Are There Side Effects to Myofascial Release Therapy?
By Michael Sudbury, LMT · 8 min read
If you have been considering myofascial release therapy, you have probably run into some version of this question — from a friend, from a forum, from your own hesitation. Are there side effects I should know about? Is this one more thing that's going to leave me feeling worse before it's over?
The short answer is no. Myofascial release is a non-invasive, non-injurious approach to the body when done properly. There are no pharmacological side effects. There is no forcing, no wrenching, no breaking through. When it is done well — and the John F. Barnes Approach™ we use at Release Works is among the gentlest hands-on approaches in existence — there is simply nothing being introduced to your body that could cause the kind of downstream effects the word "side effect" implies.
The longer answer is more interesting. Because while there are no side effects, there is something else — something that is often confused for one, especially by people who have never experienced it before.
It is called a healing response. And it deserves a proper explanation.
"Any modality that produces real change in the body will produce effects. That is the point. What matters is whether those effects are damage — or whether they are the body recalibrating."
Side Effects vs. HEALING RESPONSES.
A side effect is an unintended consequence of an intervention that was designed to do something else. Pain pills blunt your pain and come with nausea, constipation, dependency, liver strain. Steroid injections reduce inflammation and come with cartilage damage, weight gain, hormonal disruption. The side effects exist because the intervention is working against the body in some way while also trying to help it.
A healing response is different. It is the body doing what it is supposed to do — shifting, rebalancing, integrating, letting go — and occasionally letting you feel that process. Nothing is being forced. Nothing is being introduced. You are simply noticing the body's own work.
Most people who come to us have been living in a compensated, braced, adapted state for years or decades. When that state starts to change — when tissue that has been guarding since a surgery seven years ago finally softens, when a diaphragm that has not fully expanded in a decade takes its first full breath — the experience of that change is not always quiet.
That is the whole of what follows. Not warnings. Descriptions of what change can feel like, so you recognize it when you feel it.
What You Might NOTICE AFTER A SESSION.
Release Sensations
Myofibrils — the tiny contractile units of muscle tissue — can "let go" after sustained release. When they do, people describe it differently: a brief twitch, a flicker of electrical sensation, a wave of warmth, a feeling of tissue "peeling" as adhered layers separate. Some describe a "hurts-so-good" quality. None of these last long. All of them are signs the work is landing.
A Bruised Sensation Without a Bruise
Areas that have been restricted for a long time can feel tender to touch for a day or two afterward — even though no pressure was applied hard enough to actually bruise. The tissue is rehydrating and re-integrating. That sensitivity almost always resolves within 48 hours. If it lingers longer, mention it to your therapist.
Fatigue
This is the most common response. When long-held tension finally releases, the body often wants to rest. Muscles that have been bracing for years are exhausted — and when they stop bracing, you feel the exhaustion. Clients have taken naps in their cars before driving home. We encourage it. Fatigue is a reliable sign that something real has changed; it is not a problem to push through.
"The Pain Moved"
Occasionally, as the primary pain site eases, sensation shifts to somewhere else in the body — the opposite hip, the neck, the mid-back. It can feel as though the pain has "migrated." It has not. What actually happens is that the loudest signal in your body has gone quiet, and something that was already there — but masked by the louder pain — is now perceptible. This is useful information. It is often the next thing to address.
Rarely, new soreness shows up as the body adjusts to better alignment. Muscles that have not had to work in years are now being asked to work correctly; they can feel sore for a day or two as they recalibrate.
Dizziness, Nausea, or Mild Headache
Less common, but worth knowing about. Deep work with the sacrum, spine, diaphragm, or cranial base can influence the body's internal pressure and nervous system dynamics. As those systems recalibrate, some people experience transient dizziness, nausea, or a mild headache. These typically resolve quickly.
Two things to hold alongside this: first, we are not medical professionals and we do not diagnose. If you experience dizziness, nausea, or headaches that feel beyond ordinary or that do not resolve within a day or so, check in with your physician. Second, tell your therapist. We are here to guide you through the experience and adjust the approach if needed.
How Long Any of This LASTS.
Healing responses almost always resolve within 24 to 48 hours. Fatigue can extend a little longer if your body has been holding onto a particularly heavy load; we treat that as a sign the work is going deeper than usual, not as a problem.
If any sensation lasts longer than two or three days, or if something feels genuinely wrong rather than simply unfamiliar, reach out. Your therapist will walk through what has changed in your daily life — did you skip your self-care, overdo a hike, sit for eight hours on a plane, add new stress? — and help you understand what is happening. These are the signs a skilled practitioner uses to refine your protocol.
Who Myofascial Release IS REALLY FOR.
Conventional medicine is extraordinary in an emergency. When the situation is acute and life is on the line, there is nowhere you would rather be than in the hands of a good surgeon or emergency team. But for chronic conditions — the kind that have quietly built over decades and do not show up cleanly on imaging — the standard toolkit runs out quickly. Pain medication dulls the signal. Injections buy a window. Surgery addresses a visible finding. None of them work on the connective tissue system that surrounds and organizes everything in your body.
That is where myofascial release earns its place. It is particularly effective for people whose pain has not responded to the usual interventions — chronic pain, fibromyalgia, chronic fatigue, myofascial pain syndrome, and the long list of "I have tried everything" conditions that conventional care tends to shrug at.
You do not need a diagnosis to benefit. If you have an area of nagging tension, stiffness, or pain that will not let go, this approach addresses the layer most other approaches never touch. Most clients tell us they sleep better, move more freely, and feel younger in their own body within the first few protocols — often in areas they were not even trying to address.

What This Is Not — AN IMPORTANT DISTINCTION.
We are not here to replace your medical care. We are not prescribing, diagnosing, or treating any specific condition. What we do is help the body do something it was already trying to do — reorganize, release, and return to a more functional baseline.
If you are on medication, stay on your medication and work with your physician on any decisions about it. If you have an active diagnosis, we are happy to work alongside your care team. The Release Works Method of Healing™ is a movement restoration practice, and it belongs in the larger picture of your health — not in opposition to it.
