What it is

Degenerative disc disease describes the loss of disc height and hydration, as well as the sensitisation of the disc and nearby structures. This irritation of the surrounding nerves results in pain that radiates to the back and legs.

It is common with age. Common symptoms include chronic or recurring back pain, reduced flexibility, and numbness or tingling. However, some people have no symptoms at all. When painful, it causes deep axial back pain that flares with sitting or bending and settles with gentle walking.

Treatment often involves non-surgical methods like physical therapy, exercise, lifestyle changes, and pain medication to manage symptoms and strengthen the supportive muscles around the spine. Care reduces sensitivity, restores motion, and builds trunk and hip strength, allowing for reliable daily tasks and sleep.

What happens when it occurs

Disc load changes as height reduces. Inflammation can sensitise the area. Guarded movement increases stiffness. Graded movement and strength improve tolerance over time.

Common causes and risk factors

  • Age and family factors
  • Prolonged flexed sitting
  • Smoking and low physical activity
  • Previous back pain episodes

Who is most affected

Adults in working years and later life in Australia. Desk and manual workers are both present.

Typical symptoms

  • Deep low back pain
  • Worse with sitting and bending, eased by short walks
  • Occasional buttock referral without nerve signs

When to seek care

Urgently for progressive weakness, widespread numbness, saddle anaesthesia, or bladder or bowel change. Otherwise, when pain limits function.

How we diagnose

History, repeated movement testing, hip and thoracic screen, and neurological check. MRI is used for persistent or atypical cases or when procedures are considered.

Management

  • Education and position strategies
  • Mobility drills in tolerated directions
  • Trunk endurance and hip strength
  • Aerobic conditioning and work task planning
  • Medication and injections in selected cases

Rehabilitation milestones

Phase 1 weeks 0 to 2: pain control, position strategies, mobility in easy directions.

Phase 2 weeks 2 to 8: progressive endurance and strength, task practice.

Phase 3 months 2 to 6: longer days and sport skills by criteria.

Readiness to progress

  • Sleep not interrupted by pain
  • Daily range near normal
  • Strength and endurance targets met

Long-term care

  • Vary seated positions and device use
  • Keep two trunk sessions weekly
  • Plan recovery days during heavy blocks

Australia snapshot

  • Common findings on imaging in Australians with and without pain
  • Most improve without surgery when active care is followed
  • Return to work is usual with a structured plan

Latest insights

Direction matters. Use the movements that ease symptoms early and often.

Consistency beats intensity for disc-related pain.

Frequently Asked Questions

You cannot stop degenerative disc disease entirely. However, you can take steps to slow the wear of your spinal discs while lowering your pain levels. If you are diagnosed with this condition, your doctor should give you clear steps on living with DDD.

This wear and tear is a form of arthritis, which is where the cartilage in the spine joints begins to wear out. Regardless of the cause, it is well known that arthritis of the spine often increases with age for no identifiable reason.

Discs age like other tissues. Many people stay active and comfortable with the right plan in place.

Degenerative disc disease can progress at different speeds for different people. Several factors can influence how quickly it gets worse: The things we do every day, like sitting for long periods, not exercising enough, or lifting heavy objects incorrectly, can affect the progression of degenerative disc disease.

Avoid long fixed positions early. Restore bending gradually as symptoms settle.
