Why Pain Can Outlast the Injury: What I’ve Learned Treating Chronic Pain
If you take only two things away from this post, let them be these:
Pain is not just a measure of tissue damage.
Pain isn’t the end point. It’s part of the body’s alarm system, which sets off a chain of responses. I call that response the body’s bubble wrapping.
Over the years, I’ve worked with a lot of people in pain.
Some have been dealing with it for weeks. Others have lived with it for years, sometimes decades. Many have already been through the usual list of treatments: physical therapy, medications, injections, imaging, and even surgery.
By the time they find their way into my office, some are frustrated, some are skeptical, and some have simply run out of options.
And then there are the patients who come back after treatment, look at me with a bewildered expression, and ask:
“What kind of voodoo magic did you just do?”
They’ve spent years trying to get relief, and perhaps accepted that the pain was just something they would have to live with. Then something changes.
It is not magic. But I understand why it can feel that way.
To understand why acupuncture can sometimes make a difference when other approaches haven’t, we first need to look at how we understand pain.
Pain isn’t always what we think it is
Pain is not simply a measurement of tissue damage. It is an output of the nervous system, influenced by sensory input, inflammation, previous experiences, and the body’s perception of threat.
This is one of the most important distinctions in understanding chronic pain.
We tend to think that if something hurts, something must still be damaged. And if the damage is repaired, the pain should go away.
But the body doesn’t always follow that logic.
I’ve seen patients who have healed from an injury, completed rehabilitation, regained strength, and still experience pain. Others have undergone surgery to correct a structural problem, only to find that the pain never completely disappeared.
How does that happen?
Because the tissue and the nervous system are not the same thing.
Pain isn’t a direct reading of what’s happening in the tissue. It’s the nervous system’s interpretation of information coming from the body. Pain tells us something about what the nervous system is experiencing, not necessarily how much damage exists.
Think of a smoke alarm that becomes overly sensitive.
Initially, it was installed to alert you to a real fire. But eventually, it starts going off when someone makes toast.
The alarm isn't necessarily broken. It's just set too sensitively.
Something similar can happen with chronic pain.
After an injury, the nervous system can turn up the sensitivity of the alarm for that area. Over time, it may begin sounding off in response to movements, pressure, or sensations that would not ordinarily be considered threatening.
The original injury may be resolved, but the alarm keeps ringing.
And when an alarm goes off, the body doesn't just sit there. It acts. Inflammation may develop around the injured area. Muscles contract to guard it. The surrounding fascia may become tighter, and gradually, we may even change the way we walk, move, and distribute our weight.
I think of this as the body's bubble wrapping. It's the body's way of protecting an area, limiting movement, and creating conditions for repair. In the short term, this makes sense. The body is essentially trying to wrap up and protect an area it perceives as vulnerable.
But if the alarm keeps ringing, the bubble wrap can stay on long after it's needed. What started as protection can eventually become part of the problem.
The pain is real. The experience is real. But the volume of that alarm may no longer reflect what's happening in the tissue itself.
This is why someone can spend years trying to fix the painful area without changing the pain. You can keep searching the room for flames, but if the fire is already out, the problem isn't necessarily the room. It's the alarm.
Where acupuncture comes in
When people think about acupuncture, they often think about needles increasing circulation, releasing tight muscles, or stimulating the body’s natural healing response.
Those are relevant parts of the picture.
Inserting a needle creates a controlled sensory stimulus. It activates nerve endings and sends information through the nervous system. Local blood flow and other physiological processes may also be affected.
But there’s another part of acupuncture that I find particularly interesting.
It’s not just the signal being sent. It’s the state of the system receiving that signal.
During acupuncture, many patients become deeply relaxed. Some fall asleep. That familiar acupuncture nap is something I see regularly in practice.
Acupuncture may influence autonomic activity, supporting the parasympathetic responses associated with rest and recovery.
And this is where the conversation becomes particularly interesting.
The brain doesn’t interpret sensory information in isolation.
Imagine catching the scent of someone you love.
Before you even consciously think about it, you may feel a sense of comfort, familiarity, or calm. The scent itself isn’t inherently relaxing. Your brain has associated that particular sensory experience with safety, affection, and positive memories.
The scent hasn’t changed. The context and meaning your brain associates with it have.
An alarm works the same way. The same sound means something very different at 3 a.m. than it does when you’re standing over the stove.
Our nervous system processes sensory information in a similar, context-dependent way. The brain considers incoming signals alongside previous experiences, emotional associations, and the body’s current physiological state.
Now consider someone who has lived with chronic pain for years.
Their alarm has been sounding for so long that even ordinary movement or touch can set it off.
During acupuncture, we approach this differently.
We first help the body settle into a calmer, more regulated state, supporting parasympathetic activity, often called the rest-and-digest response.
Then we introduce sensory input through the needles, including input from the area associated with pain.
The brain receives and processes that information in the context of the body’s current state.
Rather than setting off the same alarm again, we’re giving the nervous system an opportunity to experience input from that area under different conditions.
With repeated experiences, this may help change how the brain and nervous system process those signals, contributing to lower sensitivity and a quieter alarm.
We’re not simply trying to cut the wires or mute a pain signal. We’re giving the nervous system a different experience to learn from.
In a sense, we’re helping the brain recalibrate an alarm that has been set too sensitively for too long.
I don’t have a magic needle
Of course, not every patient walks out of the first treatment pain-free.
And I think it’s important to talk about that, too.
Sometimes someone comes into my office after living with pain for ten or twenty years, hoping that one acupuncture session will make it all disappear.
I wish I had a magic needle. I really do.
But when an alarm has been set to high sensitivity for years, we shouldn’t expect it to recalibrate overnight.
Some people notice a difference after their first treatment. Others need a series of treatments before they begin to notice meaningful changes.
Every person is different. The nature of the injury, the duration of the pain, the individual’s health, and many other factors matter.
The goal isn’t to promise that every person will become pain-free. It’s to help create conditions that may allow the nervous system to turn the volume down and the body to move toward better function and recovery.
Maybe we’ve been looking at only part of the problem
When someone has been in pain for years, it’s understandable that they focus on the place that hurts.
That’s where the attention goes. That’s where the treatments have been directed. That’s where everyone has been looking.
But pain is more complicated than a problem in one particular spot.
Sometimes the tissue needs attention. Sometimes the muscles need strengthening. Sometimes a structural problem needs to be corrected.
And sometimes, we need to look beyond all of that.
We need to consider the nervous system that has been interpreting those signals and sounding the alarm all along.
After all these years of treating pain, this is one of the things I find most important to help patients understand:
The goal isn’t always to keep treating the place that hurts. Sometimes it’s to help the nervous system recalibrate, so the alarm goes off only when there’s a real fire.
Sometimes the next step isn’t doing more to the injury. It’s changing the conversation between the body and the brain.
And that may be what finally turns the alarm down.
