What Your MRI Can and Cannot Tell You About Your Pain

You remember exactly where you were sitting when you got the results.

For some people, the news was heavy. Multi-level degenerative disc disease. A bulge at L4-L5. A tear in the meniscus. A partial thickness rotator cuff tear. Words that sounded like a verdict, delivered in the tone providers use when they are being careful with you. You left the appointment carrying a report that named things you had never heard of and could not stop thinking about.

For other people, the news was somehow worse. The imaging came back unremarkable. Age-appropriate. Nothing structural to explain what you have been feeling. You sat with that answer and wondered whether the pain you have been living with is not real, or whether something has been missed, or whether you have simply been assigned to the category of patients that medicine cannot fully account for.

Both of these experiences share something that most people are never told. The picture you were shown, and the story you were told about it, is describing structure. It is not describing pain. And the distance between those two things is larger than almost anyone realizes.

What the Research Actually Shows

Some of the most useful research on imaging comes from studies that scanned thousands of people who reported no pain at all and looked at what showed up anyway. The results are worth sitting with.

A systematic review published in the American Journal of Neuroradiology in 2015 pooled data from 33 studies and more than 3,000 asymptomatic adults. In people with no back pain of any kind, disc degeneration appeared on MRI in 37 percent of 20-year-olds and 96 percent of 80-year-olds. Disc bulges appeared in 30 percent of 20-year-olds and 84 percent of 80-year-olds. Disc protrusions, the finding many patients hear described as a herniation, showed up in 29 percent of 20-year-olds and 43 percent of 80-year-olds.

These are people who were not in pain. Their scans looked like the scans of patients who are told their pain is being caused by exactly these findings.

What this evidence has taught the research community is that many of the features that get flagged as pathology on imaging reports are, in a significant portion of the population, normal age-related changes. They coexist with pain in some people. They coexist with no pain at all in an enormous number of others. And the presence of a finding on a scan is not, by itself, an explanation for why a specific person is hurting.

What Imaging Does Well

This is not an argument against MRIs. Imaging is a genuinely important tool when it is used to answer the specific questions it is designed to answer.

MRI is excellent for identifying serious pathology that requires medical or surgical intervention. Fractures. Tumors. Infections. Severe nerve compression producing progressive weakness. Complete tears of tendons or ligaments that will not respond to conservative care. In these cases, imaging changes the treatment plan in ways that matter enormously, and the ability to see inside the body without opening it up is one of the more significant advances in modern medicine.

Imaging is also useful before certain surgical decisions, when a clinician needs to understand structural anatomy in order to plan a specific procedure. That is a specific question, and imaging answers it well.

Where imaging becomes less useful, and sometimes actively misleading, is when it is used to answer a question it was not designed for: what is causing this person’s pain, and what should be done about it.

Why Imaging Misleads in Both Directions

When findings appear on a scan, they get named. When they get named, they take on the weight of an explanation, even when the evidence for that explanation is weaker than the tone of the report suggests. This creates two very different problems depending on which side of the scan the patient is on.

For the patient whose MRI came back with findings, the results can produce a specific kind of harm that the research community has started calling nocebo effect. Being told that you have a bulging disc, degenerative changes, or a torn structure changes how you move. You start protecting the area. You avoid activities you associate with the finding. You interpret ordinary sensations as evidence that something is getting worse. Studies have shown that patients who receive detailed imaging reports about degenerative findings, without context about how common those findings are in pain-free people, tend to have worse outcomes and more disability than patients whose reports include that context. The finding was already there before the scan. What changed was how the patient understood their own body afterward.

For the patient whose MRI came back clean, the problem is different but equally real. The absence of a structural finding gets interpreted as an absence of a mechanical explanation. If nothing is wrong on the scan, the reasoning goes, then the pain must be functional, stress-related, or otherwise not addressable through physical means. That reasoning misses that a large portion of chronic pain is produced by movement patterns, load distribution issues, muscle imbalances, and nervous system sensitivity that imaging cannot show. A clean MRI does not mean nothing is wrong. It means nothing structural is wrong. Those are different statements.

