Myofascial pain: the knots are real, but the alarm is what keeps them firing.
Tight bands, tender points, pain that spreads when pressed. Muscles that have been told, for months, to stay on guard.
Myofascial pain syndrome is pain in the muscles and the fascia, the sheet of connective tissue that wraps them, often concentrated in the chest, upper back and low back but able to appear almost anywhere. Its signature is the trigger point: a tender knot in a tight band of muscle that hurts when pressed and sends pain to a wider area. The ATNS Index of Neuroplastic Symptoms states that when myofascial pain is chronic, it is often neuroplastic. Neuroplastic symptoms are real pain produced by a sensitized brain and nervous system rather than by damage in the muscle, which is why rubbing, needling and stretching the knots so often brings relief that does not last. Research now links trigger points directly to central sensitization, and there is an approach that addresses the brain's role.
This page is about understanding the condition and the role the brain and nervous system can play in it. It is not a diagnosis. Your own clinicians know your case.
What myofascial pain syndrome is
Muscles are wrapped and threaded through with fascia, a tough connective tissue that holds everything in place. Myofascial pain syndrome is pain arising from this muscle-and-fascia system. The index describes it as existing throughout the body with an emphasis on the thoracic region (the chest and upper back) and the lumbar region (the low back). The classic finding is the trigger point: press on a specific spot in a taut band of muscle and you get a sharp local pain, often a twitch, and a referred ache somewhere else, such as a point between the shoulder blades that sends pain up into the head.
The condition becomes a syndrome when it persists for months, spreads, and resists treatment. At that point massage, dry needling, injections, stretching and heat may all help for a day or a week, and then the knots return.
The neuroplastic contribution
The ATNS Index of Neuroplastic Symptoms is brief and direct on this row: myofascial pain is often neuroplastic when chronic.
Neuroplastic symptoms are real symptoms produced by learned pathways in the brain and nervous system rather than by ongoing damage or disease in the body. They are not imaginary, not a weakness, and they can be unlearned. Muscle is the body's most responsive tissue to the state of the nervous system. When the brain perceives threat, whether from danger, stress, unexpressed emotion or fear of pain itself, it tightens muscles to brace. Held long enough, that bracing produces exactly the taut bands and tender points of myofascial pain. The trigger point is real tissue tension; what keeps it there is the signal from above telling the muscle not to let go.
Then the loop closes. Persistent input from tight, tender muscle sensitizes the spinal cord and brain, so lighter and lighter pressure hurts, pain spreads to neighbouring areas, and the brain becomes more vigilant about the body, which produces more bracing. This is why local treatments give temporary relief: they interrupt the muscle side of the loop but not the nervous system side.
What the research shows
The connection between trigger points and central sensitization has been studied for years. In an experimental study in healthy volunteers, researchers applied sustained painful pressure to a latent trigger point, one that is tender but not spontaneously painful, and showed that this input alone induced central sensitization, with increased pain sensitivity spreading beyond the stimulated area. A trigger point, in other words, can switch on the nervous system's amplifier even in a healthy person.
A historical and scientific review of myofascial trigger points traces how understanding has shifted from a purely muscular lesion to a phenomenon involving the nervous system, with central sensitization proposed as a primary mechanism in trigger point development, and summarises evidence that treating trigger points can reduce sensitivity at distant sites, at least temporarily.
A 2026 integrative review proposes a stress-fascia-pain axis for myofascial pain syndrome. It describes central sensitization as a process that can arise from persistent peripheral input and then contribute to spread, recurrence and a symptom burden out of proportion to any tissue finding, and argues that the syndrome cannot be fully explained by either a purely structural or a purely central model. That is the index's position in research language: the muscle and the nervous system are both involved, and when the pain is chronic, the nervous system is in charge. For more on the mechanism, see why chronic pain persists; for the closely related whole-body picture, see fibromyalgia.
Signs the brain may be part of the picture
- Pain has lasted months, spread, or shifted from one region to another.
- Massage, needling, injections or stretching help for a short time, then the knots return.
- Pain flares with stress, conflict, deadlines, poor sleep or suppressed anger.
- You hold tension habitually: clenched jaw, raised shoulders, braced stomach.
- Scans and blood tests are normal, or show only age-typical findings.
- You have other sensitized-system symptoms: headaches, IBS, fatigue, TMJ pain, pelvic pain.
Find the brace and let it go
Set a timer for three minutes and sit or lie down. Scan slowly from your jaw to your feet, pausing at each area you tend to hold: jaw, tongue, shoulders, chest, belly, buttocks, hands. At each one, ask whether it is braced, and if it is, let it soften by about half, not all the way. Then find your most tender trigger point and, instead of pressing it, simply rest your attention there and describe the sensation in neutral words: tight, warm, a dense spot. Ask yourself what the muscle might be guarding against, and let whatever answer comes sit for a moment. Finish with three slow out-breaths.
A solution that addresses it
There is an approach that addresses the brain's contribution to muscle pain. Pain and symptom reprocessing begins with education about neuroplastic symptoms, then builds skills: somatic tracking (observing the tight, aching sensation with curiosity instead of bracing against it), reducing the sense of threat, a graded return to full movement, emotional awareness and expression (particularly useful here, since muscle tension so often carries unexpressed feeling), and acceptance and commitment skills (ACT). Trained clinicians deliver it, and digital programs are making it widely available.

What to do next
First, see a clinician to make sure nothing else is going on. Chest and back muscle pain can occasionally mimic or hide heart, lung, spine or inflammatory problems, so get prompt assessment for chest pain with breathlessness, sweating or pain spreading to the arm or jaw, for pain with fever or weight loss, or for new weakness or numbness.
Second, if the examination and tests are reassuring and the pain has been going on for months, ask whether your symptoms fit a neuroplastic pattern.
Third, start learning and practising. Keep moving, following a paced approach rather than resting or pushing, and begin a daily practice that works on the nervous system's hold on your muscles. Flares will happen; see them as the old bracing habit, not fresh injury.
Questions people ask
Is myofascial pain syndrome a neuroplastic condition?
When it is chronic, often yes. The ATNS Index of Neuroplastic Symptoms says chronic myofascial pain is often neuroplastic, meaning a sensitized brain and nervous system are keeping the muscles tense and tender. The pain is real and physical, and it can be unlearned.
Are trigger points real?
Yes. Taut bands and tender points in muscle can be felt and have been studied for decades. Research shows that pressing a trigger point can induce central sensitization, and that the nervous system is a key part of why they form, spread and recur.
Why does massage or dry needling only help for a few days?
Local treatments relieve the muscle side of the loop but not the nervous system that is instructing the muscle to brace. Unless the brain's sense of threat is addressed, the tension returns. That is why approaches that calm the nervous system tend to produce more lasting change.
