Chronic Back Pain: What Drives It & What Helps

Your back has been hurting for months. Not the sharp, dramatic kind that sends you to A&E — the slow, grinding kind that sits behind every decision you make during the day. Whether to pick up your child. Whether to take the stairs. Whether to cancel dinner because sitting in a restaurant chair for an hour sounds unbearable.

You have probably Googled it. You may have seen a GP who prescribed painkillers and told you to rest. The painkillers helped for a while. The rest made it worse.

Now you are somewhere between 'this is just my life now' and 'maybe I should see someone — but who?'

That uncertainty is not a personal failing. It is what happens when chronic pain does not come with a clear referral path.

What counts as chronic back pain

Back pain is considered chronic when it persists for more than three months. That is the clinical line. But the lived experience is different — it is the point where pain stops being an event and starts being a background condition that shapes how you move, work, sleep and think.

Acute vs. subacute vs. chronic

• Acute back pain — arrives suddenly, often after injury or awkward movement. Typically resolves within six weeks.
• Subacute back pain — the grey zone between six and twelve weeks.
• Chronic back pain — everything beyond twelve weeks. Behaves differently from the acute version in ways that matter for treatment.

Why chronic pain is not just 'acute pain that stayed'

When pain persists beyond a few months, the nervous system itself changes. Pain signals amplify. The brain becomes more sensitive to input from the back, even when no new tissue damage is occurring.

This is called central sensitisation and it means that a scan showing a disc bulge does not necessarily explain why you are still hurting. Disc bulges are common in people with zero pain.

How common is it in Singapore?

A 2022 cross-sectional study of 1,941 adults in Singapore's Central region found:

• 8.1% of the adult population reported chronic low back pain
• 80.5% of those had sought treatment — at a GP, specialist outpatient clinic or TCM practitioner
• Roughly 1 in 5 people living with chronic back pain had not sought treatment at all

Types of chronic back pain

Not all chronic back pain behaves the same way. Recognising the pattern helps you describe it accurately when you see a specialist.

By location

• Lower back (lumbar): By far the most common; bears the greatest load during sitting, standing and lifting
• Mid-back (thoracic): Less common, can relate to postural strain or thoracic spine conditions
• Upper back and neck (cervical): Often linked to desk work, screen use and muscle tension
• Sacroiliac joints: Pain near the pelvis, sometimes mistaken for hip or lower back pain

By mechanism

• Axial pain stays localised. A deep ache in one area that does not travel.
• Radicular pain follows a nerve path. Shooting or electric sensations down the leg (sciatica is the classic example).
• Referred pain is felt in the back but originates elsewhere — kidneys, pelvic organs or abdominal structures.

By underlying cause

• Non-specific; No single structural finding fully explains the pain. This is the majority of chronic cases.
• Structural; Herniated disc, spinal stenosis, degenerative disc disease, facet joint arthritis, spondylolisthesis.
• Inflammatory; Conditions like ankylosing spondylitis.
• Neuropathic; Driven by nerve damage or dysfunction.

The label 'non-specific' can feel dismissive. It is not. It simply means the pain is real but does not map neatly to one scan finding which is actually the norm for chronic back pain.

Symptoms beyond 'my back hurts'

Physical symptoms

• Deep, dull or burning ache in the back
• Stiffness and reduced range of motion
• Numbness, tingling or pins-and-needles travelling into the legs
• Sharp or shooting pain with certain movements

Functional symptoms most pages skip

• Sleep disruption: Not just from pain, but from the inability to find a comfortable position
• Positional intolerance: Reduced ability to sit or stand in one position, reshaping the workday
• Social withdrawal: Pulling back from exercise, hobbies and outings that used to define your week
• Reduced capacity for daily tasks: Bending, lifting, dressing, carrying groceries

A Singapore study of adults with chronic low back pain found they had poorer physical function, more difficulty with major life tasks and social activities, more depressive symptoms, and lower health‑related quality of life than those without pain — even after accounting for age, other conditions and lifestyle factors.

The psychological dimension

The same study found chronic low back pain was independently associated with:

• Higher depressive symptom scores
• Lower health-related quality of life
• Both findings held even after adjusting for comorbidities and demographics

Mood changes, irritability, a creeping sense that things will not improve — these are features of chronic pain, not separate problems.