In both cases, the scan gave an accurate picture of anatomy and an incomplete picture of the problem. The gap between what the scan can see and what is producing the pain is where most patients get stuck.

What Actually Predicts Recovery

If imaging findings do not reliably predict who is in pain or who will get better, what does?

The strongest predictors of pain outcomes are functional, not structural. How well the person moves. Where load is being shared or hoarded across the body. Where one area is compensating for another and why. How well the tissue tolerates being asked to do more over time. How the nervous system responds when certain movements come up, whether it stays calm or braces against them. And how sleep, stress, and overall capacity are either supporting the body or working against it.

These are the variables that determine whether someone with a bulging disc has debilitating pain or none at all. They are also what determine whether someone with a clean MRI recovers quickly or spends years in chronic pain. And crucially, they are the variables that respond to intervention. Structure changes slowly, over years. Movement, load distribution, and nervous system tolerance can shift meaningfully in weeks with the right work.

This is why a movement assessment is often more useful than an imaging report for determining what to do about chronic pain. The scan describes what you look like inside on a specific day. The assessment describes how your body actually functions under the demands of daily life. The second picture is closer to what is producing the symptoms, and closer to what can be changed.

When Imaging Is Genuinely Useful

There are situations where imaging should absolutely be part of the picture, and where getting it earlier rather than later is the right call.

• Progressive neurological symptoms, including new weakness, numbness that is spreading, or loss of bowel or bladder control
• Symptoms following a specific traumatic event, particularly a fall, motor vehicle accident, or sports injury with a clear mechanism
• Pain that is not responding to appropriate conservative care over a reasonable period of time
•  Symptoms that are getting worse despite treatment rather than gradually improving
•  Pain accompanied by systemic signs like unexplained weight loss, fever, or night sweats
• Pre-surgical planning where the clinician needs specific structural information to make a treatment decision

In these situations, imaging is not overused. It is doing the job it was designed for. The question of overuse comes up in a different situation: when imaging is ordered as the first step for a new episode of pain, before a clinical assessment has been done, and before any conservative care has been attempted. In that scenario, findings often appear that would have been there before the pain started, get interpreted as the cause of the pain, and set the treatment plan in a direction that may not match what is actually driving the symptoms.

How to Read Your Own MRI Report More Accurately

If you already have an imaging report and you are trying to understand what it means, a few things are worth knowing.

Words like degeneration, bulge, protrusion, wear, and tear appear on a large portion of reports in asymptomatic populations. The presence of these terms in your report does not, by itself, tell you whether they are contributing to your pain. Their significance depends on where they are, what other findings are present, and how they correlate with your specific symptoms and clinical presentation. That correlation is a job for a clinician who is examining you, not for the report itself to determine.

The words on the report are also written in a technical vocabulary that tends to sound more severe than it clinically is. Radiologists are trained to describe every finding they see, which is exactly what they should do. But that thoroughness produces reports that can read alarmingly to a patient who has no reference for how common these findings are. Reading your report next to the statistics from the research above tends to reframe the tone considerably.

If a specific finding on your report has been named as the cause of your pain and the treatment has not worked, it is worth considering whether the finding is actually the driver, or whether it happens to coexist with a movement or load-distribution issue that is doing the real work. The answer often becomes clear only through a careful clinical examination, not through the imaging itself.

What Comes Next

If you have been given a diagnosis based on an MRI and the treatment has not resolved your symptoms, or if your MRI has come back clean and you have been told there is nothing to address, an assessment focused on how your body actually moves and loads is often the missing piece.

The scan describes anatomy. The assessment describes function. What produces most chronic pain, and what changes it, lives in the second picture. Understanding that distinction does not mean the scan was wrong or unnecessary. It means the scan was answering one question, and the question your body has been asking all along is a different one.

At DPT, a movement assessment looks at how load is being distributed, where capacity is falling short, and what movement patterns are contributing to your symptoms. It is the piece that typically has not been done for patients who have been through imaging without clear answers. A discovery visit is a practical way to talk through what you have been experiencing and determine whether a movement-based evaluation is worth pursuing next.
