What is the Thecal Sac? Back Pain & Treatment

The spine, a complex structure responsible for both support and neural transmission, houses the thecal sac, a protective membrane surrounding the spinal cord and its associated nerve roots. Back pain, frequently evaluated by medical professionals specializing in orthopedics and neurology, can often be attributed to various conditions affecting the thecal sac. Magnetic Resonance Imaging, commonly known as MRI, serves as a crucial diagnostic tool in visualizing the thecal sac and identifying potential abnormalities, such as spinal stenosis or disc herniation, that impinge upon it. Therefore, understanding what is the thecal sac, its function, and the implications of its compromise is paramount for effective diagnosis and treatment of related back pain syndromes.

The Thecal Sac: Your Spine’s Unsung Protective Hero

The human spine, a marvel of biomechanical engineering, relies on a sophisticated system of protection for its most delicate components. At the heart of this protective system lies the thecal sac, also known as the dural sac.

It’s a critical structure that often goes unnoticed until problems arise.

This article delves into the importance of the thecal sac, exploring its definition, location, and primary functions.

Defining the Thecal Sac: The Dural Guardian

The thecal sac, or dural sac, is essentially a protective membrane. Think of it as a sturdy, fluid-filled bag that encases the spinal cord and its delicate nerve roots.

It’s formed by the dura mater, the outermost and toughest of the three meningeal layers surrounding the central nervous system.

This sac extends from the base of the skull down to the sacrum, providing a continuous sheath of protection.

Anatomical Location: Central to Spinal Integrity

The thecal sac resides within the spinal column, the bony structure that provides the primary support and protection for the spinal cord.

More specifically, it’s located within the vertebral canal, the hollow space formed by the vertebrae stacked upon one another.

This strategic positioning ensures that the spinal cord and nerve roots are shielded from potential injury and compression.

Primary Functions: Protection, Containment, and Support

The thecal sac serves several vital functions, all contributing to the overall health and well-being of the spine.

Protection of Neural Elements

The primary role is to protect the spinal cord and nerve roots from mechanical injury. The tough dural membrane acts as a physical barrier, cushioning these delicate structures against trauma.

Cerebrospinal Fluid (CSF) Containment

The thecal sac contains the cerebrospinal fluid (CSF). This clear, colorless fluid surrounds the spinal cord and brain, providing further cushioning and acting as a medium for nutrient transport and waste removal.

Structural Support

The thecal sac provides a degree of structural support to the spinal cord and nerve roots. This helps to maintain their proper alignment and prevent excessive movement, further reducing the risk of injury.

Anatomy of the Thecal Sac: Layers and Components

The thecal sac isn’t a singular entity, but rather a carefully constructed assembly of layers and spaces, each playing a vital role.

Understanding these components is crucial for appreciating how the thecal sac protects the spinal cord and nerve roots, and for grasping the implications of various spinal conditions.

The Meninges: A Three-Layered Defense

The thecal sac is essentially formed by the meninges, a set of three protective membranes that surround the spinal cord and brain. These layers, from outermost to innermost, are the dura mater, the arachnoid mater, and the pia mater.

Dura Mater: The Tough Outer Shield

The dura mater is the outermost layer, and as its name suggests ("dura" means hard or tough), it’s a thick, strong membrane composed of dense, fibrous connective tissue. It provides a durable, protective barrier against external forces and potential trauma.

Think of it as the spine’s first line of defense.

Arachnoid Mater: A Web of Protection

Beneath the dura mater lies the arachnoid mater, a delicate, web-like membrane. The space between the dura and arachnoid is called the subdural space.

The arachnoid mater is avascular, meaning it lacks blood vessels.

Pia Mater: The Intimate Embrace

The pia mater is the innermost layer, a thin, delicate membrane that adheres directly to the surface of the spinal cord and brain.

It’s highly vascular, carrying blood vessels that nourish the neural tissue. The space between the arachnoid and pia mater is called the subarachnoid space, and it’s filled with cerebrospinal fluid (CSF).

The Thecal Sac’s Relationship with Key Structures

The thecal sac isn’t just a container; it actively interacts with the spinal cord, nerve roots, and CSF.

The Spinal Cord and Nerve Roots: Protected Passengers

The primary role of the thecal sac is to house and protect the spinal cord and the nerve roots that emerge from it.

