Lower back pain is one of the most common health complaints worldwide, affecting people of all ages and lifestyles. Whether it strikes suddenly after lifting something heavy or builds gradually over months of poor posture, understanding lower back pain causes is the first step toward effective relief. At Reviva Physio & Rehab, we see patients every week who are searching for answers about their discomfort. In this guide, we’ll walk you through the most common triggers, practical treatment options, and clear signs that it’s time to book an appointment with a physiotherapist.
Why Understanding the Cause Matters
Lower back pain isn’t a single condition — it’s a symptom that can stem from many different sources, ranging from simple muscle strain to more complex spinal issues. Treating the pain without identifying its root cause often leads to temporary relief followed by repeated flare-ups. That’s why a proper assessment is so important. Once you know what causes lower back pain in your specific case, you and your physiotherapist can build a treatment plan that addresses the actual problem rather than just masking the symptoms.
8 Common Causes of Lower Back Pain
1. Muscle or Ligament Strain
The most frequent cause of lower back pain is a simple strain. Sudden awkward movements, heavy lifting, or repetitive bending can overstretch or tear muscles and ligaments supporting the spine. This often results in stiffness, localized soreness, and muscle spasms that ease within a few days to a few weeks with proper care.
2. Poor Posture
Spending long hours hunched over a desk, phone, or steering wheel places continuous strain on the lower spine. Over time, poor posture weakens supporting muscles and shifts the natural curve of the spine, leading to chronic discomfort that many people mistake for a “normal” part of desk work.
3. Herniated or Bulging Discs
The discs between your vertebrae act as cushions. When the soft inner material pushes through a weakened outer layer, it can press on nearby nerves, causing pain that radiates into the buttocks or legs — a condition often described as sciatica.
4. Degenerative Disc Disease
As we age, spinal discs naturally lose hydration and elasticity, reducing their shock-absorbing ability. This gradual wear and tear is a common contributor to persistent lower back pain, particularly in adults over 40.
5. Sciatica
Sciatica occurs when the sciatic nerve — which runs from the lower back down each leg — becomes compressed or irritated. It typically causes sharp, shooting pain, tingling, or numbness on one side of the body.
6. Spinal Stenosis
This condition involves narrowing of the spinal canal, which puts pressure on the nerves. It’s more common in older adults and often causes pain that worsens with standing or walking and improves with sitting or bending forward.
7. Poor Core Strength
Weak abdominal and back muscles fail to support the spine, forcing other structures to compensate. This imbalance is a frequently overlooked contributor to recurring lower back pain, especially in people who are largely sedentary.
8. Injury or Trauma
Falls, sports injuries, or car accidents can cause fractures, sprains, or soft tissue damage that result in acute lower back pain. These injuries sometimes require imaging and a structured rehabilitation plan to heal correctly.
Effective Lower Back Pain Treatment Options
The right lower back pain treatment depends heavily on the underlying cause, but several approaches are widely effective:
- Rest and activity modification – Short-term rest can help acute strains, but prolonged inactivity often slows recovery. Staying gently active is usually recommended.
- Heat and cold therapy – Cold packs reduce inflammation in the first 48 hours, while heat therapy relaxes tight muscles afterward.
- Stretching and strengthening exercises – Targeted exercises improve flexibility and build core stability, reducing strain on the spine.
- Manual therapy – Hands-on techniques like soft tissue mobilisation and joint manipulation can relieve tension and improve mobility.
- Posture correction – Ergonomic adjustments at work and home prevent recurring strain.
- Pain management – Over-the-counter anti-inflammatories may help short-term, though they don’t address the underlying cause.
- Structured rehabilitation programs – For chronic or recurring pain, a personalised recovery plan is often the most effective long-term solution.
The Role of Physiotherapy in Recovery
Physiotherapy for lower back pain is widely regarded as one of the most effective, non-invasive treatment approaches available. A physiotherapist doesn’t just treat the symptom — they assess your posture, movement patterns, muscle strength, and flexibility to identify the true source of your pain.
Typical physiotherapy interventions include:
- A thorough physical assessment and movement screening
- Manual therapy to relieve muscle tension and joint stiffness
- A customised exercise program to strengthen the core and improve flexibility
- Postural and ergonomic education to prevent recurrence
- Gradual return-to-activity guidance for sports or physically demanding jobs
Unlike medication, which only masks discomfort, physiotherapy works to correct the mechanical issues causing the pain — helping reduce the likelihood of it returning.
When to See a Physiotherapist for Back Pain
Many people wait too long before seeking professional help, often hoping the pain will go away on its own. While mild, short-lived discomfort can sometimes resolve with rest, there are clear signs that indicate it’s time to book an assessment.
Knowing when to see a physio for back pain can prevent a minor issue from becoming a chronic one. Consider booking an appointment if you experience:
- Pain lasting longer than a week or two without improvement
- Pain that radiates down one or both legs
- Numbness, tingling, or weakness in the legs or feet
- Difficulty standing up straight or performing daily activities
- Pain following a fall, accident, or injury
- Recurring episodes of lower back pain
- Pain that disrupts sleep or worsens at night
- Back pain accompanied by unexplained weight loss or fever (seek medical attention promptly)
Early intervention often leads to faster, more complete recovery and reduces the risk of the condition becoming chronic.

Frequently Asked Questions (FAQs)
1. What is the most common cause of lower back pain?
Muscle or ligament strain is the most common cause, typically resulting from heavy lifting, sudden movements, or poor posture over time.
2. How long does lower back pain usually last?
Acute lower back pain often improves within a few days to six weeks with proper care. If pain persists beyond this, it’s considered chronic and should be evaluated by a professional.
3. Can physiotherapy really help with lower back pain?
Yes. Physiotherapy addresses the underlying mechanical causes of pain through manual therapy, targeted exercises, and posture correction, often providing more lasting relief than medication alone.
4. Is it normal to have lower back pain every morning?
Recurring morning pain can indicate poor sleeping posture, an unsupportive mattress, or an underlying condition like disc degeneration. A physiotherapist can help identify the cause.
5. Should I rest or stay active with lower back pain?
Gentle activity is generally recommended over prolonged bed rest, as movement helps maintain flexibility and prevents muscle stiffness. However, activity should be modified to avoid aggravating the pain.
6. When should I be concerned about lower back pain?
Seek professional care if pain radiates down your legs, causes numbness or weakness, follows an injury, or persists for more than one to two weeks without improvement.
7. Can poor posture really cause chronic back pain?
Yes. Sustained poor posture places ongoing stress on spinal structures and muscles, which can lead to chronic pain if not corrected through ergonomic changes and strengthening exercises.
