Key Takeaways
- Spinal stenosis develops when the spaces inside the spine narrow and place pressure on nearby nerves.
- Age-related wear and tear, including osteoarthritis and disc changes, is the most common cause of spinal narrowing.
- Herniated discs, thickened ligaments, and bone spurs can each contribute to a tighter spinal canal.
- Certain risk factors, including age, prior spine injury, and hereditary conditions, may increase the likelihood of developing stenosis.
- Worsening back or leg symptoms should prompt a medical evaluation before the condition limits daily activities.
- West Michigan Pain provides comprehensive spinal stenosis care for patients in Big Rapids, MI, and residents can request an appointment to discuss treatment options for lasting relief.
What Is Spinal Stenosis?
Spinal stenosis is a narrowing of the spaces within the spine that can place pressure on the spinal cord and the nerves that branch off it. This narrowing most often occurs in the lower back, known as lumbar spinal stenosis, though it can also develop in the neck.
As the spinal canal narrows, nerves may become compressed or irritated, leading to pain, numbness, tingling, or weakness that can affect the back, buttocks, and legs. Symptoms often develop gradually and may worsen over time, which is why understanding the underlying causes is an important first step toward relief.
At West Michigan Pain, patients throughout the Big Rapids area receive personalized evaluations to identify the specific cause of their spinal narrowing and build a treatment plan around it.
How Spinal Stenosis Develops
Age-Related Changes That Narrow the Spine
The most common cause of spinal stenosis is degenerative change in the spine related to aging. According to AAOS OrthoInfo, degenerative changes in the spine are seen in up to 95 percent of people by age 50, and spinal stenosis most often occurs in adults over 60. As the spine ages, discs lose water content and flatten, joints thicken, and the space available for nerves gradually shrinks.
Herniated Discs and Degenerative Disc Disease
Spinal discs act as cushions between the vertebrae. When a disc degenerates or herniates, its inner material can push outward and encroach on the spinal canal, narrowing the space available for nerves and contributing to symptoms like sciatica.
Thickened Ligaments and Bone Spurs
Osteoarthritis in the spine can cause the ligaments that support the vertebrae to thicken and bulge into the spinal canal. Bone spurs, which are extra bone growths that form in response to joint wear, can also develop and press directly on nerve roots. Mayo Clinic notes that spinal stenosis is most commonly caused by these wear-and-tear changes related to osteoarthritis.
Common Conditions Linked to Spinal Narrowing
Spinal stenosis is often connected to other back conditions that West Michigan Pain treats regularly, including:
- Sciatica, which causes pain that radiates from the lower back through the buttock and down the leg.
- Sacroiliac joint pain, which affects the joint at the base of the spine.
- Degenerative disc disease, which can accelerate narrowing of the spinal canal.
- Radiculopathy, which refers to pain, tingling, or weakness caused by irritation of a spinal nerve root.
Patients can learn more about how these conditions are evaluated and treated on the Back Pain page.
Contributing Factors and How They Narrow the Spine
| Contributing Factor | How It Narrows the Spinal Canal |
|---|---|
| Osteoarthritis | Causes joints and ligaments in the spine to thicken and bulge inward. |
| Herniated or degenerated discs | Allows disc material to push into the space around the spinal cord. |
| Bone spurs | Adds extra bone growth that presses directly on nerve roots. |
| Congenital narrow canal | Leaves less baseline space, so smaller changes cause symptoms sooner. |
| Prior spine injury or surgery | Can alter spinal structure and accelerate degenerative changes. |
Risk Factors That May Increase the Likelihood of Spinal Stenosis
Several factors may raise a person's risk of developing spinal stenosis, including:
- Age, since most cases occur in adults over 60.
- A history of spine injury, prior back surgery, or repetitive strain from certain occupations.
- Arthritis or other conditions that affect joint and bone health.
- Being born with a naturally narrower spinal canal, known as congenital spinal stenosis.
While not everyone with these risk factors develops symptomatic stenosis, understanding them can help patients recognize when it may be time to seek an evaluation.
When Worsening Symptoms Should Prompt a Medical Evaluation
Because spinal stenosis symptoms tend to progress gradually, it can be easy to dismiss early signs as ordinary aches. However, patients who notice leg pain that worsens with walking, numbness that spreads, or reduced mobility should not wait to seek care. Left unaddressed, worsening spinal narrowing may continue to limit daily activities over time.
West Michigan Pain offers a range of treatment options for spinal stenosis, including nerve blocks and injections, spinal cord stimulation, and the mild® Procedure. The mild® Procedure is a short, minimally invasive outpatient treatment that restores space in the spinal canal without implants or opioids. These options may help reduce pain and improve function for appropriate candidates. Results vary from patient to patient, so a personalized evaluation is the best way to determine which options may help.

Frequently Asked Questions
What is the main cause of spinal stenosis?
The most common cause of spinal stenosis is age-related degenerative change in the spine, including osteoarthritis, disc thinning, and thickened ligaments that narrow the spinal canal over time.
Can spinal stenosis get worse over time?
Yes. Because spinal stenosis is often tied to ongoing degenerative changes, symptoms can progress gradually if the underlying narrowing is not addressed.
Is spinal stenosis hereditary?
Some people are born with a naturally narrower spinal canal, a condition known as congenital spinal stenosis, which can make them more likely to develop symptoms earlier in life.