The spinal cord, a vital pathway for communication between the brain and the body, runs within the thecal sac. Nerve roots, which branch off from the spinal cord to innervate specific areas of the body, also reside within the sac’s protective embrace.

Cerebrospinal Fluid (CSF): The Cushioning Medium

The subarachnoid space, located between the arachnoid mater and the pia mater, is filled with cerebrospinal fluid (CSF).

This clear, colorless fluid serves as a cushion, protecting the spinal cord and brain from shocks and impacts.

CSF also plays a role in transporting nutrients and removing waste products from the central nervous system.

The thecal sac, therefore, provides a contained environment for the CSF to perform these critical functions.

The Thecal Sac and Its Neighbors: Key Anatomical Relationships

The thecal sac doesn’t exist in isolation; it’s intimately connected with surrounding structures that are essential for spinal health. Understanding these spatial relationships helps illuminate how the thecal sac functions and how disruptions can lead to various spinal conditions. The thecal sac’s neighboring structures must be in harmony for optimal function and pain-free movement.

The Spinal Cord and the Spinal Canal

The spinal cord, the body’s main information superhighway, resides within the thecal sac.

The thecal sac, in turn, is housed within the bony Spinal Canal (also known as the Vertebral Canal).

This canal is formed by the vertebrae, the individual bones of the spine, creating a protective tunnel for the delicate neural tissues. The spinal canal provides a crucial layer of defense against external trauma and injury.

The space between the thecal sac and the walls of the vertebral canal is called the epidural space, which contains fat and blood vessels, and is the location where epidural injections are administered.

Nerve Roots and the Intervertebral Foramen

Emerging from the spinal cord are nerve roots, which are responsible for transmitting signals between the spinal cord and the rest of the body.

These nerve roots must exit the spinal canal to reach their destinations.

They accomplish this by passing through openings called the intervertebral foramen located on each side of the vertebral column.

The thecal sac extends along with these nerve roots as they exit, providing a protective sleeve.

Any narrowing of the foramen, due to bone spurs or disc herniation, can compress the nerve root, leading to pain, numbness, or weakness in the areas supplied by that nerve.

The Cauda Equina

At the lower end of the spinal cord, around the level of the first or second lumbar vertebra, the spinal cord tapers into a bundle of nerve roots known as the cauda equina.

This name, meaning "horse’s tail" in Latin, aptly describes the appearance of these nerve roots as they descend through the thecal sac.

The thecal sac continues down to the sacrum, surrounding and protecting the cauda equina.

Compression of the cauda equina within the thecal sac, often due to a large disc herniation or tumor, can lead to a serious condition called Cauda Equina Syndrome. This syndrome requires immediate medical attention to prevent permanent neurological damage. Symptoms include severe lower back pain, bowel or bladder dysfunction, and numbness or weakness in the legs.

Cerebrospinal Fluid (CSF)

The thecal sac is filled with cerebrospinal fluid (CSF), a clear, colorless liquid that bathes and cushions the spinal cord and brain.

CSF serves multiple critical functions:

• Protection: It acts as a shock absorber, protecting the delicate neural tissues from injury.
• Nutrient Transport: It delivers nutrients to the spinal cord and removes waste products.
• Buoyancy: It reduces the effective weight of the brain and spinal cord, preventing compression of the lower structures.

CSF is constantly circulating within the thecal sac, ensuring a stable and supportive environment for the spinal cord and nerve roots. Disruptions in CSF flow or composition can indicate underlying neurological problems.

Spinal Canal (Vertebral Canal)

The spinal canal, also known as the vertebral canal, is the bony channel formed by the series of vertebral foramina in successive vertebrae. It extends from the base of the skull to the sacrum, providing a continuous protective pathway for the spinal cord and thecal sac.

The spinal canal’s dimensions are critical.

Narrowing of the spinal canal, a condition known as spinal stenosis, can compress the thecal sac and its contents, leading to pain, numbness, and weakness.

This narrowing can result from various factors, including age-related degeneration, arthritis, or disc herniations. Maintaining the integrity of the spinal canal is therefore paramount for preserving spinal health and neurological function.

Conditions Affecting the Thecal Sac: Causes of Compression and Inflammation

The thecal sac, while resilient, is vulnerable to a range of conditions that can compromise its integrity and function. These conditions often manifest through compression of the spinal cord and nerve roots, inflammation of the meningeal layers, or a combination of both. Understanding the various factors that can impact the thecal sac is crucial for recognizing potential issues and seeking timely intervention.

