Lower back pain is one of the most common reasons people visit our Chiropractic clinic in the northern suburbs of Melbourne. Whether it’s a dull ache after a long day at the office, sharp pain after weekend gardening or discomfort from your daily commute – it can disrupt work, sleep, family time and your favourite activities. The good news? Most lower back pain is mechanical and not serious. It responds very well to conservative care like Chiropractic treatment, movement, posture correction and lifestyle changes. Understanding the common causes helps you take the right steps toward relief and prevention.
Why Is Lower Back Pain So Common?
The lumbar spine (lower back) supports most of your body weight, absorbs daily stresses, and enables movement. This combination makes it vulnerable to strain from modern lifestyles — prolonged sitting, repetitive movements, poor posture, and occasional heavy lifting.
Most Common Causes of Lower Back Pain
Here are the primary causes, from most frequent to less common:
- Muscle and Ligament Strains/Sprains
The most common cause. Sudden awkward movements, heavy lifting with poor technique, sneezing, or repetitive strain can overstretch or tear muscles and ligaments. Even everyday activities like bending to pick something up can trigger it, especially if your core is weak or you’ve been sedentary. - Disc Problems
- Bulging or Herniated Discs: The soft inner material of a disc pushes out and irritates nearby nerves (often causing sciatica).
- Degenerative Disc Disease: Discs lose hydration and cushioning with age, leading to pain and reduced flexibility.
- Facet Joint Issues
The small joints at the back of the spine can become inflamed, arthritic, or irritated from overuse, poor posture, or repetitive extension (arching backwards). - Sacroiliac (SI) Joint Dysfunction
The joints connecting your spine to your pelvis can become irritated, especially after pregnancy, falls, or uneven leg length/posture issues. - Spinal Stenosis
Narrowing of the spinal canal, more common with age, which can compress nerves and cause pain, especially with walking or standing. - Other Structural Issues
- Spondylolisthesis (one vertebra slipping forward)
- Scoliosis or postural imbalances
- Osteoarthritis of the spine
- Lifestyle and Contributing Factors
Many cases stem from or are worsened by:
- Prolonged sitting and poor ergonomics
- Weak core and glute muscles
- Excess weight
- Stress and tension (tightens back muscles)
- Smoking (reduces disc nutrition)
- Lack of regular movement
What Your Pain Pattern Might Tell You
- Pain worse with sitting/bending forward → Often disc-related
- Pain worse with standing/arching backwards → Often facet joint-related
- Morning stiffness that eases with movement → Could be joint or degenerative changes
- Radiating leg pain, numbness, or tingling → Possible nerve involvement (sciatica)
Note: Many people have a combination of these issues rather than one single cause.
When Lower Back Pain Might Be More Serious (Red Flags)
While rare, seek urgent medical care if you experience:
- Loss of bowel or bladder control
- Saddle numbness (inner thighs/groin)
- Progressive leg weakness
- Pain after major trauma
- Unexplained weight loss, fever, or history of cancer
How Chiropractic Care Help You
Unlike treatments that only mask symptoms, chiropractic care targets the underlying mechanical issues:
- Gentle spinal adjustments to restore movement and reduce joint irritation
- Soft tissue therapy to release tight muscles
- Flexion-distraction or decompression for disc problems
- Personalised rehabilitation exercises to strengthen your core and improve stability
- Postural and ergonomic advice tailored to your lifestyle (desk work, driving, etc.)
Most patients notice meaningful improvement within a few weeks through this conservative, drug-free approach.
Prevention: Protect Your Back Long-Term
- Move regularly — take breaks every 30–60 minutes
- Strengthen your core and posterior chain
- Lift with your legs, not your back
- Maintain good posture and ergonomic workstation setup
- Stay active with walking, swimming, or Pilates
- Keep a healthy weight and manage stress
