One of the most upsetting things you can hear when you are living with persistent pain is:
“We can’t find anything wrong.”
For some people, those words come after months or even years of appointments, scans, blood tests, referrals and specialist consultations.
And instead of feeling reassured, you may feel more confused.
Because you are still in pain. You can feel it. It affects your sleep, your work, your relationships, your concentration and what you are able to do. So, if nobody can find a clear explanation, you may start asking yourself: “Why does it still hurt?”
Or perhaps even:
“Does this mean they don’t believe me?”
The first thing I want to say is this:
Pain can be completely real even when a scan or test does not provide a neat explanation for it. That is not unusual. And it certainly does not mean that the pain is “all in your head.”
Pain is real, even when the tests are reassuring
We often grow up with a very simple understanding of pain. Something is damaged. The damaged area sends a pain signal to the brain. The amount of pain tells us how much damage there is. That model works reasonably well in some situations. If you break a bone, cut your hand or sprain your ankle, pain is a useful warning system.
But persistent pain is often more complicated.
The relationship between tissue damage and pain is not always straightforward.
Some people can have quite significant changes on scans and experience relatively little pain. Others can experience severe pain even when scans show very little that would explain the intensity of their symptoms. This can feel baffling. But it begins to make more sense when we understand that pain is not simply a readout of tissue damage.
Pain is a protective experience created by the brain and nervous system.
Your nervous system is trying to protect you
In my pain psychology clinics both online and in person in Milton Keynes, I explain that the brain is constantly receiving information from the body. But it does not simply accept that information at face value. It interprets it. It asks, in effect:
“How much danger is there here?”
And that judgement is influenced by much more than the physical state of the tissues.
The nervous system also takes account of things such as:
- previous pain experiences
- stress
- poor sleep
- fear
- anxiety
- attention
- memories
- expectations
- how safe or unsafe you feel
- what you believe a sensation might mean
If the brain concludes that greater protection is needed, the pain experience may become stronger.
This is one reason pain can continue even after an injury has healed, or when tests do not reveal ongoing tissue damage that would fully explain the symptoms.
Think of an over-sensitive alarm system
I sometimes use the example of a home alarm. A good alarm system is designed to protect you. If someone breaks a window in the middle of the night, you want the alarm to go off.
But imagine that over time the system becomes extremely sensitive.
Now it goes off when a delivery van passes the house. It goes off when the wind moves a branch. It goes off when a cat walks across the garden.
There is still an alarm. The alarm is genuinely sounding. But it is no longer an accurate measure of how much danger is actually present.
Something similar can happen within the pain system. The nervous system can become sensitized.
It may begin responding strongly to signals that would previously have been interpreted as relatively safe. Pain is still real. But the system has become overprotective.
“So are you saying the pain is psychological?”
No. And I think this is an important distinction. Pain always involves the brain.
That is true whether you have broken your leg, have arthritis, have migraine, have back pain or are experiencing persistent pain that has no obvious explanation on imaging.
We cannot experience pain without a nervous system. So talking about the role of the brain does not mean saying the pain is imaginary. It means understanding the biology of pain more fully.
Psychological factors can also influence pain, but that does not make the pain psychological in the sense people often fear.
Stress can increase pain. Poor sleep can increase pain. Fear can increase pain. Attention can increase pain.
Feeling safe can sometimes reduce pain. Distraction can sometimes reduce pain. Enjoyment can sometimes reduce pain.
None of this means you invented the pain. It means that the pain system is responsive to context.
Why can pain continue after healing?
Imagine you injured your back several months ago. Initially, the pain encouraged you to protect yourself. You stopped bending. You moved cautiously. You avoided lifting. You became frightened of certain movements.
Perhaps every time you bent forwards, you anticipated pain. Your muscles tightened. You watched closely for symptoms and your brain learned:
“Bending is dangerous.”
Even after the tissues have healed, that learned protective response can sometimes remain.
The nervous system becomes very good at producing pain when you bend. Not because you are deliberately doing it. Not because the pain is imagined, but because your nervous system has learned to associate that movement with threat. The encouraging part is that the nervous system can also learn something new.
Why reassurance from a scan may not be enough
People are sometimes told:
“Your scan is normal, so there’s nothing to worry about.”
Medically, that may be reassuring. Emotionally, it can feel anything but reassuring. Because the person is thinking: “But I’m still in pain.”
