Ask a physiotherapist: should you avoid movements that hurt?

I stub my toe fairly regularly. And every time, the pain is immediate and intense, radiating up through my whole body before fading almost as quickly as it came. I have got pretty good at riding that wave.

My back pain is a different story. When it flares, I do not ride the wave. I brace against it. I find myself quietly adjusting how I sit, how I get out of bed, how I reach for things, building a whole library of small workarounds to avoid the movements I know are going to set it off. It feels smart. It feels protective.

But after years of working with people in pain, I have seen what happens when avoidance becomes the default. And the research tells a more complicated story than our instincts do.

Why pain makes us want to stop

Pain evolved as a protective mechanism. When you break a bone or tear a muscle, your brain's response — stop, protect, do not use that part — makes complete biological sense. The pain signal is doing exactly what it is supposed to do: preventing further damage to tissue that genuinely needs rest.

The problem is that the brain is not always precise about which situations call for that response. It learns patterns. If a movement has been associated with pain enough times, the brain can start generating a pain signal in anticipation of injury rather than in response to it, even after the original tissue damage has healed. The signal feels just as real and just as urgent. But what it is telling you is no longer accurate.

This is not a character flaw or a sign of weakness. It is a well-documented feature of how the nervous system works, and it affects a significant number of people managing MSK conditions. The discomfort is real. What has changed is its source.

How avoidance makes the cycle worse

When we avoid movements that cause pain, we send the brain a clear message: this is dangerous. The more consistently we avoid something, the more convinced the brain becomes that the avoidance is necessary. Over time, the range of movements that feel safe shrinks. The threshold for triggering a pain response drops. What started as a reasonable response to an acute injury becomes a pattern that keeps you stuck.

Research on the fear-avoidance model of chronic pain shows that this cycle — pain, fear, avoidance, deconditioning, more pain — is one of the most common pathways through which acute MSK injuries become long-term problems.¹ The physical component compounds the original issue. A knee you have been guarding for months has less muscular support than it did before, which makes it genuinely more vulnerable, which gives the brain more reason to protect it. The cycle is self-reinforcing.

The good news is that it runs in both directions. The same plasticity that allowed the brain to learn avoidance can be used to unlearn it.

Understanding your pain first

None of this means you should push through everything. The first and most important step is understanding what is actually causing your pain — and that process is often less frightening than people expect.

The vast majority of MSK pain has a treatable mechanical or movement-related cause. My first job as a physiotherapist is to find the true source: whether the pain is coming from the structure you think it is, whether it is referring from somewhere else, and whether anything in the picture suggests a cause that needs a different kind of attention. Getting that clarity is not just practically useful. It changes how the pain feels. When you understand that your pain is not a sign of serious ongoing damage — that it is your nervous system doing its protective job a little too aggressively — part of the fear that has been amplifying it starts to ease.

That shift in understanding has measurable effects. Pain science education, delivered alongside physiotherapy, has demonstrated meaningful reductions in pain levels, fear of movement, and disability in people with chronic MSK conditions.³ Knowing what is happening in your body changes your relationship to the signals your body sends.

The right kind of discomfort

Once you understand the source of your pain, the next step is learning to distinguish between types of discomfort. This is one of the more nuanced parts of recovery, and it is genuinely difficult to calibrate alone.

There is discomfort that is part of rebuilding. The mild ache of a muscle working harder than it has in a while. The temporary flare that sometimes follows a session of therapeutic exercise. The effort of moving into a range that has felt restricted for months. This kind of discomfort is expected in recovery, and working through it carefully is part of how strength and mobility are rebuilt. A systematic review and meta-analysis found that exercise involving some degree of pain produced outcomes comparable to pain-free exercise for people with chronic MSK conditions — meaning that avoiding all discomfort is not a requirement for effective recovery.⁴

Then there is discomfort that is a signal to pause: sharp pain, pain that radiates in a pattern suggesting nerve involvement, swelling that increases after a session, or pain that does not settle within 24 hours. These are worth flagging so your plan can be adjusted. The line between the two is not always obvious from the inside, which is precisely why having a physiotherapist read your responses and adapt accordingly makes such a difference.

Movement as medicine

There is a reason movement is the cornerstone of physiotherapy rather than rest. Exercise is consistently amongst the most effective treatments available for chronic MSK pain, with evidence across a wide range of conditions and delivery formats.² Physical inactivity, by contrast, is associated with worsening pain over time.²

Movement does several things simultaneously that medication alone cannot replicate. It strengthens the muscles that support an injured joint, reducing the load the joint itself has to carry. It promotes circulation to tissues that need it for healing. It desensitises nervous system pathways that have become hypervigilant, gradually rebuilding the brain's confidence that a movement is safe. And it activates your body's own pain-modulating capacity in ways that change how the nervous system processes the signals it receives.

People who stay active during recovery often report a better experience than those who rest — not just because their muscles are stronger, but because their nervous system is less sensitised to pain. Movement and pain relief are not opposites. For most MSK conditions, movement is the mechanism.

Why getting the prescription right matters

Knowing that movement helps is one thing. Knowing which movements, in what sequence, at what intensity, with what modifications for your specific anatomy and history is something else entirely. Getting that prescription wrong in either direction — too much too soon or too little for too long — can aggravate the injury or deepen the avoidance pattern further.

This is the gap that most people hit when they try to manage MSK pain on their own. Generic advice to 'stay active' or 'do some stretching' does not account for where the pain is coming from, what stage of recovery the tissue is at, or how much fear and avoidance has built up around certain movements. Without that specificity, well-intentioned effort can easily stall or backfire.

Structured physiotherapy is designed to fill exactly that gap. A physiotherapist builds a plan calibrated to where you are right now, monitors how you respond, and adjusts as you progress. They also address the psychological dimension of recovery — the fear, the unhelpful beliefs about what pain means, the catastrophising — because those factors have measurable effects on outcomes and cannot simply be exercised away.³

The bottom line

Avoiding movement when you are in pain feels like the right thing to do. For acute injuries in the short term, it sometimes is. But for most MSK pain, the longer avoidance continues, the harder recovery becomes. The same nervous system that learned to protect a painful joint can learn that movement is safe again — and physiotherapy is specifically built to guide that process.

Understanding what your pain is actually telling you — and learning to distinguish the discomfort of rebuilding from the signal to pause — is not something most people can calibrate reliably on their own. That clarity comes from having a physiotherapist assess the true source, explain the mechanism, and build a plan specific enough to take the guesswork out. Education and movement, combined, are consistently the most effective route through chronic MSK pain.²

The path out is not about pushing harder or resting more. It is about moving with the right information, in the right sequence, with someone adjusting the plan as you respond. That is what recovery looks like when it actually works.
