Beyond Back Pain: The Lesser-Known Symptoms of Spinal Stenosis

For many of us, we assume back pain is caused by lifting something heavy or sleeping in a bad position. But what if your back pain is accompanied by a host of other strange symptoms, like a tingling sensation in your legs, a feeling of weakness, or a cramping pain that only occurs when you are standing or walking? These may be the lesser-known signs of a common, age-related condition called spinal stenosis. While most people have heard of a slipped disc or sciatica, spinal stenosis is often overlooked, leading to a delayed diagnosis and unnecessary pain.

At Melbourne Spine Studio, our clinicians assess and manage a range of spinal conditions. This article provides general educational information about spinal stenosis, its symptoms, and the role of specialist assessment in diagnosis and management.

What is Spinal Stenosis?

The spine is a column of bones (vertebrae) with a hollow centre, called the spinal canal. The spinal cord and nerves run through this canal, and it provides them with protection and a clear pathway to the rest of the body. Spinal stenosis is a condition where the spinal canal narrows, putting pressure on the spinal cord and the nerves.

The narrowing can be caused by a variety of factors:

• Degenerative Arthritis: The most common cause. As we age, the small joints in the spine (the facet joints) can become arthritic, causing bony growths (bone spurs) that can encroach on the spinal canal.
• Spinal Disc Bulges: A bulging or herniated disc can protrude into the spinal canal and put pressure on the nerves.
• Thickened Ligaments: The ligaments that support the spine can thicken and harden over time, taking up space in the spinal canal.
• Spondylolisthesis: A condition where one vertebra slips forward over the one below it, which can narrow the spinal canal.

While it is most common in the lumbar (lower back) spine, it can also occur in the cervical (neck) spine.

The Symptoms: More Than Just Back Pain

The classic symptoms of spinal stenosis are often not just back pain. A person with spinal stenosis may have back pain, but some typical symptoms can include:

• Neurogenic Claudication: This is the most common and telling symptom. It is a cramping pain, numbness, or weakness in the legs and buttocks that occurs when standing or walking and is relieved by sitting or bending forward. It is often described as a feeling of “heavy” or “tired” legs.
• Radiating Pain: The pain can radiate from the lower back down into the buttocks and legs.
• Numbness or Tingling: You may experience a “pins and needles” sensation in your legs or feet.
• Loss of Sensation: In severe cases, you can experience a loss of sensation in your legs or feet, which can increase your risk of falls.

A key differentiator between spinal stenosis and other conditions is that the symptoms are often positional, with pain triggered by standing or walking and relieved by sitting or bending forward. This is because sitting widens the spinal canal, reducing pressure on the nerves.

The Importance of a Specialist’s Diagnosis

Without a diagnosis, it may be difficult to develop a targeted treatment plan that addresses the underlying cause of symptoms. Specialist assessment, often supported by imaging, is commonly used to confirm spinal stenosis and help distinguish it from other conditions with similar symptoms.

At your consultation, a spine specialist may conduct a thorough assessment, including:

• Detailed Medical History: We may ask about the onset of your pain, what triggers it, and what relieves it.
• Physical Examination: We may perform a series of tests to assess your muscle strength, sensation, and reflexes. We may also ask you to walk for a few minutes to see if your symptoms are triggered.
• Diagnostic Imaging: We may order a Magnetic Resonance Imaging (MRI) scan. An MRI is a common way to diagnose spinal stenosis, as it can provide clear, detailed images of the spinal canal, spinal cord, and nerves. It can also show whether there are any bulging discs, bone spurs, or thickened ligaments causing the narrowing.

From Diagnosis to Treatment

Management of spinal stenosis often begins with conservative treatment, depending on symptom severity and individual clinical factors.

• Physiotherapy: A physiotherapist can use a combination of exercises, stretches, and manual therapy to improve your core strength, flexibility, and posture.
• Medication: We may prescribe anti-inflammatory medications to reduce the swelling and pain.
• Epidural Steroid Injections: A spinal injection of a steroid into the epidural space can help to reduce the inflammation and swelling around the nerves, providing significant pain relief for many patients.
• Surgical Consideration: In severe cases, where symptoms significantly impact quality of life, and conservative treatments have not provided adequate relief, surgery may be considered as a management option, depending on individual circumstances. The goal of the surgery is to decompress the nerves by removing the bone spurs, disc material, or thickened ligaments that are causing the narrowing.

Living with the symptoms of spinal stenosis can be challenging, and a medical assessment may help identify appropriate management options. If symptoms persist or worsen, seeking assessment from an appropriately qualified healthcare professional or spine specialist may be appropriate.
