What Is a Disc Bulge or Disc Injury?

A disc bulge or disc injury occurs when one of the spinal discs—the cushions between the vertebrae—loses its normal shape or integrity. This can place stress on surrounding joints, ligaments, and nerves.

While a disc bulge can lead to sciatica if it presses on a nerve root, many people do not experience leg pain at all. Instead, symptoms may present as:

• Deep, aching low back pain

• Pain referring into the hip, groin or lower abdomen

• Stiffness or locking in the lower back

• Difficulty sitting or bending forward

Disc-related pain is often much worse with sitting, driving and forward bending and may feel better when lying down.  

Common Causes of Disc Injury

Disc injuries can occur following trauma, such as a lifting accident or fall. However, the most common cause is prolonged sitting, which places sustained pressure on spinal discs.

This is particularly relevant for:

• FIFO workers driving long distances or operating machinery for extended shifts

• Office workers with poor postural variation

• Long-distance drivers

Disc injuries are also more prevalent in flexible or hypermobile individuals, where connective tissue laxity places additional strain on the discs.

Disc Injuries and the Gym

Low back pain is the most common injury seen in the gym, and certain exercises have been linked to disc bulges when performed incorrectly or too frequently under load.

Exercises commonly associated with disc injury include:

• Deadlifts

• Deep squats

• Repetitive flexion-based lifting

When combined with fatigue, poor technique, or inadequate recovery, these movements can overload the disc—especially in flexible individuals.

How Disc Pain Feels Different

Disc pain (discogenic pain) often behaves differently from other causes of back pain:

• Pain is usually worse with sitting and bending forward

• Relief is often found lying flat

• Pain may feel deep, internal, or hard to localise

• Movements that load the disc reproduce symptoms

This pattern is different from facet joint pain, which is typically worse with standing, extension, or twisting.

Our experience allows us to accurately differentiate discogenic pain from facet joint pain, ensuring the correct treatment pathway from the start—so you don’t waste time on ineffective care.

Chiropractic Care for Disc Bulge and Disc Injury

When appropriate, chiropractic adjustments can be very effective in relieving disc-related back pain and restoring movement. Treatment is tailored to reduce disc pressure while supporting surrounding structures.

Care may include:

• Gentle, specific chiropractic adjustments

• Dry needling to reduce muscle spasm

• Soft tissue therapy to unload the spine

• Activity modification advice

In disc injuries, rest is critical. Lying down to unload the disc, combined with short, frequent walks, helps maintain mobility without aggravating symptoms.

Imaging and Advanced Investigation

If pain is persistent or clearly disc-related, imaging may be required. In some cases, a SPECT bone scan may be recommended to identify the exact pain generator—particularly if symptoms are entirely discogenic and not responding as expected.

Medication and Recovery Strategy

Medication can play an important short-term role in managing acute disc pain and allowing movement to return. This is often followed by:

• A guided, progressive strength program

• Restoration of full movement

• Long-term strategies to protect the disc

Strength training is reintroduced carefully to retain function without re-injury.

Experience Matters in Disc Injuries

Disc injuries require clinical judgement, patience, and experience. Knowing when to rest, when to treat, when to image, and when to modify training is critical.

Our experience helps:

• Identify the true source of your pain

• Differentiate disc pain from joint pain

• Choose the most effective treatment approach

• Prevent unnecessary delays or setbacks
