can protrude into the spinal canal or foramina, directly compressing neural structures.
Thickened Ligaments
The ligamentum flavum runs the length of the spine along the back of the spinal canal. With age and degenerative stress, these ligaments can thicken and buckle inward, reducing the space available in the spinal canal. Ligament thickening is one of the most significant contributors to lumbar spinal stenosis.
Spondylolisthesis
Spondylolisthesis is a condition in which one vertebra slips forward relative to the one below it. This slippage can significantly reduce the available space in the spinal canal and foramina and is a common cause of significant lumbar stenosis, particularly in older adults.
Symptoms of Spinal Stenosis
Lumbar Stenosis Symptoms
Neurogenic claudication is the hallmark symptom of lumbar spinal stenosis. It is characterized by pain, heaviness, cramping, or weakness in the legs that comes on with walking or prolonged standing and is relieved by sitting down or bending forward. This positional pattern occurs because bending forward slightly opens the spinal canal and reduces pressure on the compressed nerve roots.
Other symptoms include aching or burning pain in the lower back that radiates into the buttocks and legs, numbness or tingling in the legs or feet, weakness in one or both legs, reduced walking tolerance, and balance problems in more advanced cases.
Cervical Stenosis Symptoms
Cervical stenosis symptoms include neck pain that may radiate into the shoulders and arms, numbness or weakness in the arms or hands, difficulty with grip strength or fine motor tasks, and in cases of spinal cord compression: balance problems, coordination issues, or bowel and bladder dysfunction.
Non-Surgical Treatment Options for Spinal Stenosis
Physical Therapy
Physical therapy designed specifically for spinal stenosis focuses on strengthening the core muscles that support the spine, improving flexibility, and practicing flexion-based exercises and postures that open the spinal canal and reduce nerve compression. An experienced physical therapist familiar with stenosis can significantly improve a patient’s walking tolerance and daily function.
Epidural Steroid Injections
Epidural steroid injections are one of the most effective interventional treatments for lumbar spinal stenosis, particularly for patients whose primary symptom is leg pain associated with nerve root inflammation. By delivering corticosteroid medication directly into the epidural space adjacent to the compressed nerve roots, these injections reduce inflammation and can provide meaningful relief lasting weeks to several months.
Selective Nerve Root Blocks
When stenosis is causing compression at a specific nerve root level, a selective nerve root block can both confirm the diagnosis and provide targeted therapeutic relief. This procedure delivers medication precisely to the affected nerve root and is particularly useful when the pattern of symptoms corresponds to a specific spinal level.
Spinal Cord Stimulation
For patients with lumbar spinal stenosis who have not achieved adequate relief from injections, physical therapy, and medications, spinal cord stimulation offers a meaningful long-term option. SCS has demonstrated effectiveness for neurogenic claudication and the leg pain associated with lumbar stenosis, and it is particularly valuable for patients who are not ideal surgical candidates due to age, overall health, or the multilevel nature of their stenosis.
When Is Surgery Considered for Spinal Stenosis?
Surgery for spinal stenosis is typically considered when symptoms are severe enough to significantly limit daily function and have not responded to at least six weeks of appropriate non-surgical treatment. It is also considered urgently when there is progressive neurological deficit or when cervical stenosis has caused significant spinal cord compression that poses a risk of permanent neurological damage.
Non-surgical interventional management can be highly effective for the majority of stenosis patients and should always be fully explored before surgery is considered.