Understanding Thecal Sac Compression

Thecal sac compression occurs when space within the spinal canal is reduced, placing pressure on the spinal cord, nerve roots, and the thecal sac itself. This compression can arise from various sources, including:

• Structural Abnormalities: Congenital conditions or acquired deformities of the spine.

• Degenerative Changes: Age-related wear and tear leading to spinal stenosis or disc issues.

• Trauma: Injuries to the spine causing fractures or dislocations.

• Space-Occupying Lesions: Tumors, cysts, or abscesses within the spinal canal.

Spinal Stenosis: A Common Culprit

Spinal stenosis is a prevalent condition characterized by the narrowing of the spinal canal.

This narrowing can occur due to:

• Overgrowth of bone (bone spurs).
• Thickening of ligaments.
• Disc degeneration.

The reduced space compresses the spinal cord and nerve roots, leading to pain, numbness, and weakness. Cervical spinal stenosis (neck) and lumbar spinal stenosis (lower back) are the most common types.

Disc-Related Issues: Herniations and Bulges

Intervertebral discs act as cushions between the vertebrae.

However, these discs are prone to degeneration and injury, leading to:

• Herniated Disc (Slipped Disc): The soft inner core of the disc protrudes through the outer layer, potentially compressing the thecal sac and nerve roots.

• Bulging Disc: The disc extends beyond its normal boundaries but the outer layer remains intact. While not always symptomatic, a bulging disc can still contribute to compression.

Degenerative Disc Disease: Gradual Deterioration

Degenerative disc disease (DDD) encompasses the gradual deterioration of the intervertebral discs. As discs lose hydration and elasticity, they become more susceptible to:

• Tears.
• Bulges.
• Herniations.

DDD can contribute to spinal stenosis and nerve compression.

Spondylolisthesis: Vertebral Instability

Spondylolisthesis involves the slippage of one vertebra over another. This instability can compress the spinal cord and nerve roots, leading to pain and neurological symptoms. The condition is graded based on the severity of the slippage, with higher grades indicating greater instability and compression.

Spondylosis: Osteoarthritis of the Spine

Spondylosis refers to osteoarthritis of the spine, characterized by the breakdown of cartilage in the facet joints. This degeneration can lead to:

• Bone spur formation.
• Narrowing of the spinal canal.
• Compression of neural elements.

Cauda Equina Syndrome: A Medical Emergency

Cauda equina syndrome (CES) is a severe condition involving compression of the cauda equina, a bundle of nerve roots at the lower end of the spinal cord.

CES is a medical emergency requiring immediate intervention to prevent permanent neurological damage.

Symptoms include:

• Severe lower back pain.
• Bowel or bladder dysfunction.
• Saddle anesthesia (numbness in the groin and inner thighs).
• Weakness in the legs.

Inflammatory Conditions: Meningitis and Arachnoiditis

Inflammation of the meninges, the membranes surrounding the brain and spinal cord, can directly affect the thecal sac.

• Meningitis: Inflammation of the meninges, often caused by infection. Meningitis can lead to swelling and increased pressure within the spinal canal.

• Arachnoiditis: Inflammation of the arachnoid mater, the middle layer of the meninges. Arachnoiditis can cause chronic pain and neurological deficits due to scarring and nerve root entrapment.

Spinal Tumors: Space-Occupying Lesions

Spinal tumors, whether benign or malignant, can occupy space within the spinal canal. These tumors can directly compress the spinal cord, nerve roots, and thecal sac, leading to a range of neurological symptoms. The severity of symptoms depends on the tumor’s:

• Location.
• Size.
• Growth rate.

Epidural Abscess: A Source of Compression

An epidural abscess is a collection of pus between the dura mater and the vertebral column. This abscess can compress the spinal cord and nerve roots, causing:

• Severe pain.
• Fever.
• Neurological deficits.

Prompt diagnosis and treatment, often involving surgical drainage and antibiotics, are crucial to prevent permanent damage.

Recognizing the Signs: Symptoms of Thecal Sac Issues

Conditions affecting the thecal sac can manifest in various ways, often signaling underlying spinal problems. Recognizing these symptoms early is crucial for timely diagnosis and intervention. While symptoms can vary based on the specific condition and its severity, certain patterns commonly emerge, indicating potential issues within the thecal sac.

