Disc Herniation & Slipped Disc Explained

Spine Health

Spinal discs are the shock-absorbing cushions that sit between each vertebra in your spine. Each disc has a tough outer ring (annulus fibrosus) and a soft, gel-like center (nucleus pulposus). When a disc becomes damaged — whether through injury, degeneration, or prolonged stress — it can bulge, crack, or rupture in ways that press on nearby nerves and cause significant pain.

Understanding the Terminology

The terms "slipped disc," "bulging disc," "herniated disc," and "ruptured disc" are often used interchangeably, but they describe different stages of disc damage:

What Causes Disc Herniation?

Disc herniations are most common in the lower back (lumbar spine) and neck (cervical spine). Causes include:

• Age-related degeneration — Discs naturally lose water content and elasticity with age, making them more prone to cracking
• Improper lifting — Using your back instead of your legs when lifting heavy objects creates enormous disc pressure
• Sudden trauma — A fall or auto accident can cause immediate disc herniation
• Repetitive strain — Jobs requiring repeated bending, twisting, or heavy lifting stress the discs over time
• Prolonged sitting — Sitting for extended periods increases disc pressure, particularly in the lumbar spine
• Excess body weight — Additional weight increases compressive forces on spinal discs

Symptoms of a Herniated Disc

Pain results when irritating substances are released from the disc tear and also when the displaced fragment touches or compresses a nearby nerve. Symptoms depend on where in the spine the herniation occurs:

Lumbar (Lower Back) Herniation

• Low back pain, often described as sharp or burning
• Sciatica — pain that radiates from the lower back through the buttock, down the leg to the foot
• Numbness and tingling in the leg or foot
• Weakness in the leg, making it difficult to stand on tiptoe

Cervical (Neck) Herniation

• Neck pain and stiffness
• Pain that radiates from the neck into the shoulder, arm, or hand
• Numbness or tingling in the arm, hand, or fingers
• Muscle weakness affecting grip strength

Disc Herniation vs. Degenerative Disc Disease

Disc herniation has some similarities to degenerative disc disease (DDD), and the two often coexist. DDD refers to the gradual deterioration of disc height and hydration that occurs with aging — it is not technically a "disease" but rather a description of wear patterns. A degenerated disc is more susceptible to herniation because its outer ring has become weaker and more brittle.

Chiropractic Care for Disc Problems

Many disc herniations respond well to conservative chiropractic treatment. Surgery is rarely the first answer — most patients achieve significant improvement without it.

Spinal Decompression & Adjustments

Targeted adjustments reduce spinal joint restriction and promote proper biomechanics. Flexion-distraction technique gently stretches the spine to create negative pressure within the disc, which can help draw the herniated material back toward its normal position.

Laser Therapy

Class IV laser therapy reduces inflammation around the compressed nerve root, accelerating the body's natural healing response and providing pain relief without medication.

Physical Rehabilitation

Core stabilization exercises are critical for disc patients. A strong core reduces the mechanical load on spinal discs and protects against re-injury. Dr. Zeaiter designs a progressive exercise program specific to each patient's condition.
