Back pain is the single leading cause of disability in the UK, affecting approximately 2.5 million people every day. Despite its prevalence, it is frequently mismanaged — by both patients and healthcare systems. Understanding the evidence for what works — and what doesn’t — saves months of unnecessary suffering and inappropriate treatment.
Types and Causes of Back Pain
Non-specific low back pain (NSLBP) accounts for approximately 85% of back pain presentations. “Non-specific” means no identifiable structural cause is found — and this is normal. The back is a complex structure of bones, discs, joints, muscles, ligaments and nerves, and pain can arise from many sources without a single identifiable culprit. Provocative factors include poor posture, muscle deconditioning, sedentary behaviour, stress (which significantly amplifies pain perception), and biomechanical loading. Disc-related pain: intervertebral discs can bulge or herniate, sometimes compressing nerve roots (producing sciatica — pain, tingling or weakness radiating into the leg). Most disc herniations resolve spontaneously within 6–12 weeks. Spinal stenosis: narrowing of the spinal canal, most common in older adults, producing neurogenic claudication (leg symptoms worsening with walking and relieved by sitting). Other causes: fractures (especially in osteoporosis), inflammatory conditions (ankylosing spondylitis — morning stiffness, improves with movement, onset in young adults), and rarely, serious pathology.
Red Flags: When to Seek Urgent Assessment
The vast majority of back pain is benign and self-limiting. However, certain features require prompt medical assessment: new bladder or bowel dysfunction (cauda equina syndrome — emergency); progressive neurological weakness or numbness in the legs; saddle anaesthesia (numbness in the groin/inner thighs); severe pain that is constant and unrelenting, worse lying down and at night; fever with back pain; recent significant trauma; unexplained weight loss; back pain in anyone under 20 or over 55 presenting for the first time; history of cancer, immunosuppression, IV drug use, or prolonged corticosteroid use.
What the Evidence Shows Works
Staying active — the most evidence-backed intervention for acute non-specific back pain. Bed rest and avoidance of activity is actively harmful, prolonging recovery. Staying as active as pain allows, and returning to normal activity as quickly as possible, produces faster recovery than rest. Exercise — for chronic back pain, exercise is the most effective intervention overall (Cochrane review, 200+ RCTs). Yoga, Pilates, and specific back exercise programmes (McKenzie method) all have evidence. Core strengthening and general aerobic fitness reduce recurrence risk significantly. OTC analgesia: NSAIDs (ibuprofen, naproxen) have stronger evidence than paracetamol for acute back pain. Topical NSAIDs (Voltarol gel) are effective with minimal systemic absorption. Heat wraps have evidence for acute pain. Physiotherapy — particularly for chronic or recurrent back pain; manual therapy has short-term benefit. CBT and pain management programmes — for chronic back pain, psychological approaches addressing pain catastrophising and fear-avoidance are more effective long-term than physical treatments alone.
Frequently Asked Questions About Back Pain
Does my MRI showing a disc bulge explain my back pain?
Not necessarily. Studies imaging the spines of pain-free volunteers consistently find disc bulges, degeneration, and other structural changes in the majority — these are extremely common age-related findings rather than necessarily the cause of pain. Back pain and MRI findings often correlate poorly. This is why modern guidelines recommend against routine MRI for non-specific back pain — it frequently identifies “abnormalities” that aren’t causing symptoms, leading to anxiety and unnecessary interventions.
Should I use a back support belt?
For specific short-term use (manual handling during a flare), a support belt may reduce loading and pain. Long-term regular use is not recommended — it risks muscle deconditioning and dependency. Building core strength through exercise provides more sustainable support.
When is surgery appropriate for back pain?
Surgery is appropriate for: cauda equina syndrome (emergency); progressive neurological deficit from disc herniation unresponsive to 6 weeks of conservative treatment; spinal stenosis with significant functional limitation unresponsive to conservative management; structural instability. For non-specific low back pain, surgery is not appropriate — and multiple trials have found it no more effective than conservative management.
