Understanding Pain Beyond Images
Pain is a brain‑generated experience that integrates past injuries, stress, sleep, beliefs and nervous‑system sensitivity, not merely tissue damage. Imaging modalities—X‑ray, MRI, CT—show bones, discs and joints but cannot reveal nervous‑system sensitization, muscle tension, fascial restrictions, central sensitization or psychosocial factors that drive pain. Because structural findings such as disc bulges or arthritis appear in up to 97 % of asymptomatic adults, they often do not explain symptoms. A holistic assessment that combines detailed history, movement testing, functional screening and patient‑reported outcomes provides the information needed to identify true pain generators and guide non‑invasive, movement‑focused care and improve long‑term function outcomes.
When Imaging Is Truly Needed
Red‑flag signs (severe or progressive neurologic deficits, bowel/bladder dysfunction, unexplained weight loss, fever, recent trauma, cancer history, infection, osteoporosis‑related fracture, cauda‑equina syndrome) trigger imaging. Guidelines from Choosing Wisely, AANS/ACEP, and the ACR advise against routine imaging for acute low back pain within the first six weeks unless such red flags appear. In those cases a plain‑film X‑ray is usually the first step to assess bony alignment or fracture; MRI is reserved for soft‑tissue, disc, or nerve‑root evaluation, and CT when detailed bone imaging is needed. For most patients (90‑95 % non‑specific) a trial of conservative, non‑invasive care—education, activity modification, physical therapy, chiropractic adjustments, myofascial release—should proceed for at least four to six weeks before any advanced imaging. MRI is ordered only after persistent symptoms despite appropriate treatment or when surgical planning is considered.
The Body’s Response to Unnecessary Scans
Repeated imaging—especially ion‑ modalities such as X‑rays and CT scans—delivers low‑dose radiation that accumulates over time. Even modest exposure is linked to DNA damage and a small increase in cancer risk, and high‑dose procedures can cause tissue inflammation or burns.
Incidental findings are common: studies show that up to 97 % of asymptomatic adults have disc bulges, meniscus tears or arthritis on MRI or X‑ray.
When these “abnormalities” are reported, patients often undergo additional tests or invasive procedures that carry infection, anesthesia, and scar‑tissue risks.
The psychological impact is significant.
Unexplained or alarming images trigger fear‑avoidance, heightened cortisol, and stress that can amplify pain perception and impair healing.
Does a CT with contrast hurt? The injection is usually painless; a brief sting or metallic taste may occur, but discomfort is minimal compared with diagnostic benefit.
Physiological effects of unnecessary imaging – cumulative radiation, tissue inflammation, and stress‑induced cortisol spikes can outweigh any marginal benefit.
What are the limitations of medical imaging? Imaging shows structure but not pain intensity, and it can produce false‑positives or false‑negatives.
Is it normal to have pain but MRI is normal? Yes; pain can stem from soft‑tissue strain, nerve irritation, or central sensitization that normal MRI findings cannot detect.
Pain Is More Than a Picture
Pain is generated by the brain, not simply by what an MRI shows. Psychogenic pain arises when stress, anxiety, or trauma cause the nervous system to interpret threat as discomfort, even without tissue injury. Myofascial pain syndrome is a chronic condition marked by taut muscle bands and trigger points that refer pain to distant sites; it is diagnosed clinically and treated with targeted myofascial release, adjustments, corrective exercises, adjunct modalities such as cold‑laser therapy.
Three core assessment methods guide care: self‑report scales (e.g., the Numeric Verbal Pain Scale, 0‑10), behavioral observation tools (e.g., the Behavioral Pain Scale for non‑verbal patients), and physiological measures (heart‑rate, blood pressure, or advanced imaging). These approaches capture the multidimensional nature of pain, allowing chiropractors to tailor non‑invasive, function‑focused treatment without over‑reliance on imaging findings.
When Scans Miss the Mark
Imaging modalities such as MRI, CT, and X‑ray provide structural information but do not show pain intensity, nervous system sensitivity, load tolerance, movement quality, or stress levels
Can inflammation be missed on MRI? Early or low‑grade inflammation may be subtle and escape routine MRI sequences; specialized techniques (STIR, fat‑suppressed T2, gadolinium‑enhanced scans) improve detection, yet no modality is foolproof.
Can MRI miss a torn meniscus? MRI is ~95 % sensitive, but small peripheral tears, atypical patterns, or scans only in sagittal view can be overlooked, especially in younger patients with vascular meniscal tissue.
Fibromyalgia is a central‑sensitization syndrome; structural scans are normal because the pain originates from altered brain‑spinal processing rather than visible tissue damage.
What happens if an MRI doesn’t show anything? A normal scan simply means no structural abnormality was seen. Pain may still arise from soft‑tissue strain, nerve irritation, or central sensitization, which are best addressed with hands‑on care—spinal adjustments, myofascial release, corrective exercises, and lifestyle education—rather than additional imaging.
Chiropractic Care in the Imaging Era
Medicare imaging rules – Chiropractors generally cannot order MRI for Medicare beneficiaries; a treating physician must place the order per CMS 42 CFR 410.32(a). Only a few demonstration states (Maine, New Mexico, parts of IL, IA, VA) allow limited chiropractor‑ordered CT/MRI with proper documentation.
Osteoporosis considerations – Patients with osteoporosis may safely receive chiropractic care when the practitioner uses low‑force techniques, avoids high‑velocity thrusts, and tailors treatment to bone‑density status. Open discussion of fractures, medication and density scores is essential.
Sciatica treatment – Chiropractic management targets nerve compression through gentle adjustments, spinal decompression, myofascial release and corrective exercise, often reducing pain without surgery.
FLACC vs CPOT – Use the FLACC scale for children or non‑intubated adults who cannot self‑report pain; the CPOT is designed for intubated, sedated ICU patients and incorporates muscle tension and ventilator compliance.
Putting It All Together: A Path to Relief
Comprehensive Assessment
A thorough history and physical exam reveal the true drivers of pain—movement quality, nervous‑system sensitization, muscular strength, and psychosocial stress—far beyond what MRI or X‑ray can show. Evidence shows that 30‑40 % of chronic low‑back sufferers have normal scans, while up to 97 % of asymptomatic adults display disc bulges or arthritis. Hence clinicians first triage for red‑flag signs and then use functional tests (range of motion, postural analysis, myofascial palpation) to pinpoint the pain source.
Non‑Invasive Therapies
Targeted chiropractic adjustments, myofascial release, spinal decompression, corrective exercises, and lifestyle coaching address load tolerance, muscle balance, and nervous‑system re‑training—factors imaging cannot measure. Randomized trials confirm that such approaches improve pain and function even when imaging remains unchanged.
Patient Education & Empowerment
Educating patients that pain is generated by the brain, not solely by structural damage, reduces fear‑avoidance and promotes active self‑management. Clear communication about the limited value of routine imaging, combined with a personalized functional plan, empowers individuals to regain confidence and achieve lasting relief.
A Way Forward
Empowering patients starts with clear education: explain that imaging often reveals age‑related changes that are not the pain source, and that the nervous system, movement quality, and lifestyle factors drive most discomfort. Offer a shared‑decision model where patients choose evidence‑based, non‑invasive options such as targeted chiropractic adjustments, myofascial release, corrective exercises, and pain‑neuroscience education. These therapies address load tolerance, nervous‑system sensitization, and functional confidence—factors imaging cannot measure—while avoiding unnecessary radiation, cost, and fear‑avoidance behaviors. By focusing on function and self‑management, clinicians help patients regain control and achieve lasting relief.
