One of the most frustrating things about chronic symptoms is that sometimes they make absolutely no sense.
Your back hurts every time you sit at your desk, but somehow you sat through an entire movie last weekend without thinking about it. You can eat a certain food one day and feel completely fine, then eat the exact same thing three days later and have symptoms for hours. Your pain starts in your neck, moves into your shoulder, disappears for a few months, and then shows up somewhere else entirely.Or maybe you’ve had test after test, tried treatment after treatment, and still don’t have a satisfying explanation for why you feel the way you do. It’s easy to look at all of that inconsistency and think, My body is completely unpredictable.
I know that feeling very well. During my own years of chronic pain and other symptoms, there was always something to analyze. A symptom would change, a new one would appear, something that hurt yesterday would mysteriously be fine today, and I would try to figure out what I had done differently. I became extremely good at collecting evidence for the case that something was wrong with my body. What took me much longer to realize was that some of the things that made the least sense were actually useful information.
Because sometimes the question isn’t, Why is my body so unpredictable?
It’s: What does this pattern tell me?
Neuroplastic symptoms are real symptoms
First, a quick definition, because I think this is where people understandably get nervous.
Neuroplastic symptoms are real physical symptoms that are created or amplified when the brain and nervous system respond to safe signals as if they are dangerous. That can include chronic pain, but the nervous system can also be involved in things like dizziness, headaches, digestive symptoms, fatigue, muscle tension, and other persistent physical sensations.
The word neuroplastic refers to the brain’s ability to learn and change. Most of the time, we’re pretty grateful for that ability. It’s how you learned to drive a car without consciously thinking, Okay, right foot on the brake. Check the mirror. Turn the wheel. Eventually, your brain learned the pattern and started doing most of it automatically.
Unfortunately, the brain can also learn patterns we don’t particularly want it to learn.
Sitting can become associated with back pain. Eating can become associated with stomach symptoms. Exercise can become associated with fatigue. A particular movement can become associated with danger. A certain time of day, place, position, or sensation can start predicting what happens next. Eventually, the response can happen so automatically that it feels like something that simply happens to you. And in a way, it does. You are not consciously creating the symptom. Your brain has learned a response. The much harder question is whether that’s actually what is happening for you. I wish there were one blood test, scan, or very official-looking machine that could give us a nice clean answer. There isn’t. Instead, I think of this as detective work.
I’m less interested in one clue than I am in the whole pattern
One of the first things I pay attention to is inconsistency.
Maybe sitting usually hurts, but occasionally it doesn’t. Maybe walking around the grocery store for twenty minutes is miserable, but you spent an hour walking somewhere you love and realized afterward that you were fine. Maybe mornings are normally awful, except for that random Tuesday when you woke up and felt surprisingly good. When this happens, people are very good at dismissing the exception. I just got lucky. It was a good day. I probably did something differently. Maybe. But I’m interested in the exception.
If the same body can do the same activity without producing the expected symptom, I want to know why. That doesn’t prove the symptom is neuroplastic. But it tells us the response is capable of changing, and that matters. I pay attention to symptoms that move, spread, change sides, disappear, return, or seem to break their own rules too. Bodies are complicated, so I’m not going to tell you that pain moving from your back to your hip automatically means it’s neuroplastic. But when symptoms repeatedly behave in ways that are difficult to explain structurally, I don’t want to ignore that either.
The same is true of context. Maybe your back hurts terribly in your office chair but somehow tolerates an airplane seat on the way to vacation. Maybe your stomach becomes unpredictable before leaving the house but settles once you’re somewhere you feel comfortable. Maybe your dizziness ramps up the second you walk into a grocery store but is much less noticeable outside. Those differences are interesting to me because pain and other symptoms don’t happen in a vacuum. The brain is always taking in context—where you are, what you expect, what has happened there before, how safe or threatened you feel, and what it thinks needs your attention.
Sometimes people hear that and immediately say, “But I wasn’t stressed when this started.” That may be completely true. I don’t think every symptom needs a hidden emotional explanation, and I’m not interested in making “stress” into an answer that can never be wrong. If you feel stressed, that’s why you hurt. If you don’t feel stressed, apparently you’re repressing it. Convenient theory. What I care about is whether there is a pattern.
Did symptoms begin during a period of illness, loss, uncertainty, fear, pressure, or physical stress? Do they flare when your nervous system is under more strain? Do they ease when you’re distracted, engaged, laughing, traveling, or doing something that feels safe? Do they predictably show up in certain situations that your brain may have learned to associate with danger?
One clue by itself may mean very little. Several clues together can start to tell a story.
Sometimes the trigger looks guilty because it keeps showing up at the scene
This is one of the hardest parts. A symptom appears every time you do something, and naturally you think, Well, obviously that thing is causing it.
Your headache starts every afternoon around 3:00. Your stomach hurts before you leave the house. Your back starts hurting within minutes of sitting in a certain chair. Symptoms appear when you drive, exercise, eat a particular food, lie down to sleep, or even think about doing the thing that has caused symptoms before. Understandably, the trigger looks guilty. Sometimes it is. But sometimes predictability itself is part of the clue.
