Do I Really Need a Scan?

You’ve tweaked your back, rolled your ankle, or your shoulder’s been sore for weeks – and your first thought might be, “I should probably get a scan.” It’s totally understandable. When something hurts, it’s natural to want answers – and fast. But here’s the thing: scans aren’t always the best first step.

In fact, many people are surprised to learn that most musculoskeletal pain (like back, neck, or joint pain) can be safely assessed and treated without imaging. A physiotherapist is trained to figure out what’s going on through a detailed assessment – listening to your story, testing your movement, and checking specific muscles and joints.

So, when is a scan helpful? There are definitely times when it’s needed – like after a major injury (a fall, car accident, or sporting tackle), when there’s severe swelling or deformity, or if your physio suspects a fracture or serious tissue tear. Scans can also be useful if your symptoms aren’t improving after a reasonable period of rehab or if there are “red flags” suggesting something more complex (like nerve compression).

But in most everyday pain cases – like low back pain, knee soreness, or shoulder stiffness – scans often show things that sound worrying but aren’t actually the cause of your pain. For example, research shows that more than half of people over 40 have some “disc bulges” or “degeneration” on scans – even if they have no pain at all! [1] The same goes for “torn” tendons and “wear and tear” changes. They’re a normal part of ageing, not necessarily a problem that needs fixing.

The real value comes from getting a proper movement assessment first. A physio can determine what’s driving your symptoms – tight muscles, joint stiffness, weakness, poor movement patterns – and help you fix those causes directly. Often, people improve faster with targeted exercises and hands-on treatment than they would just by relying on imaging.

Think of it like this: a scan shows a snapshot, but your physio looks at the whole movie. They see how your body moves, how it compensates, and how it can recover – not just what a single image reveals.

If you’ve been putting off treatment because you think you need a scan first, here’s the good news: you probably don’t. Seeing a physio early means you can get answers, reassurance, and a clear plan to get back to doing what you love – without unnecessary tests or long waits.

So if you’re wondering, “Do I need a scan for this?” – come in and ask us. We’ll assess your condition, let you know if imaging is actually needed, and get you started on the right path to recovery.