Back Pain: A Common Indicator

Back pain is perhaps the most prevalent symptom associated with spinal conditions affecting the thecal sac. While back pain alone doesn’t definitively point to a thecal sac issue, its presence, especially when accompanied by other neurological symptoms, warrants further investigation.

The nature of back pain can vary. It may be a dull, constant ache or a sharp, shooting pain that intensifies with movement. Sometimes, the pain is localized to the lower back. At other times, it may radiate to other areas, such as the hips or buttocks.

It is important to distinguish between acute and chronic back pain. Acute pain is often related to a specific injury or event. Chronic pain persists for longer than three months. Chronic back pain is more likely to indicate an underlying spinal condition, such as spinal stenosis or degenerative disc disease.

Radiculopathy: Nerve Root Compression

Radiculopathy refers to a set of symptoms that occur when a nerve root is compressed or irritated. This compression can directly affect the thecal sac by impacting the nerve roots that emerge from the spinal cord within the sac.

The most common symptoms of radiculopathy include:

• Pain: A sharp, shooting pain that radiates along the path of the affected nerve.

• Numbness: A loss of sensation in the area served by the nerve.

• Weakness: Difficulty moving or controlling muscles innervated by the nerve.

• Tingling: A pins-and-needles sensation.

Radiculopathy can occur in different parts of the spine, leading to varying symptoms. Cervical radiculopathy affects the neck and upper extremities, causing pain, numbness, and weakness in the arms and hands. Lumbar radiculopathy affects the lower back and legs, leading to sciatica.

Sciatica: Pain Along the Sciatic Nerve

Sciatica is a specific type of radiculopathy that involves the sciatic nerve. This is the longest and thickest nerve in the body. It originates in the lower back and runs down the back of each leg.

Sciatica typically presents as a sharp, shooting pain that radiates from the lower back down the buttock and leg. The pain may be constant or intermittent and can worsen with prolonged sitting or standing.

In addition to pain, sciatica can also cause numbness, tingling, and weakness in the affected leg and foot. In severe cases, it may even lead to loss of bowel or bladder control, a condition that requires immediate medical attention.

Diagnosis: Imaging Techniques to Visualize the Thecal Sac

Conditions affecting the thecal sac can manifest in various ways, often signaling underlying spinal problems. Recognizing these symptoms early is crucial for timely diagnosis and intervention. While symptoms can vary based on the specific condition and its severity, certain patterns commonly emerge. To accurately pinpoint the source of these issues, advanced imaging techniques are essential.

The Role of Imaging in Assessing Thecal Sac Health

When neurological symptoms suggest a potential problem with the thecal sac or surrounding structures, diagnostic imaging becomes paramount. These tools allow clinicians to directly visualize the spinal cord, nerve roots, and thecal sac itself, identifying any abnormalities causing compression, inflammation, or other issues. Without these imaging modalities, accurate diagnosis and targeted treatment would be significantly more challenging.

MRI (Magnetic Resonance Imaging): A Detailed View

Magnetic Resonance Imaging (MRI) is often the first-line imaging technique employed to evaluate the thecal sac. MRI utilizes strong magnetic fields and radio waves to generate detailed, cross-sectional images of the spine.

Advantages of MRI

• Superior Soft Tissue Resolution: MRI excels at differentiating between various soft tissues, including the spinal cord, nerve roots, intervertebral discs, and ligaments. This allows for precise identification of herniated discs, spinal cord compression, and other soft tissue abnormalities.

• Non-Invasive: MRI is a non-invasive procedure, meaning it doesn’t involve the use of ionizing radiation (like X-rays or CT scans). This makes it a safe option for repeated imaging, especially in patients with chronic spinal conditions.

• Multiplanar Imaging: MRI can acquire images in multiple planes (axial, sagittal, coronal), providing a comprehensive three-dimensional view of the spine and surrounding structures.

What MRI Reveals

MRI can effectively visualize:

• Thecal Sac Compression: Identifying the cause and extent of thecal sac compression, whether due to disc herniation, spinal stenosis, or other space-occupying lesions.
• Spinal Cord Abnormalities: Detecting spinal cord tumors, inflammation (myelitis), or other structural changes.
• Nerve Root Impingement: Visualizing nerve root compression or inflammation, often the source of radicular pain.
• Ligamentous Injuries: Identifying tears or other damage to the spinal ligaments, which can contribute to spinal instability.

