Diagnosis Series Ep. 3: The 6 Most Common Causes of Lower Back Pain
Welcome to the first episode in my Diagnosis Series, where I dive deep into the real-world causes of lower back pain—the most common complaint in musculoskeletal practice.
In this episode, we’ll explore the six most common mechanical lower back pain diagnoses that I see regularly in clinical work. The goal is to simplify complex presentations and help both patients and clinicians think more clearly when trying to understand why back pain happens.
🔍 Topics covered include:
✅ The importance of ruling out red flags first
✅ Why most cases of LBP are not from a single source
✅ How lifestyle, injury, and systemic factors combine
✅ Core diagnostic categories and their typical signs
You’ll learn how to recognise these 6 major causes of lower back pain:
Disc herniation/discogenic pain – leg symptoms, stiffness, trouble sitting
Facet joint syndrome – pain with twisting, transitional movements
Muscle or ligament strain/sprain – overstretch, fatigue, or faulty movement
Spondylosis – degenerative arthritis of the spine with reduced mobility
Sacroiliac joint dysfunction – sharp pain, instability, often on one side
Hypermobility/spinal instability – ligament laxity, poor joint control
We also touch on how these categories often overlap in practice, and why diagnostic clarity helps guide smarter treatment—not just symptom chasing.
📌 You’ll also hear about:
Red flags to rule out (e.g. cauda equina, fracture, infection, cancer)
Why most pain is mechanical, not pathological
The difference between structural findings and clinical symptoms
How psychosocial, metabolic, and environmental factors contribute
Bonus movement tips for managing symptoms safely at home
🧠 Whether you’re a manual therapist (osteopath, physio, chiro), a student, or a person struggling with recurring back pain, this episode is designed to help you understand why pain occurs—not just what to do about it.
While we won’t go deep into treatments here, I do give some early movement advice, symptom clues, and frameworks to start narrowing your differentials. Full diagnostic testing and rehab strategy will follow in future episodes.
🎧 Make sure to listen to my episode on “How I Diagnose” first if you haven’t already—it gives crucial context to how I think through complex cases.
