What Is a Concentric Disc Bulge (and Can Chiropractic Care Help)?
A concentric disc bulge is a common but often misunderstood spinal condition that can contribute to back pain, stiffness, and reduced mobility. Back pain is one of the most common reasons people seek care globally. It is recognized as the leading cause of disability, affecting an estimated 619 million people in 2020.
While the term might sound intimidating, understanding what a concentric disc bulge is – and how chiropractic care may help – can make a big difference in managing symptoms and maintaining spinal health.
What Is a Concentric Disc Bulge?
Your spine is made up of a series of bones called vertebrae, separated by cushion-like intervertebral discs. These discs act as shock absorbers, allowing flexibility while protecting the spinal cord and nerves.
Each disc has two main parts:
Nucleus pulposus - a gel-like center that provides cushioning
Annulus fibrosus - a tough, outer ring that keeps the disc stable and contained
A disc bulge occurs when the outer fibers of the disc weaken or stretch, causing the disc to extend slightly beyond its normal boundary.
In a concentric disc bulge, this extension happens evenly around the entire disc like an inflated tire expanding uniformly. This is different from other disc problems such as:
Eccentric or asymmetric bulge: one side protrudes more than the other
Disc herniation: inner gel pushes through a tear in the outer ring and may press on nerves
A concentric disc bulge is generally considered a mild form of disc degeneration and often an early stage in the process. While it may not always cause symptoms, it can lead to discomfort if it affects nearby structures or alters spinal movement.
Common Causes and Risk Factors
Concentric disc bulges typically develop over time rather than from a single injury. Common contributors include:
Natural aging: discs lose hydration and elasticity with time
Poor posture: slouching or prolonged sitting increases spinal stress
Repetitive strain: frequent bending, twisting, or lifting
Sedentary lifestyle: weak core/back muscles reduce spinal support
Trauma: sudden accidents or improper lifting
It’s also true that many people have disc bulges without symptoms – MRI studies often find asymptomatic bulges. Symptoms usually arise when inflammation or nerve irritation develops.
Symptoms of a Concentric Disc Bulge
Symptoms depend on where the bulge occurs and whether nearby nerves are irritated.
Common signs may include:
Dull or aching pain in the neck or lower back
Pain radiating into the shoulders, arms, buttocks, or legs (if nerves are compressed)
Numbness, tingling, or weakness in the extremities
Stiffness and reduced range of motion, especially after sitting or standing for long periods
If the bulge is mild and doesn’t press on nerves, you might notice tightness or stiffness rather than sharp pain. However, if nerve compression occurs, symptoms can become more intense or widespread.
Seek urgent care if pain is severe or accompanied by loss of bladder or bowel control.
How Chiropractic Care May Help
Chiropractic care focuses on optimizing spinal alignment and restoring proper movement. Because a concentric disc bulge affects both structure and motion, Charleston chiropractors use non-invasive strategies to reduce pressure, ease discomfort, and support healing.
1) Spinal Adjustments
Gentle, controlled chiropractic adjustments help restore joint mobility and alignment, which may reduce mechanical stress on the disc and improve flexibility.
2) Soft Tissue Therapy
Myofascial release and trigger point work can relax tight muscles that contribute to abnormal loading on the spine.
3) Posture & Ergonomics
Coaching on sitting, standing, lifting, and sleep positions helps limit strain on affected segments.
4) Exercise & Lifestyle Guidance
Targeted core and hip strengthening, mobility work, walking programs, hydration, and movement breaks complement hands-on care.
In a 2022 BMJ Open retrospective cohort study of U.S. adults with newly diagnosed lumbar disc herniation/radiculopathy, those receiving chiropractic spinal manipulation had reduced odds of undergoing lumbar discectomy over 1 and 2 years compared with matched patients receiving other care. While observational (not randomized), this supports conservative care as a viable pathway for many patients.
Chiropractic care doesn’t “cure” a disc bulge, but it often helps reduce pain, improve function, and support natural recovery. Sometimes, delaying or avoiding more invasive options.
Recovery and Prevention Tips
Recovering from a concentric disc bulge and preventing flare-ups usually involves combining professional care with self-management:
Stay active: Gentle walking and mobility work keep discs nourished and reduce stiffness
Strengthen your core: Ab and back endurance exercises improve spinal support
Mind your posture: Neutral spine when sitting, standing, and lifting; consider ergonomic upgrades
Avoid long sitting: Stand, stretch, or walk every 30–45 minutes
Lift smart: Bend at the hips/knees, keep objects close, avoid twisting
Hydrate & recover: Discs rely on water content; prioritize sleep and stress management
Weight management: Reduces load on the lumbar spine
Regular chiropractic check-ins with Cypress Chiropractic & Wellness, a chiropractor in Charleston SC, can help track progress, fine-tune exercises, and maintain mobility.
When to Seek Medical Attention
Most concentric disc bulges respond to conservative care, but get prompt medical evaluation if you experience:
Sudden, severe or worsening pain unresponsive to rest
Progressive numbness, weakness, or tingling in a limb
Bladder/bowel changes or saddle anesthesia (possible cauda equina syndrome, a medical emergency)
Chiropractors routinely collaborate with primary care, physical therapy, and spine specialists. If needed, imaging (e.g., MRI) can clarify the diagnosis and guide next steps.
A Balanced Approach to Spinal Health
A concentric disc bulge doesn’t automatically mean chronic pain or surgery. For many people, it’s a manageable finding that improves with conservative, non-invasive care.
Chiropractic offers a practical, whole-person approach, addressing alignment, movement, and habits, so you can move with less pain and more confidence. If you’re dealing with persistent neck or back discomfort, consider a qualified Charleston chiropractor for an individualized plan that supports long-term spinal health.

Frequently Asked Questions
Is a disc bulge a serious problem?
A disc bulge isn’t always serious. Many cases cause little or no pain. However, if the bulge presses on spinal nerves, it can lead to significant discomfort or mobility issues that require professional care.
What are the four stages of disc bulge?
The four stages are: disc degeneration, prolapse (bulging), extrusion (herniation), and sequestration (fragmentation). Each stage reflects increasing damage to the disc structure and potential nerve involvement.
What is the L4 L5 concentric disc bulge?
An L4 L5 concentric disc bulge means the disc between the fourth and fifth lumbar vertebrae is bulging evenly around its edges. This area is a common site of lower back pain because it bears much of the body’s weight and movement.
What happens if a bulging disc goes untreated?
If untreated, a bulging disc may worsen over time, leading to chronic pain, nerve irritation, or reduced mobility. Early conservative care can help prevent further degeneration.
At what point does a bulging disc require surgery?
Surgery is usually considered only when conservative treatments fail and symptoms like severe pain, weakness, or loss of bladder or bowel control appear. Most people find relief through non-surgical options such as chiropractic care, physical therapy, and exercise.
