Does Pain Always Mean Damage?A rule built on good evidence, and the pain it cannot account for

In the previous Insights article “What If My Chronic Pain Is Structural?” I ended on an unanswered question: what happens when the evidence begins to point toward neuroplastic symptoms, and that evidence runs against what you already believe about the cause of your pain?

The first thing to say is that the belief in question is very common. It is close to the most reasonable thing a person can believe about their own body, because it comes from direct experience.

It begins as an observation, repeated:

(1) I cut my finger.

(2) I feel pain.

(3) Therefore, pain means damage.

That is an induction, and a good one. The two things arrive together, every time – the first burn, the first scraped knee, the first time you came down badly on an ankle – and nothing in ordinary life contradicts it. Life experience taught you this before you could even speak, and by the time anyone described pain to you in words the generalization was already made.

What happens next is easy to miss. The generalization stops being a conclusion and becomes a premise – a belief now held rather than checked – and the reasoning runs in the other direction:

(1) Damage to my body causes pain (belief).

(2) I feel pain.

(3) Therefore, there is damage to my body.

The first premise is true. The second is true. But the conclusion does not follow. The structure has a name – affirming the consequent – and the reason it fails is that damage can produce pain, but pain also has other possible sources. In ordinary life that reversal is harmless, because it is nearly always right. But when it comes to neuroplastic pain the reversal does not correspond to how the pain is actually produced.

The rule

So we arrive at a rule: pain means damage. Once it is operative it works as a heuristic – a shortcut the mind applies without examining it, because examining it every time would be absurd. And it does real work. It is how the brain predicts what a sensation is about, and a large part of how we navigate the world without injuring ourselves.

What the rule is for

It is worth being clear that this is not merely a belief. It is a piece of training.

Take the example I used in “The Three Types of Pain”. I am cutting vegetables, the knife slips, and I cut my finger. Tissue is damaged, nerve endings signal it, pain arrives – and a programme runs immediately. I stop. I pull my hand back. I protect the finger and favour it, and I do not use it for the things I would ordinarily use it for. Then, over days, as the pain settles, I begin using my finger again.

That sequence was not a decision. It ran. And it is among the more successful things a body does. Stop, protect, wait, resume – it is why a sprained ankle heals rather than becoming a chronically re-injured ankle. For nociceptive pain, or standard pain, which reports genuine tissue trouble, the rule is not only true, but also useful. It protects us from injuring ourselves further.

So when I suggest that this belief may now be in your way, I also want to be clear about why it makes so much sense that it is. You have been running a rule that is correct, that was taught by experience rather than by anybody’s opinion, and that has served you well for most of your life.

How a good rule gets underneath

That success is exactly what makes it difficult.

A rule confirmed thousands of times without exception does not stay in the part of the mind where we weigh things. It sinks below that. The brain does not treat it as a syllogism. It just runs the programme. Expectation of this kind does not merely colour what you report about a sensation afterwards; it contributes to the perception of pain itself (Büchel et al., 2014).

Which means that when pain arrives you do not consult the rule. The rule has already run. The stopping, the guarding, the bracing, the not-using – all of it is underway before deliberation occurs. The programme is not a series of conclusions you have reached. It is the output of a well-trained system doing what it was trained to do.

When the rule meets a pain it was not built for

Now put that system in front of neuroplastic pain.

The signal is real. There is felt pain. But this pain is not reporting tissue damage. Yet, the programme runs anyway, as it has countless times before. Stop. Protect. Do not use it. Wait.

And here it does not merely fail to help. It feeds the thing it is trying to solve. Each act of guarding tells the threat appraisal system that its reading was correct. Avoidance narrows what you do, which narrows what the nervous system has evidence of as safe, which raises the alarm on whatever is left. The fear that follows is the appropriate response to a signal you have every reason to read as damage. This loop has been described in the pain literature for twenty-five years as the fear-avoidance model, and the prospective work is consistent with it: people who score high on fear of movement and re-injury after an episode of back pain are considerably more likely to still be disabled by it months later (Vlaeyen & Linton, 2000; Picavet et al., 2002).

So the rule that healed your ankle maintains your symptom. Not because you applied it badly, but because you applied it faithfully to something it was never about.

The hammer and the screwdriver

Here is how I tend to put it.

Standard pain is a nail, and the rule you were trained in is a hammer. It is a good hammer. It has driven a great many nails and it will drive more, because you have not stopped having nails – tissue still gets damaged and still needs protecting.

Neuroplastic pain is a screw. You can swing the hammer at a screw with real conviction. You can even swing harder when the screw does not go in like a nail. You can conclude that you have not swung hard enough and then keep using the same tool even though it does not work.

The neuroplastic model is not the claim that your hammer is useless. Rather, it is suggesting laying down the hammer in this context and picking up a different tool.

What actually changes

Less than you might expect, and nothing dramatic.

It does not mean overriding the pain, or pushing through it, or treating the signal as false. That is the hammer again, swung in the opposite direction.

What changes is that a step gets inserted before the programme runs. Ahead of the stopping and the protecting there is now a question: what kind of pain is this? What tool do I need? Sometimes the answer is that it is standard pain and the old programme is exactly right. Sometimes it is neuroplastic, or partly so – and then the response inverts. Where the hammer says withdraw, the screwdriver says approach. Move. Attend to the sensation with curiosity rather than alarm, and let the nervous system gather evidence that the activity is safe after all.

That is what somatic tracking is for, and it is why the Fs – fear, fighting against, fixing, focusing on, frustration, figuring out – are worth knowing by name. They are the hammer, reaching for a screw.

Where this leaves us

The belief ‘pain = tissue damage’ is not foolish. It refers to something true. You learned it the way everybody learns it, and you applied it consistently with good results.

However, the rule was handed to you without an exception clause. Nobody mentioned that there is a kind of pain the rule does not describe, or how to tell the difference, or what to do instead.

This article is one such exception clause. There are still nails that will need the right tool – a hammer rather than a screwdriver. But there are also screws that need a screwdriver and not a hammer. Knowing that you have more than one tool, and learning how to apply them to the correct objects, can make all the difference.
