You have had that knot worked on before. Maybe many times. The massage therapist found it, dug into it, and it released. You left feeling better. And then, two weeks later, it was back. Same spot. Same depth. Same ache radiating up your neck or down into your hip.
This is one of the most common frustrations I see in people who arrive at the practice after years of managing their pain rather than resolving it. The treatment worked. The tissue released. But the knot came back because nothing changed about the conditions that produced it.
Understanding why that happens requires understanding what a trigger point actually is, not just as a sore spot but as a biological event with a specific mechanism.
What a Trigger Point Actually Is
The term gets used loosely. People call any tender area a knot, and the word has become so general it has almost lost clinical meaning. A true myofascial trigger point is something more specific: a hypersensitive nodule within a taut band of skeletal muscle that produces predictable referred pain, local twitch response, and measurable changes in the chemical environment of the surrounding tissue.
The foundational model comes from Janet Travell and David Simons, whose research across the latter half of the twentieth century produced the most comprehensive mapping of trigger point behavior in the literature. Their integrated hypothesis, formalized in the second edition of Myofascial Pain and Dysfunction: The Trigger Point Manual (1999), described a cycle driven by abnormal acetylcholine release at the motor endplate. When a muscle fiber is overloaded, the neuromuscular junction can release excessive acetylcholine, causing sustained sarcomere shortening in the immediate area. The fiber cannot fully relax. Local circulation is impaired. Energy demand increases. The result is a local energy crisis — a small region of tissue caught in a loop of contraction it cannot exit without intervention.
That model held up well, and it was substantially deepened by NIH researcher Jay Shah. Shah and his colleagues used in vivo microdialysis, a technique that samples the chemical environment of living tissue in real time, to compare what is actually present at active trigger points versus latent ones versus healthy muscle. What they found was striking. Active trigger points are bathed in a measurably different chemical milieu: elevated concentrations of substance P, calcitonin gene-related peptide (CGRP), bradykinin, tumor necrosis factor-alpha, and interleukin-1 beta, all of them sensitizing agents (Shah & Gilliams, Journal of Bodywork and Movement Therapies, 2008).
This is not a minor chemical variation. It is a local inflammatory environment that keeps nociceptors sensitized, sustains the pain signal, and makes the surrounding tissue hypersensitive to pressure. It also helps explain why active trigger points hurt more, refer pain further, and are harder to treat than latent ones. The tissue chemistry is genuinely different.
What Trigger Point Therapy Does at the Tissue Level
Trigger point therapy is designed to interrupt that cycle. The techniques vary: sustained manual compression, ischemic pressure, dry needling, strumming across the taut band. But the mechanism of effect is consistent across approaches. Applied pressure temporarily increases local ischemia, which appears to flush the chemical milieu when circulation returns. The twitch response often observable during treatment is thought to represent a brief spinal reflex arc, with the taut band releasing as the sarcomere contraction breaks. Post-treatment, local blood flow increases, sensitizing agents are cleared, and the tissue returns toward a more normal resting state.
The effect is real. Anyone who has had skilled trigger point work done has felt it. The tissue softens. The referral pattern quiets. The range of motion that was limited a moment before comes back.
The problem is not whether trigger point therapy works. It does. The problem is what it does not address.
Why the Knot Comes Back
Trigger points are not random. They form in muscles that are under load they cannot manage: too much load, load applied in positions of weakness, or load distributed unevenly because some muscles are pulling duties that others have stopped doing.
In clients with chronic low back or neck pain, the pattern is nearly universal: the deep stabilizing muscles (the lumbar extensors, the multifidus, the cervical extensors) are inhibited and weak. They have been underloaded for years, often since an original injury. When those muscles are not doing their job, the surrounding musculature compensates. Superficial muscles take on work they were not built to sustain. They shorten, brace, and over time develop the very trigger points that send the client into a treatment cycle.
Release the trigger point, and the muscle can relax. But the structural load is still present. The deep stabilizers are still inhibited. The compensation pattern is still running. So the surface muscles brace again. The energy crisis returns. The knot reforms.
This is why I see clients who have had excellent manual work done, sometimes for years, without getting ahead of the problem. The treatment is correct. The diagnosis of the knot is correct. But the upstream driver has not changed.
The psoas is a particular example worth noting. When the psoas is chronically shortened or guarded, it creates a chain of compensatory loading through the lumbar spine that generates trigger points in the quadratus lumborum, the lumbar paraspinals, and the glutes. Releasing those trigger points without addressing the psoas pattern produces short-lived results. The psoas work is not a replacement for trigger point therapy. Both have their role, and they belong in sequence.
The same logic applies to fascial release. When fascial restriction limits the movement available to a joint, the muscles working around that restriction will overload. Releasing fascial adhesions can dramatically change how a muscle holds tension, and trigger point work done after fascial release often produces faster and more durable results than trigger point work done alone.

Where Trigger Point Therapy Fits in the Program
At Fix Back & Neck Pain, trigger point therapy is one of seven techniques within manual and muscular therapy. It is not a standalone treatment here, and it was never designed to be. The assessment we do at the outset determines which techniques are indicated and in what order. Trigger point work, fascial release, psoas work, neuromuscular reeducation, and the rest are tools within a larger clinical logic, not individual sessions booked independently.
The structural piece that closes the loop is MedX spinal strengthening. This is not incidental to trigger point work. It is the part that addresses the underlying driver. When the deep lumbar and cervical extensors are genuinely strengthened through isolated, pelvic-stabilized loading on the MedX equipment, the compensation patterns that generate trigger points begin to resolve at the source. The surface muscles stop being asked to do what the deep stabilizers were built to do. The overload drops. The cycle breaks.
This is not a speculative connection. Pollock et al. (1989) documented that the deep lumbar extensors respond to training even at low volume: healthy subjects training just once per week increased isolated lumbar extension strength by 102 percent over ten weeks. The deep stabilizers, in other words, are trainable. Nelson et al. (1995) showed what that capacity means for people in pain. In an intensive, specific exercise program, 895 chronic low back pain patients were evaluated and 627 completed the program, and 76 percent of those who completed achieved excellent or good outcomes. These were not patients whose knots were released and then reappeared. Their underlying structural deficit was addressed.
Trigger point therapy is a meaningful and clinically valid part of getting there. It reduces the sensitization that makes movement painful, restores tissue quality, and creates a window for strengthening work to proceed without the inhibition that pain imposes. But it is a bridge, not a destination.
When Trigger Point Therapy Alone Is Not the Right Answer
Some presentations are genuinely suited to a course of trigger point therapy as a primary intervention: acute overuse, post-event soreness in an otherwise structurally sound athlete, isolated traumatic trigger points in healthy tissue with no underlying stability deficit. We refer these appropriately, and we say so.
What we see most often, though, is something different. Someone who has been in a manual therapy cycle for a long time, getting partial relief and partial recurrence, who has never had their lumbar or cervical extensor strength assessed. They do not know what their deep stabilizers are capable of, because no one has measured it.
That measurement is where we begin. Every assessment here starts with objective data before a program is built. If the trigger point work is what is needed, that is what gets recommended. If it is part of something larger, we say that clearly.
The first conversation is about understanding what is actually driving your pain — not selling you a treatment plan.