Myelogram: Enhanced Visualization with Contrast Dye

A myelogram is an imaging technique that involves injecting a contrast dye into the space surrounding the spinal cord (the subarachnoid space). This dye enhances the visualization of the spinal cord, nerve roots, and thecal sac on X-ray images or CT scans.

How Myelography Works

The contrast dye outlines the spinal cord and nerve roots, making them more visible on imaging. This is particularly useful for identifying areas of compression or obstruction that may not be as clearly seen on standard MRI scans.

When is Myelography Used?

Myelography is typically reserved for situations where:

• MRI is Contraindicated: Patients with certain metallic implants or other contraindications may not be able to undergo MRI.
• MRI Findings are Inconclusive: In some cases, MRI findings may be ambiguous, and myelography can provide additional information to clarify the diagnosis.
• Pre-Operative Planning: Myelography can be helpful for surgical planning, providing a detailed roadmap of the spinal anatomy and any areas of compression.

Considerations with Myelography

While myelography can be a valuable diagnostic tool, it is an invasive procedure that carries some risks, including headache, infection, and allergic reaction to the contrast dye. Therefore, it is typically used when other non-invasive imaging modalities are not sufficient.

In conclusion, while MRI serves as the mainstay for visualizing spinal structures, including the thecal sac, Myelography can be an important alternative. Ultimately, selecting the right diagnostic approach relies on various factors like symptom severity, patient medical history, and potential contraindications.

Treatment Options: Managing and Relieving Thecal Sac Compression

Conditions affecting the thecal sac can manifest in various ways, often signaling underlying spinal problems. Recognizing these symptoms early is crucial for timely diagnosis and intervention. While symptoms can vary based on the specific condition and its severity, certain patterns commonly emerge. Once diagnosed, a range of treatment options is available, tailored to the specific condition and individual patient needs.

These treatments span from conservative measures aimed at symptom management to surgical interventions designed to alleviate thecal sac compression directly. The selection of the most appropriate treatment strategy is a collaborative process between the patient and their healthcare provider, considering factors such as the severity of the condition, the patient’s overall health, and their preferences.

Conservative Management: Easing Symptoms and Promoting Healing

Conservative treatments are often the first line of defense for managing thecal sac compression. These non-surgical approaches aim to reduce inflammation, alleviate pain, and improve function. While they may not directly address the underlying cause of the compression, they can provide significant relief and allow the body to heal.

Physical therapy plays a crucial role in conservative management. Targeted exercises can strengthen supporting muscles, improve posture, and increase flexibility, thereby reducing stress on the spine and thecal sac. Physical therapists can also employ manual therapy techniques to release muscle tension and improve joint mobility.

Lifestyle modifications, such as weight management and ergonomic adjustments, can also contribute to symptom relief. Reducing excess weight decreases the load on the spine, while ergonomic adjustments at work and home can minimize strain and promote proper posture.

Epidural Steroid Injections: Targeted Inflammation Reduction

Epidural steroid injections (ESIs) are a common interventional pain management technique used to reduce inflammation and pain associated with thecal sac compression. These injections deliver corticosteroids directly into the epidural space, the area surrounding the thecal sac.

The corticosteroids act as potent anti-inflammatory agents, reducing swelling and irritation around the nerve roots and thecal sac. This, in turn, can alleviate pain, numbness, and other neurological symptoms.

It’s important to note that ESIs provide temporary pain relief and are not a long-term solution for the underlying condition. They are often used in conjunction with other conservative treatments to manage symptoms and facilitate rehabilitation. The efficacy of ESIs can vary, and repeated injections may not be recommended due to potential side effects.

Pain Medications: Aiding Symptom Control

Pain medications play a vital role in managing the discomfort associated with thecal sac compression. A variety of medications are available, each with its own mechanism of action and potential side effects. The choice of medication depends on the severity of the pain, the individual’s medical history, and other factors.

Analgesics, such as acetaminophen, are often used for mild to moderate pain relief. They work by reducing pain signals in the brain.

Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, reduce both pain and inflammation. However, long-term use of NSAIDs can increase the risk of gastrointestinal problems and cardiovascular issues.