What causes chronic back pain — and what keeps it going

The causes are layered. Treating only one layer often falls short.

Structural causes

These are the findings that show up on imaging:

• Degenerative disc disease
• Herniated (slipped) discs
• Facet joint osteoarthritis
• Spinal stenosis (narrowing of the spinal canal)
• Spondylolisthesis (vertebral slippage)
• Unresolved muscle or ligament strains

MRI studies of adults with no back pain at all routinely find disc bulges, degeneration and other 'abnormalities'. A structural finding on a scan does not automatically mean that finding is causing your pain.

Lifestyle and occupational risk factors

• Prolonged sitting is common in Singapore's office-dominant workforce
• Physical inactivity and deconditioning
• Excess body weight
• Smoking which reduces blood flow to spinal discs
• Poor workplace ergonomics
• Repetitive heavy lifting

The factors that predict whether pain becomes chronic

This is the gap in most patient education content. Research consistently identifies psychosocial factors as strong predictors of chronicity:

• Fear-avoidance behaviour: Avoiding movement because you fear it will worsen the pain. This leads to deconditioning, which makes the pain worse. A self-feeding cycle.
• Catastrophising; Magnifying the threat of pain and feeling helpless against it.
• Poor sleep, job dissatisfaction, high stress, low mood: All independently associated with chronic pain persistence.

These are not 'it is all in your head' factors. They are clinically recognised drivers. The Singapore data confirms it: the link between chronic low back pain and depressive symptoms held firm after adjusting for everything else.

How chronic back pain is diagnosed

The standard assessment

Diagnosis typically starts with:

• Clinical history: Location, duration, character of pain, aggravating and relieving factors
• Physical examination: Range of motion, neurological screening, specific provocation tests
• Red flag screening: Checking for symptoms that suggest serious underlying pathology

Imaging and tests

• X-ray checks for fractures or bony changes
• MRI assesses discs, nerves, infections, tumours
• CT scan shows greater bony detail than X-ray
• Nerve conduction study / EMG is used when nerve involvement is suspected

Imaging is primarily used to rule out serious pathology — infection, cancer, fractures, cauda equina syndrome. For most people with chronic back pain, the scan does not produce a single, neat explanation. That is normal and does not mean nothing can be done.

The Singapore care pathway

The typical pathway begins with your GP or polyclinic, who may manage initial treatment and refer you to a physiotherapist, orthopaedic surgeon or pain specialist depending on your presentation.

Treatments for chronic back pain

No single treatment resolves chronic back pain on its own. Current evidence supports a multimodal approach — combining several strategies — and starting conservative before escalating.

Self-management and staying active

This is the most evidence-backed first step, and the most underexplained on clinic websites.

A systematic review of 63 randomised controlled trials found that exercise had moderate evidence of benefit, with a number needed to treat (NNT) of 7. That makes exercise the strongest-performing intervention in the review.

Effective exercise approaches include:

• Aerobic exercise such as walking, swimming, cycling
• Core and back strengthening
• Flexibility and stretching programmes
• Yoga and clinical Pilates
• Aquatic therapy

Beyond exercise:

• Maintaining a healthy weight
• Ergonomic workspace setup
• Good sleep habits
• Pain neuroscience education — understanding how chronic pain works reduces fear, increases movement and improves outcomes

The key is consistency rather than intensity and choosing something you will actually do.

Physiotherapy and manual therapy

• Supervised programmes: Typically combine traction, heat therapy and progressive exercise to rebuild spinal muscle strength
• Manual therapy: Spinal mobilisation, soft tissue work, trigger point therapy, dry needling
• Postural correction: Ergonomic education to reduce daily mechanical load
• Return-to-activity guidance: Structured support for resuming activities you have been avoiding

The return-to-activity pathway matters as much as the hands-on treatment.

Psychological and mind-body approaches

Given the evidence linking chronic back pain to depressive symptoms and fear-avoidance, psychological approaches are treatment — not optional extras.

• Cognitive behavioural therapy (CBT) for chronic pain has a strong evidence base and helps shift thought patterns that amplify pain and avoidance.
• Mindfulness-based stress reduction is clinically supported for chronic pain management.
• Acceptance and commitment therapy focuses on living fully alongside pain rather than waiting for its elimination.

