Chronic Back Pain
Chronic low back pain is one of the most common reasons patients seek medical attention and one of the leading causes of missed work and lost function worldwide. Despite how prevalent it is, it remains one of the most poorly managed conditions in medicine — not because the treatments do not exist, but because the diagnostic discipline required to apply them correctly is inconsistently practiced. Most patients with chronic low back pain have never had a structural diagnosis established. They have had imaging, they have had medications, and they have had physical therapy directed at their symptoms rather than their pain generator. Understanding what chronic low back pain actually is — and what it is not — is the starting point for managing it effectively.
THE BASICS
What Chronic Low Back Pain Is and Where It Comes From
Chronic low back pain is defined as pain persisting for more than twelve weeks. Unlike acute pain, which is a reliable signal of recent tissue injury, chronic pain is a more complex phenomenon that reflects not only the ongoing activity of peripheral pain generators but the neurological changes that develop when pain signals are sustained over time. The brain interprets and modulates pain — it does not simply receive it passively — and the experience of chronic pain is shaped by sleep quality, psychological state, prior pain experiences, and the degree of central sensitization that has developed. This does not mean that chronic low back pain is imaginary or that its structural contributors are irrelevant. It means that treating the MRI finding without treating the person who carries it produces predictably incomplete results.
The structural pain generators most commonly responsible for chronic low back pain include facet joint arthritis and capsular inflammation, intervertebral disc degeneration and annular disruption, sacroiliac joint dysfunction, and nerve root irritation from foraminal stenosis or disc herniation. Poor posture, movement dysfunction, and muscle deconditioning do not generate pain independently but create the mechanical environment in which these structural problems develop and persist. Old injuries that were never fully rehabilitated, asymmetric loading patterns from occupation or sport, and the progressive loss of the core stabilization that supports spinal mechanics all contribute to the clinical picture in ways that imaging alone cannot capture.
CLINICAL EVIDENCE
A Comprehensive Approach — What the Evidence Supports
The evidence for managing chronic low back pain consistently points toward a multimodal strategy that addresses the structural, neurological, and functional dimensions of the problem simultaneously. Movement is among the most important interventions available — not as a generic recommendation but as a specific prescription. Avoidance of movement in chronic low back pain consistently worsens outcomes by accelerating deconditioning, increasing central sensitization, and reinforcing the fear-avoidance cycle that perpetuates disability. Structured physical therapy addressing movement quality, core stabilization, hip mechanics, and postural control provides the functional foundation on which all other treatments build. Osteopathic manipulative medicine complements physical therapy by addressing soft tissue restriction, joint mobility, and segmental dysfunction that impaired movement perpetuates — using the diagnostic information from the hands-on examination to direct treatment with a specificity that exercise programming alone cannot provide.
Targeted interventional procedures — medial branch blocks and radiofrequency ablation for facetogenic pain, transforaminal epidural injections for radicular components, sacroiliac joint blocks and lateral branch ablation for SI-mediated pain, and intradiscal procedures for discogenic pain — address confirmed structural pain generators with a precision that oral medications cannot replicate. The critical principle is that these procedures follow from a diagnosis rather than preceding one — the intervention is selected because the pain generator has been identified, not because the symptom location suggests a target. Regenerative medicine with intradiscal PRP and BMAC provides a biologic option for disc-mediated pain in patients where the degenerative process is the primary driver and conventional injections have provided insufficient or short-lived relief. Mind-body optimization — addressing sleep quality, anxiety, depression, and the central sensitization that chronic pain both produces and is sustained by — is not supplementary to the treatment plan. For many patients it is the variable that determines whether every other intervention works or fails, and it deserves the same clinical attention as the structural diagnosis.
PATIENT SELECTION
What the Evaluation Looks Like in Practice
Every patient I evaluate for chronic low back pain receives a comprehensive history that characterizes the pain — its quality, its behavior with different positions and activities, its response to prior treatments, and the functional limitations it imposes. The physical examination tests the integrity of specific structures, identifies movement dysfunction, and generates a differential diagnosis grounded in anatomy. Imaging is reviewed in the context of the clinical picture rather than used to drive it — the most common error in spine care is treating the MRI rather than the patient, and avoiding that error requires an examination that can distinguish which of the findings on imaging are clinically relevant and which are incidental. When the clinical picture warrants it, targeted diagnostic blocks confirm the pain generator with a precision that neither imaging nor physical examination can achieve independently. From that diagnostic foundation, a treatment plan is built around the patient's specific pain generator, functional goals, and medical context — not around a protocol applied to a symptom category.
FOR REFERRING CLINICIANS
Patients with chronic low back pain who have not had a comprehensive diagnostic evaluation — who have been managed on the basis of imaging findings or symptom location rather than a confirmed pain generator — represent the most important referral opportunity in spine medicine. I offer the full diagnostic and treatment pathway for chronic low back pain, from structural evaluation and targeted diagnostic blocks through the complete range of conservative, interventional, regenerative, and surgical coordination services. The goal of every evaluation is a diagnosis, and every treatment recommendation follows from that diagnosis. I welcome direct physician-to-physician consultation.
PERSPECTIVE
A Note on Treating the Person, Not the Scan
The single most common mistake I see in the management of chronic low back pain is the conflation of imaging findings with clinical diagnosis. An MRI that shows disc degeneration at L4-5 does not tell you that disc degeneration at L4-5 is responsible for the patient's pain — it tells you that disc degeneration is present. Establishing which structure is generating the pain, and why, requires clinical reasoning, physical examination, and in many cases targeted diagnostic procedures that the standard care pathway for chronic low back pain never reaches. The patients who arrive at my practice after years of inadequate treatment are not rare. They are common, and the gap between what they have received and what was available to them represents one of the most significant failures of musculoskeletal medicine at scale. Chronic low back pain is not a mystery. It is a collection of distinct, diagnosable, treatable conditions that share a symptom location and have been collapsed into a single category that medicine has treated as though the category were the diagnosis. Reversing that — establishing what is actually wrong and treating it with the precision the problem deserves — is what this practice is built to do.