A scan tells us about certain physical structures. It does not measure the sensitivity of the nervous system. It does not show fear. It does not show how much attention the brain is giving to a sensation. It does not show learned associations between movement and pain. It does not measure how safe your nervous system feels.
So, a reassuring scan and genuine pain can exist at exactly the same time. They are not contradictions.
Sometimes the search for an explanation becomes part of the problem
When nobody has been able to explain your pain, it is completely understandable that you keep searching. You may see another specialist. Request another test. Read about symptoms online. Compare your experience with other people’s. Check your body repeatedly. Try different movements to see whether the pain is still there. Ask yourself: What have they missed?
This search usually comes from a very understandable need for certainty. But there can be an unintended consequence. Every time you check the pain, your attention returns to it. Every frightening explanation increases the sense of threat. Every search can reinforce the message: “Something dangerous must still be happening.” And because the nervous system responds to perceived threat, this can sometimes keep the alarm system switched on.
This does not mean you should ignore new symptoms or avoid appropriate medical assessment.
It means that once serious causes have been investigated, there can come a point where continuing to search for damage is less helpful than learning how to calm and retrain the pain system.
What can I do if nobody can find a clear cause?
The first step is not to tell yourself: “There’s nothing wrong with me.” A more useful message may be: “My pain is real, but it may not be telling me that my body is being damaged.”
That distinction matters.
From there, we can begin working with the nervous system rather than constantly fighting the pain.
That may involve gradually returning to movements you have been avoiding. Reducing fear around normal bodily sensations. Improving sleep. Managing stress differently. Reducing repeated symptom checking. Learning relaxation or hypnosis. Using approaches such as cognitive behavioural therapy, Acceptance and Commitment Therapy, or pain reprocessing approaches. Building confidence in your body again.
And perhaps most importantly, slowly returning your attention to your life rather than asking your pain to give you permission to live it.
Becoming curious rather than frightened
If you notice a familiar pain sensation, your automatic response may be: “What’s wrong?”
You might experiment with another question: “What is my nervous system protecting me from right now?”
Perhaps you are tired. Perhaps you are stressed. Perhaps you have been frightened by this particular movement before. Perhaps your body is tense. Perhaps you have spent the last hour monitoring the sensation. Perhaps there really has been a temporary increase in symptoms.
Curiosity does not mean dismissing pain. It simply creates a little space between sensation and catastrophe.
Instead of: Pain = something is wrong
we begin moving towards:
Pain = my nervous system believes I need protecting. Let me understand why.
That can be a very powerful change.
You don’t have to prove your pain
Something else I wish more people with persistent pain were told is this: You do not need an abnormal scan for your pain to be legitimate. You do not need to convince everyone how much you hurt. You do not need a visible injury before you are allowed to struggle.
And you do not need to choose between: “My pain is physical” and “My pain involves my nervous system.”
Both can be true. Pain is biological, Psychological, Social, Contextual, Protective and deeply personal.
Understanding all of those dimensions does not minimize your pain. It gives us more ways to help.
The absence of damage can actually be hopeful
When tests show that there is no serious ongoing damage, it can initially feel frustrating.
But over time, that information can become reassuring.
Because if the pain system has become overly protective, then the goal is not necessarily to repair something that is continually breaking.
It may be to help the nervous system become less protective. To rebuild trust. To move with more confidence. To reduce fear. To create more experiences of safety.
And to teach the brain:
“This sensation is uncomfortable, but I am not in danger.”
That learning tends to happen gradually. It comes through experience. Through movement.
Through understanding. Through doing things that matter. Through discovering that your body can be capable even when it sometimes hurts.
Your pain is real. But it may not mean what you fear it means.
If you have spent months being told that your tests are normal while still experiencing significant pain, it is understandable to feel confused or dismissed.
But perhaps there is another way of looking at it.
Instead of: “Nobody can find what’s wrong with me.” we might begin with:
“They haven’t found ongoing damage that explains my pain. So perhaps I need to understand my pain system differently.”
That small shift can open up a very different path.
A path away from endlessly searching for the one missing abnormality and towards understanding, confidence, safety and gradually getting more of your life back.
Because pain is real.
But persistent pain does not always mean persistent damage.
And when we understand that distinction, we can begin asking a much more hopeful question:
“If my nervous system has learned to protect me this strongly, what can I do to help it learn that I am safe again?”
