MRI’s are an incredibly accurate way of imaging the back, giving us detailed anatomical information about the structures inside. However, we have since learnt that knowing what is inside doesn’t tell us the full story. In fact, for lower backs, it is often very normal for there to be findings on your scan that represent no threat and are not the cause of your pain.
Why MRI Scans Don’t Always Explain Back Pain
MRIs are highly accurate at showing the anatomy of your spine. They can reveal disc bulges, degeneration, or joint changes. But here’s the surprising fact:
Many of these findings are completely normal.
A disc bulge or degeneration may have been present long before your pain started.
These changes often remain even after your pain resolves—without ever causing symptoms.
In other words, an MRI finding doesn’t always mean it’s the cause of your back pain
What the Research Tells Us
Large studies looking at thousands of people with no history of back pain have found that so-called “abnormal” findings—such as disc bulges, disc degeneration, or joint changes—are incredibly common. This tells us that these changes are often a normal part of ageing, rather than a direct cause of pain.
So while an MRI can look alarming, your physiotherapist knows how to interpret these results in the context of your symptoms, lifestyle, and physical examination.
When an MRI Is Useful
Scans can still play an important role. Your physiotherapist may recommend imaging if they suspect something more serious, such as:
Fractures
Cancer
Infections
Severe nerve compression
In most cases of lower back pain, though, an MRI is not needed to guide your treatment. Instead, your history, physical assessment, and functional goals are far more useful in creating an effective rehab plan.
How Physiotherapy Helps With Back Pain
An experienced physiotherapist will:
Assess your movement, strength, and posture
Help you understand your pain and what’s causing it
Design a personalised rehab program to restore mobility and build strength
Provide hands-on treatment, education, and strategies to get you back to your normal activities safely
The focus is not just on short-term pain relief but also on long-term resilience—so you can reduce flare-ups and get back to doing what you love.