If you notice mood changes, withdrawal or feelings of hopelessness alongside your pain, mention this to your doctor. These symptoms are treatable, and addressing them frequently improves the pain itself.

Medication

Over-the-counter options:

• Paracetamol has limited evidence for chronic back pain
• Oral NSAIDs have moderate evidence of benefit

Prescription options for neuropathic pain:

• Tricyclic antidepressants
• Anticonvulsants (e.g. gabapentin, pregabalin)
• SNRIs (e.g. duloxetine) have moderate evidence
• Cox-2 inhibitors are used for inflammatory conditions where stomach safety is a concern
• Muscle relaxants are generally for short-term use only

What current guidelines do not recommend for most chronic back pain: long-term opioid use. The evidence is poor and the harm profile is significant.

Any decisions about medication should be made with your doctor or specialist, who can assess your specific situation.

Interventional treatments

When conservative approaches have not provided sufficient relief:

• Epidural steroid injections — corticosteroid and anaesthetic to reduce inflammation around compressed nerves
• Nerve blocks — target specific nerves, serve both diagnostic and therapeutic purposes
• Radiofrequency ablation — uses heat to interrupt pain signal transmission from facet joints, typically for degenerative joint-related pain

Some interventional procedures may be claimable through MediSave, depending on the diagnosis and procedure type.

Surgery

Surgery is not a first-line treatment. It is appropriate for specific structural pathologies that have not responded to conservative management — particularly with progressive neurological deficit, cauda equina syndrome or structural instability.

Common procedures:

• Discectomy for removal of herniated disc material
• Laminectomy for widening of the spinal canal
• Spinal fusion
• Disc replacement
• Spinal cord stimulation is a medical treatment using an implantable device that uses electrical signals to interrupt pain transmission, for refractory cases

Complementary and traditional approaches

The Singapore data shows that TCM clinics are part of the real treatment-seeking landscape. Acupuncture, tuina and chiropractic care are commonly used alongside conventional treatments.

Discuss these with your treating doctor to ensure they are coordinated with your overall management plan.

How chronic back pain reshapes daily life

Most information pages describe chronic back pain as though it is only about the back. It is not.

The study measured the impact across four domains and found significant impairment in every one — independent of other health conditions:

• Physical function: Difficulty with stairs, walking, bending, household tasks
• Social participation: Reduced engagement in community activities, exercise and leisure
• Work productivity: Chronic back pain is one of the leading causes of lost work days in Singapore
• Mental health: Depressive symptoms measurably higher, even after adjusting for age, sex, employment, lifestyle and number of other conditions

If this sounds familiar, these are documented, measurable effects of the condition — not signs that you are coping badly.

Preventing chronic back pain

Prevention is not about protecting your back from ever being hurt. It is about building a body — and a set of habits — that can absorb daily stresses without tipping into chronic pain.

• Regular physical activity for at least 150 minutes of moderate-intensity exercise per week
• Core strengthening to build muscular scaffolding around the spine
• Ergonomic workspace adjustments to reduce mechanical toll of long sitting hours
• Proper lifting mechanics, bending at the knees, not the waist
• Maintaining a healthy weight
• Not smoking
• Managing stress and sleep
• Addressing acute episodes early, before the psychosocial factors that drive chronicity have time to take hold

When to see a doctor

Red flag symptoms to seek urgent medical attention

• Loss of bladder or bowel control
• Progressive weakness or numbness in both legs
• Back pain with unexplained fever or weight loss
• Pain after significant trauma
• Known history of cancer with new-onset back pain
• Pain that consistently wakes you from sleep

These are not common, but they signal conditions that need rapid investigation.

When it is time for specialist input

• Pain persisting beyond four to six weeks despite self-management
• Pain significantly limiting daily activities or work
• Pain radiating below the knee
• Worsening numbness or tingling
• Mood changes, social withdrawal or hopelessness alongside physical symptoms — raise this with your doctor. It is part of the condition and it is treatable.

If you recognise yourself in this description, it is a reasonable point to seek answers rather than keep guessing whether it is “just muscular”, a disc problem or something else.
