Part 6 · Myth 28

Back pain is purely a mechanical, physical problem

Busted
From the Clinic

He'd had six scans, four courses of physiotherapy, and two epidural injections. Nothing explained his pain clearly. He was convinced something was being missed — there had to be a structural cause everyone had overlooked. He was frustrated, understandably. But more scanning wasn't the answer.

What Patients Say

My back has been scanned, examined, and nothing specific has been found. So my pain must be physical — there must be something structural that everyone keeps missing. Maybe I need more imaging?

Where Did This Come From?

This myth comes from a deeply understandable place: when you're in real pain and no one can find a clear structural cause, it's frustrating and frightening. The assumption is that if the pain is real, there must be something physically wrong that we just haven't found yet. The answer must be more scans, different scans, better clinicians.

This leads to what some call the "diagnostic odyssey" — a progression of imaging, referrals, and second opinions in search of a structural explanation for pain that is, at its core, not primarily structural. It can take years. And every negative result increases frustration and, paradoxically, often pain.

What the Science Actually Says

Back pain is a biopsychosocial phenomenon. The "bio" part — tissue damage, structural problems — is only one of three domains. The "psycho" part (psychology, beliefs, fear, mood) and the "social" part (work, relationships, cultural context) are equally real contributors to the experience of pain. This isn't alternative medicine or a way of dismissing your pain — it's the consensus of pain neuroscience.

Chronic pain can persist and be profoundly disabling without any ongoing tissue damage. The central nervous system becomes sensitised — the volume of pain processing is turned up, responding to stimuli that wouldn't normally cause pain, and amplifying signals from the body. This is a real, measurable neurobiological process. It's not "all in your head." But it does mean that more imaging of the back won't find the answer.

What does help for this type of pain? A combination of physical activity (graded, supported), psychological approaches (particularly cognitive behavioural therapy adapted for chronic pain, and pain education), sleep management, and addressing social factors. These are less tangible than a "fix" but they're what the evidence supports.

The Verdict

Chronic back pain without a clear structural cause is not pain that hasn't been properly diagnosed — it's a recognised biopsychosocial condition with real, evidence-based treatments. More imaging rarely helps.

Take-Home MessageYour pain is real. I want to say that clearly. But real pain doesn't always come from a findable structural problem, and pursuing more imaging in search of that problem can delay — and sometimes worsen — recovery. Ask your clinician about a pain management approach, not just a diagnosis hunt.

What To Do Instead

Yellow Flags — Worth Monitoring

  • New symptoms appearing in someone with chronic non-specific back pain — always warrant a fresh clinical assessment, even in someone with a long pain history
  • Depression, which is extremely common in chronic pain and requires its own targeted treatment

Red Flags — Get Checked Immediately

  • Chronic back pain with new constitutional symptoms (weight loss, fever, night sweats) — biopsychosocial pain does not cause these; exclude pathological cause
  • Chronic pain with new progressive neurological deficit
