Hurt vs. Harm: Why Pain Doesn't Always Mean Damage

By Dr. Michael Minenna D.C., B.Sc., SFMA, FMS

It's one of the most natural assumptions in the world: if something hurts, something must be damaged, and the more it hurts, the worse the damage. It feels obviously true. It's also one of the most consistently overturned ideas in modern pain science — and understanding why can genuinely change how you recover from an injury.

Pain is an output, not a sensor

We tend to picture pain like a smoke detector wired directly to the tissues: damage triggers a signal, the signal travels to the brain, you feel pain in exact proportion. Decades of research have shown the reality is far more interesting. Pain is produced by the brain based on its best judgement of whether you're in danger — drawing on signals from the body, yes, but also on context, beliefs, stress, sleep, mood, and past experience.^1,2 It's a protective output, not a precise damage readout.

This is why the relationship between pain and tissue damage is so loose in both directions. People can have significant tissue changes — disc bulges, meniscus tears, rotator cuff changes — visible on imaging with no pain at all. And people can have severe, very real pain with no detectable damage. The pain is never "imaginary" in either case; it's just that pain and damage are two different things.

Hurt is not the same as harm

This distinction matters enormously in recovery. "Hurt" means a tissue or your nervous system is sounding an alarm. "Harm" means actual damage is occurring. They often coincide — but frequently they don't, especially with persistent or recurring pain. A back that hurts when you bend isn't necessarily being damaged when you bend; often it's a sensitized, over-protective system reacting to a movement it has come to associate with threat.²

When we treat all hurt as harm, we tend to do the things that make pain worse over time: we stop moving, we guard, we brace, we avoid. That protective behaviour is wise in the short term after a genuine injury, but when it persists it leads to deconditioning, fear, and a nervous system that stays on high alert — which can keep pain going long after any tissue has healed.

Why this is good news

The reframe is empowering rather than dismissive. If your pain doesn't automatically equal ongoing damage, then movement isn't something to fear — it's part of the path back. Understanding pain in this way is itself part of the treatment: when people learn how pain actually works, their pain and disability often decrease.¹ Knowledge, in this case, is a real intervention.

It also fits how we approach rehab. There are no bad exercises, only too much too soon. We don't avoid movements because they're "dangerous"; we dose them to the level your system can handle and build from there, helping a sensitized nervous system relearn that movement is safe.

What this looks like in practice

Best-practice care for most musculoskeletal pain leads with exactly this: education, reassurance, and a graded return to activity, rather than rest and fear.³ We help you understand what's going on, distinguish the hurt that's worth respecting from the harm that genuinely needs caution, and rebuild confidence and capacity step by step.

None of this means ignoring pain or pushing recklessly through it — some pain genuinely signals harm, and part of a good assessment is telling the difference. But for the large majority of everyday aches and persistent pains, the most useful thing to know is this: hurting does not mean you're harming yourself. At Boreal Spine & Sport, that understanding is often where real recovery begins.
