Post-traumatic stress disorder (PTSD) is most commonly discussed in terms of its psychological symptoms — flashbacks, nightmares, emotional numbness, hypervigilance — but research on how trauma affects the body tells a more complete story that many people have never been given access to (Mayo Clinic). A significant portion of people living with the effects of trauma seek care for physical symptoms first: chronic pain, fatigue, digestive problems, or persistent tension they cannot explain, often from providers who are not looking for a trauma connection. At Life Works Professional Counseling, we think understanding the physical dimension of trauma is not a footnote — it is central to understanding the condition and to finding treatment that actually helps.
Why Trauma Lives in the Body
The stress response is a biological system, not only a psychological one. When a person encounters a perceived threat, the brain’s threat-detection center — the amygdala — triggers a cascade of physiological changes: stress hormones are released, the heart rate increases, muscles tighten, digestion slows, and the body mobilizes for action (National Institutes of Health). This is the fear response, and it is adaptive. It exists because it has helped humans survive threatening situations across evolutionary history.
In PTSD, this system becomes dysregulated. The amygdala’s threat response gets sensitized — calibrated to a threat environment that no longer exists in the present moment — and begins firing in response to stimuli that are associated with the original trauma rather than to genuine present danger. The physiological responses that were appropriate during a traumatic event become chronic: the body continues to behave as though the threat is ongoing, even when it is not (National Institutes of Health).
This is not a metaphor. The physiological changes involved in chronic threat activation are measurable and have real effects on the body over time. The nervous system stays in a state of elevated alert. Muscles that tense during a threat response may never fully release. The body’s normal rest-and-repair cycles are disrupted by sleep that is fragmented, too shallow, or interrupted by nightmares. These are not symptoms that exist separately from the trauma — they are the trauma, expressed in the body.
Physical Signs That Are Commonly Missed
PTSD and trauma responses include a recognized set of physical symptoms that people often do not connect to their traumatic experiences — particularly when those experiences happened long ago or are not the first thing they think of when considering what might be wrong (Mayo Clinic).
Trauma dysregulates the nervous system in two directions, and most people cycle between them rather than presenting as one or the other exclusively. Understanding both is important — because each looks very different from the outside, and each is frequently misidentified as something other than a trauma response.
Hyperarousal — a state of persistent heightened alertness — is one of the core symptom clusters in PTSD. Physically, this can manifest as an exaggerated startle response, muscle tension that does not fully release, difficulty falling or staying asleep, and irritability that seems disproportionate to circumstances. People experiencing chronic hyperarousal often describe it as simply being on edge all the time, without being able to explain why.
The opposite state is hypoarousal — sometimes called the freeze or shutdown response — and it is just as significant, though far less recognized. Where hyperarousal is the body in a state of fight-or-flight activation, hypoarousal is the body in collapse: a dorsal vagal shutdown in which the nervous system has moved beyond activation into a kind of protective stillness. Physically, this can look like profound fatigue that does not improve with rest, emotional numbness or flatness, feeling disconnected from the body, slowed movement or speech, difficulty initiating even simple tasks, and a pervasive sense of being shut down or checked out. People in a hypoarousal state are often told they seem withdrawn, unmotivated, or disengaged — and frequently attribute it to depression or personal failing rather than recognizing it as a physiological trauma response (Mayo Clinic).
The cycling between these two states — the agitation and hypervigilance of fight-or-flight alternating with the numbness and shutdown of freeze — is one of the most disorienting features of living with unresolved trauma. The nervous system moves between too much and too little, and neither state feels like baseline. Recognizing both poles as expressions of the same underlying nervous system dysregulation, rather than as separate or unrelated problems, is part of what effective trauma treatment needs to address.
Physical pain is also a well-documented feature of trauma responses. Headaches, chronic muscle pain, joint pain, and gastrointestinal symptoms — nausea, irritable bowel, digestive disruption — are all more common in people with PTSD than in the general population. The relationship between the brain and the experience of pain means that a nervous system in chronic threat activation is also a nervous system that may amplify pain signals.
Fatigue and difficulty concentrating are frequently attributed to depression, anxiety, or simply stress — and while those connections are real, they can also be expressions of a nervous system that has been running too hard for too long. The cognitive load of hypervigilance is significant: scanning for threat continuously, processing potential dangers, staying prepared for something bad to happen — all of this has an energy cost that shows up as exhaustion and cognitive fog.
Sleep disruption deserves its own mention. Nightmares are among the most recognized PTSD symptoms, but disrupted sleep in trauma responses is broader than that: difficulty falling asleep, waking frequently, or waking early and being unable to return to sleep are all common. Sleep is when the brain consolidates memory and the body repairs itself. When that process is chronically disrupted, everything else becomes harder — including recovery from trauma.
What This Means for Treatment
Understanding trauma as a body experience, not only a mind experience, has practical implications for what treatment needs to address. Talk therapy that engages only the cognitive and narrative dimensions of trauma — the story of what happened and the beliefs that formed around it — may leave the physiological dimension unaddressed. Many people find that they can understand their trauma intellectually without the body having caught up. The nervous system’s threat calibration does not update simply because a person has talked about what happened.