Brains learn associations. If something has repeatedly happened alongside pain or another frightening sensation, the brain can begin anticipating danger when it encounters that situation again. Eventually, the expectation can become part of the response. Attention can work similarly. Maybe you’re having symptoms and then a friend calls. One of your kids needs you. You get absorbed in a project. You start watching a movie that completely pulls you in. An hour later, you realize, Wait. Where did the pain go? And almost on cue, you check for it. There it is.
That does not mean you imagined it the first time. Attention can influence how strongly the brain processes physical sensations. If a symptom changes substantially depending on what you’re doing, where your attention is, or how threatened you feel, I consider that another useful piece of the larger picture. Not proof. A clue.
An injury or medical finding doesn’t automatically rule neuroplasticity out
This is another place where people often get stuck. “But mine started after an injury.”
Okay. That matters.
Sometimes there really was an injury, illness, surgery, infection, or other physical event. Your brain had a perfectly good reason to protect you. But sometimes the body heals and the protection sticks around. That doesn’t mean the original injury wasn’t real. It means the nervous system may still be responding based on what it learned during that period.
Medical findings can be complicated too. Sometimes tests come back normal even though the symptoms are anything but mild. Other times something does show up on an MRI or another test, but it still doesn’t explain the whole story. Maybe the finding doesn’t match the severity of symptoms, maybe the symptoms are more widespread than the finding would suggest, or maybe treatment aimed directly at the suspected structural problem didn’t change much.
I’m not looking for a reason to dismiss medical findings. I want the explanation to make sense of the whole story. That’s an important difference.
This is why I love an Evidence List
When you’ve had symptoms for months or years, your brain becomes an excellent lawyer for the case that something is wrong. It has receipts. Every flare. Every bad day. Every painful movement. Every time you tried something and regretted it. Meanwhile, the evidence on the other side tends to disappear pretty quickly. That random pain-free afternoon? Probably meaningless. The walk you thought would hurt but didn’t? Just a good day. The symptom that disappeared while you were on vacation? Interesting, but then it came back, so apparently it didn’t count. Except maybe it did.
Because sometimes those experiences tell us something important about what our bodies are capable of. If you walked farther than you thought you could, moved in a way you normally avoid, or spent an afternoon doing something you love without the symptoms you expected, that’s worth paying attention to. It doesn’t automatically mean there’s nothing physically wrong. But it may suggest that your body has more capacity than your symptoms have led you to believe, and that the nervous system’s protective response isn’t as fixed as it feels.
This is why I often use an Evidence List with clients. We write down the experiences that may point toward the brain and nervous system playing a role: inconsistencies, symptom-free experiences, things your body unexpectedly tolerated, changes with attention or context, learned triggers, symptoms moving around, or anything else that doesn’t fit neatly into a purely structural explanation.
We are not trying to talk you into believing something that isn’t true. We’re making sure both sides get to present their case.
And sometimes this is where the picture starts becoming much more personal than an online checklist can capture. One person’s most compelling clue may be that pain disappears every time they travel. Someone else has a symptom that predictably switches sides. Another person has been told their MRI explains everything, but the actual symptom pattern doesn’t line up very well with the finding. Someone else has no dramatic inconsistency at all, but when we talk through the timeline, we realize the symptoms began in a very specific context and have followed learned triggers ever since.
That’s why I don’t love reducing neuroplastic symptoms to “If you have three of these seven signs, congratulations, it’s your nervous system.”
Real people are messier than that.
What if I’m still not sure?
You might not be. That’s okay.
You do not need 100% certainty before you can begin considering whether neuroplasticity may be part of what’s happening. And at the same time, PRT is not about deciding that every unexplained symptom must be neuroplastic. New, concerning, or unexplained symptoms deserve appropriate medical evaluation, and medical conditions that need treatment should be treated.
Sometimes it isn’t either/or, either. A person can have a real structural or medical issue and a nervous system that has become sensitized and is amplifying the symptoms associated with it. So instead of only asking, Is this physical or neuroplastic?, I think the more useful question is: What does the whole pattern tell me? That’s the question I usually want to explore with someone.
Not just what hurts, but when it started. What makes it better. What makes it worse. What you’ve been told. What you’re afraid it means. What your body has done that surprised you. Which pieces fit the medical explanation you’ve been given—and which pieces stubbornly refuse to. Sometimes the pattern becomes surprisingly clear once we put it all on the table. And sometimes it doesn’t. Both are useful.
Want to look at your own symptoms?
If you were mentally checking boxes while reading this, I created a free Neuroplastic Symptoms Self-Assessment to help you look more closely at some of these patterns in your own experience. It isn’t a diagnosis, and no questionnaire can tell you with certainty what is causing a symptom. But it can help you start gathering your own evidence.
And if you’re wondering what we actually do once we believe symptoms may be neuroplastic, you can read What Is Pain Reprocessing Therapy (PRT)? next.
Want to talk it through?
I also offer free 15-minute connect calls where we can talk a little about your symptoms, what you’ve already tried, and whether PRT and working together might make sense for you.
