Spinal Stenosis

Narrowing of the Spinal Canal, Nerve Compression, and Treatment Options

When the Spine Narrows and Presses on Nerves

Spinal stenosis is a condition where the spaces within the spine become narrowed, placing pressure on nearby nerves. This narrowing of the spinal canal may lead to pain, numbness, tingling, weakness, or difficulty walking.

Some patients experience mild symptoms that develop gradually over time, while others may notice increasing leg pain, balance problems, or reduced walking tolerance affecting daily activities and mobility.

At Mash Spine & Orthopaedics, spinal stenosis treatment in Singapore is tailored to the patient’s symptoms, imaging findings, lifestyle, and functional needs. Treatment may include physiotherapy, medication, spinal injections, rehabilitation, minimally invasive procedures, or decompression surgery where appropriate.

Why Spinal Stenosis Develops Over Time

The spine contains a canal that protects the spinal cord and nerves. When this space becomes narrower, nerves passing through the canal may become crowded or compressed.

Spinal stenosis commonly develops gradually as part of ageing and wear-and-tear changes affecting the spine.

This narrowing may occur in:

Symptoms depend on which nerves are affected and how severe the narrowing becomes.

Common Causes of Spinal Stenosis

Several conditions may contribute to the narrowing of the spinal canal.

Arthritis and Degenerative Spine Changes

Wear-and-tear changes affecting the spine joints may lead to bone spur formation and thickening around the spinal canal.

Degenerative changes may contribute to:

Slipped (Herniated) Discs

Bulging or herniated discs may protrude into the spinal canal and compress nearby nerves.

This may contribute to:

Thickened Ligaments

The ligaments surrounding the spine may gradually thicken and stiffen over time.

As these tissues enlarge, they may reduce the available space within the spinal canal and contribute to nerve compression.

Spinal Injuries or Trauma

Fractures, falls, sports injuries, or accidents may alter spinal alignment and narrow the canal.

Symptoms may appear immediately or gradually after injury.

Scoliosis and Spinal Alignment Problems

Abnormal spinal curvature may change the alignment of the spinal canal and increase pressure on nerves.

Some patients with scoliosis may develop nerve-related symptoms later in life.

Lumbar Stenosis vs Cervical Stenosis

Spinal stenosis may affect different areas of the spine.

Lumbar Stenosis

Lumbar stenosis affects the lower back and is one of the most common forms of spinal stenosis.

Symptoms may include:

Many patients experience worsening symptoms when standing or walking for prolonged periods.

Cervical Stenosis

Cervical stenosis affects the neck region of the spine.

Symptoms may include:

In severe cases, cervical spinal cord compression may affect walking or fine motor control.

What Is Neurogenic Claudication?

Patients often experience:

Symptoms often improve when:

Some patients describe relief when leaning forward on a shopping cart while walking.

Symptoms That May Signal Spinal Stenosis

Symptoms often develop gradually and may worsen over time.

Common symptoms may include:

In severe cases, bladder or bowel symptoms may require urgent medical assessment.

What Could Be Causing Your Symptoms?

Several spine conditions may produce similar symptoms. A proper medical assessment helps identify the underlying cause.

Symptom	Possible Conditions
Difficulty walking	Lumbar stenosis, neurogenic claudication
Tingling or numbness	Nerve compression, spinal stenosis
Leg heaviness	Lumbar spinal canal narrowing
Arm pain or weakness	Cervical stenosis, cervical nerve compression
Lower back pain	Degenerative spine disease, slipped disc
Balance problems	Cervical spinal cord compression

This information is for general education only and should not be used to self-diagnose or self-treat. A medical assessment and imaging may be necessary to determine the exact cause of symptoms.

When Should You See a Spine Doctor?

Many patients initially dismiss spinal stenosis symptoms as part of ageing or fatigue. However, persistent or worsening symptoms may indicate progressive nerve compression.

You may wish to seek medical assessment if you experience:

Early assessment may help identify spinal canal narrowing before symptoms progress further.

How Spinal Stenosis Is Diagnosed

Because spinal stenosis shares symptoms with other spine conditions, accurate diagnosis is important.

Assessment usually begins with understanding:

A consultation may include:

Physical examination
Neurological testing
Reflex and strength assessment
Walking and posture evaluation
MRI scans
CT scans
X-rays

Imaging may help identify:

Spinal Stenosis Treatment Singapore

Treatment depends on:

Not all cases require surgery.

Physiotherapy for Spinal Stenosis

Physiotherapy may help:

Exercise programmes are usually tailored according to symptoms and functional goals.

Patients with lumbar stenosis may also benefit from guided rehabilitation and conditioning exercises.

Lifestyle and Activity Adjustments

Simple activity modifications may help reduce stress on the spine.

Recommendations may include:

Avoiding prolonged standing
Using supportive seating
Taking regular walking breaks
Gentle stretching
Low-impact exercise
Ergonomic adjustments

Remaining physically active may help support long-term mobility.

Decompression Surgery

When severe nerve compression affects walking, balance, strength, or daily activities, surgery may sometimes be considered.

Decompression surgery aims to create more space around compressed nerves within the spinal canal.

Procedures may include:

Spinal Injections

Image-guided spinal injections may sometimes be considered for:

Not all patients require injections.

Medication and Pain Relief

Medication may sometimes be used to:

Treatment recommendations depend on the patient’s symptoms and medical history

Living with Spinal Stenosis

Spinal stenosis can gradually affect mobility, independence, exercise tolerance, and quality of life.

Many patients benefit from:

Persistent symptoms should still be medically assessed, especially if walking becomes increasingly difficult.

Frequently Asked Questions About Spinal Stenosis

What is spinal stenosis?

Spinal stenosis is narrowing of the spinal canal that places pressure on nearby nerves or the spinal cord.

What causes spinal stenosis?

Common causes include arthritis, disc degeneration, slipped discs, thickened ligaments, and age-related wear-and-tear changes.

What is lumbar stenosis?

Lumbar stenosis refers to narrowing affecting the lower back, often causing leg pain, numbness, or difficulty walking.

What is cervical stenosis?

Cervical stenosis affects the neck region of the spine and may cause neck pain, arm symptoms, balance issues, or hand weakness.

What is neurogenic claudication?

Neurogenic claudication refers to leg pain, heaviness, or weakness that worsens while walking and improves with sitting or bending forward.

Does spinal stenosis always require surgery?

No. Many patients improve with physiotherapy, medication, rehabilitation, activity modification, or injections.

If you are experiencing back pain, neck pain, difficulty walking, leg heaviness, tingling, numbness, or symptoms related to spinal stenosis, schedule a consultation with Dr Mohd Mashfiqul Arafin Siddiqui at Mash Spine & Orthopaedics in Singapore.

As a spine specialist and spine doctor in Singapore, Dr Mash provides assessment and treatment for conditions affecting the spinal canal, spinal nerves, cervical spine, and lumbar spine.

A detailed assessment at our spine clinic can help identify the underlying cause of your symptoms and guide suitable treatment options, including physiotherapy, rehabilitation, spinal injections, minimally invasive procedures, or decompression surgery where appropriate.