In cases of severe pain, opioid analgesics may be prescribed. However, opioids carry a risk of addiction and should be used cautiously and under close medical supervision.

Surgical Interventions: Decompressing the Thecal Sac

When conservative treatments fail to provide adequate relief, and thecal sac compression significantly impacts quality of life, surgical intervention may be considered. Surgical procedures aim to decompress the thecal sac, relieving pressure on the spinal cord and nerve roots.

The specific surgical approach depends on the cause and location of the compression. Several surgical techniques are commonly employed:

Laminectomy: Widening the Spinal Canal

Laminectomy involves removing a portion of the lamina, the bony arch that forms the back of the vertebral segment. This widens the spinal canal, creating more space for the spinal cord and nerve roots and relieving compression.

Discectomy: Addressing Herniated Discs

Discectomy involves removing the portion of a herniated disc that is pressing on the thecal sac or nerve roots. This procedure can be performed using open or minimally invasive techniques.

Foraminotomy: Enlarging Nerve Root Openings

Foraminotomy involves enlarging the intervertebral foramen, the opening through which nerve roots exit the spinal canal. This can relieve pressure on nerve roots caused by bone spurs or other obstructions.

Microdiscectomy: Minimally Invasive Disc Removal

Microdiscectomy is a minimally invasive technique for removing herniated disc material. It involves using a small incision and specialized instruments to access and remove the disc fragment.

Decompression Surgery: A Broad Approach

Decompression surgery is a general term that encompasses various surgical procedures aimed at relieving pressure on the spinal cord and nerve roots. The specific technique used depends on the individual patient’s condition.

Surgical intervention is generally considered when there is significant neurological compromise, such as progressive weakness or bowel/bladder dysfunction. While surgery can be effective in relieving thecal sac compression, it also carries risks, such as infection, bleeding, and nerve damage. The decision to undergo surgery should be made in consultation with a qualified spine surgeon, carefully weighing the potential benefits and risks.

Key Concepts: Understanding Compression and Inflammation

Conditions affecting the thecal sac can manifest in various ways, often signaling underlying spinal problems. Recognizing these symptoms early is crucial for timely diagnosis and intervention. While symptoms can vary based on the specific condition and its severity, certain patterns consistently emerge, highlighting the pivotal roles of compression and inflammation.

Understanding Compression’s Impact

Compression, in the context of the thecal sac, refers to the application of pressure on the spinal cord, nerve roots, or the thecal sac itself. This pressure can stem from a variety of sources, each with distinct implications.

Sources of Compression

A herniated disc, for instance, can directly impinge upon the thecal sac or a nerve root exiting the spinal column. Spinal stenosis, characterized by the narrowing of the spinal canal, creates a constricted space, leading to generalized compression. Tumors, whether benign or malignant, represent space-occupying lesions that exert pressure on surrounding neural structures.

Consequences of Untreated Compression

Regardless of the etiology, prolonged or severe compression can lead to a cascade of detrimental effects. Nerve function can be impaired, resulting in pain, numbness, and weakness in the affected areas. In extreme cases, such as with Cauda Equina Syndrome, compression of the cauda equina (the bundle of nerves at the lower end of the spinal cord) constitutes a medical emergency, potentially leading to permanent neurological damage if left untreated.

Inflammation’s Role in Spinal Pathology

Inflammation is the body’s natural response to injury or infection. However, in the context of spinal conditions, it can become a chronic and debilitating factor.

The Inflammatory Cascade

When the thecal sac or surrounding structures are damaged or irritated, the body initiates an inflammatory cascade. This involves the release of various chemical mediators that contribute to swelling, pain, and tissue damage.

Manifestations of Inflammation

Inflammation can directly irritate nerve roots, exacerbating pain and neurological symptoms. Moreover, chronic inflammation can contribute to the degeneration of spinal tissues, perpetuating a cycle of pain and dysfunction. Conditions such as arachnoiditis, an inflammation of the arachnoid mater (one of the membranes surrounding the spinal cord), exemplify the profound impact of inflammation on thecal sac health.

So, there you have it – a breakdown of what the thecal sac is, its role in protecting your spinal cord, and how issues affecting it can lead to back pain. If you’re experiencing persistent back pain, especially with radiating symptoms, it’s always best to consult with a healthcare professional. They can properly diagnose the cause and recommend the most appropriate treatment plan for you.