This is part of why we integrate somatic approaches — therapies that attend to physical sensation, body awareness, and the physiological dimensions of trauma — into our work at Life Works. Somatic work does not replace the cognitive and relational work of trauma therapy; it complements it by engaging the parts of the trauma response that live below the level of narrative.
For people whose trauma responses have not adequately resolved through talk therapy alone, ketamine-assisted psychotherapy (KAP) may be worth exploring. Research supports ketamine’s potential to produce rapid and significant reductions in PTSD symptoms, including hyperarousal and intrusive memories (National Institutes of Health). KAP at Life Works integrates ketamine medicine sessions with preparation and integration work, and our therapists incorporate somatic approaches within that framework where appropriate. KAP is an off-label use of ketamine — not FDA-approved specifically for PTSD — and whether it is appropriate for any individual depends on a thorough clinical evaluation. Results vary by individual.
Our team includes licensed clinical social workers and licensed professional counselors with experience holding the complexity of trauma presentations, including those where the physical dimension of the trauma response is prominent. Treatment planning at Life Works is collaborative, and we take seriously what your body has been telling you.
Two Barriers That Commonly Come Up
“I’ve seen multiple providers about these physical symptoms and nothing has helped. I’m not sure therapy is the answer.”
When physical symptoms have been investigated and no medical explanation has been found, trauma is not always the first place providers look — but it is worth considering. The physiological effects of chronic stress and trauma are real, and addressing the underlying nervous system dysregulation can, for some people, produce meaningful improvement in physical symptoms that have not responded to other treatment. We are not suggesting that therapy is a substitute for medical care; we are suggesting that the two are not mutually exclusive, and that addressing the trauma dimension of what you are experiencing may be a missing piece.
“I feel like I should be over this by now.”
The timeline of trauma recovery does not follow a calendar. How long it takes to process a traumatic experience is not determined by how much time has passed since it happened. Trauma that occurred years or decades ago can still be shaping the nervous system’s current response to the world. There is no expiration date on when trauma becomes worth addressing, and the sense that you should have moved on by now is often one of the more painful features of living with unresolved trauma — not a sign that treatment is no longer warranted.
Frequently Asked Questions
Can physical symptoms from trauma improve with therapy?
For some people, yes. When physical symptoms are driven or maintained by chronic nervous system activation related to trauma, treatment that addresses the underlying trauma response may help reduce those symptoms. Results vary significantly by individual, and we do not guarantee specific physical outcomes. Therapy is most effective when it is part of a broader picture that includes appropriate medical care where relevant.
What is somatic therapy and how is it different from regular talk therapy?
Somatic therapy refers to approaches that incorporate body awareness, physical sensation, and the physiological dimension of trauma into the therapeutic work. While traditional talk therapy focuses primarily on thoughts, narrative, and insight, somatic approaches also attend to how trauma is held and expressed in the body. At Life Works, somatic work is integrated into our trauma therapy rather than offered as a separate modality.
Is it common to not remember the trauma that is causing physical symptoms?
Yes. Trauma responses can develop in relation to experiences that are not fully consciously accessible — including early childhood experiences, or experiences that were dissociated at the time they occurred. A nervous system calibrated to a threat environment that can no longer be consciously identified is a recognized clinical presentation. You do not need complete memory of a traumatic event to experience its physiological effects, and you do not need complete memory to benefit from treatment.
How do I bring up physical symptoms in a therapy intake if I’m not sure they’re related to trauma?
Just describe them honestly. You do not need to arrive with a theory about what is causing your physical symptoms. Sharing what your body has been experiencing — the tension, the sleep disruption, the pain, the exhaustion — is part of the picture your therapist needs in order to understand what is happening. Let the clinical process do the work of making connections.
Can KAP help with the physical symptoms of PTSD?
Research suggests that KAP may produce reductions in PTSD symptom severity including hyperarousal, intrusive symptoms, and emotional reactivity (National Institutes of Health). Whether this translates to meaningful improvement in physical symptoms that are driven by those PTSD dimensions varies by individual. KAP is not a guaranteed treatment for physical symptoms, and whether it is appropriate for any individual requires a clinical evaluation.
Key Takeaways
- Trauma is a physiological event, not only a psychological one; the body’s stress response system can remain dysregulated long after the traumatic event has passed.
- Trauma dysregulates the nervous system in two directions: hyperarousal (fight-or-flight) and hypoarousal (freeze/shutdown); most people cycle between both states rather than presenting as one exclusively.
- Physical signs of hyperarousal include chronic muscle tension, sleep disruption, exaggerated startle response, and irritability; physical signs of hypoarousal include fatigue, emotional numbness, disconnection from the body, and difficulty initiating action — both are frequently misattributed to other causes.
- Treatment that engages only the cognitive dimension of trauma may leave the physiological dimension unaddressed; somatic approaches complement talk therapy by attending to how trauma is held in the body.
- KAP may be worth exploring for people whose PTSD symptoms — including physical manifestations — have not adequately responded to talk therapy alone; clinical evaluation determines appropriateness.
- Results vary by individual; if your body has been signaling distress that has not been explained by medical evaluation, the trauma connection is worth discussing with a qualified provider.
Your body keeps a record of what your nervous system has been through, and those signals are worth taking seriously. At Life Works Professional Counseling, we approach trauma as a whole-person experience and work with both the psychological and physical dimensions of how it presents.
