PTSD as a Nervous System Disorder: What No One Told Me
I never thought of PTSD as a nervous system disorder — until one day in therapy, my psychologist gently said:
“Sarah, you’ve got a nervous system disorder. PTSD lives in your body, not just your mind.”
That sentence landed like a truth I had always known but didn’t have the words for. Suddenly, it all made sense — the chronic tension, the health flare-ups, the feeling that I was constantly bracing for impact.

When Trauma Lives in Your Body: My Wake-Up Call
A few years ago, a fuel tanker ran into the back of my car. The impact caused a disc bulge in my lower back and neck. I did everything I could — physio, Pilates, cortisone injections. I was disciplined with my rehab. The pain became chronic, but manageable.
But recently, I had a terrifying flare-up.
I woke up in excruciating pain — vomiting, shaking, unable to move my neck. I hadn’t done anything strenuous. It was a rest day. Nothing happened in my sleep. I hoped it would pass. It didn’t.
At the hospital, I was dizzy and had dangerously low blood pressure. My nervous system was shutting down.
The MRI showed a second disc bulge, likely caused by instability from the first. But here’s what I’m realising now: the physical injury wasn’t the whole story.
My nervous system was overwhelmed.
Science Break: It’s Not You — It’s Your Nervous System
If you’ve ever felt like your body is betraying you — like you’re too emotional, too tired, too reactive — you’re not crazy. You’re not weak.
You’re dysregulated.
And science backs that up.
Here’s what we know:
- PTSD rewires the brain. It overstimulates your amygdala (fear center), shrinks your hippocampus (memory), and dulls your prefrontal cortex (logic and regulation).
- Your autonomic nervous system — the one that controls heart rate, digestion, stress — gets thrown off. You can swing between hyperarousal (panic, anger, insomnia) and hypoarousal (fatigue, numbness, low BP).
- Dr. Bessel van der Kolk, author of The Body Keeps the Score, explains that trauma is stored not just in memory, but in the body’s cells and systems.
- Symptoms like inflammation, gut issues, dizziness, chronic pain, and even autoimmune disorders are increasingly linked to long-term nervous system dysregulation.
Analogy: Your Nervous System Is a Smoke Alarm That Won’t Turn Off
Think of your nervous system like a home smoke alarm.
In a safe, functioning system, it only goes off when there’s fire.
But with PTSD? The wires are fried. The alarm goes off for burnt toast… or nothing at all.
That’s why you might feel unsafe even when you’re “fine.” That’s why your body shakes, your stomach flips, or your blood pressure drops out of nowhere.
It’s not you. It’s your system trying to protect you.
The Physical Cost of Unprocessed Trauma
I’ve been burning out slowly since I joined the Police.
I’ve survived a car crash, witnessed trauma on the job, and endured emotional damage in my personal life. And while I’ve kept going — training, eating well, being disciplined — I now see:
👉 My body has been in survival mode for years.
👉 My chronic pain wasn’t just structural — it was emotional residue.
👉 My immune issues, sleep problems, and inflammation were red flags.
My nervous system had enough. It hit the wall — and took me down with it.
“Healing begins where safety is restored — in your body, in your breath, and in your sense of self.” – Sy (The Inner Growth Path)
Healing Is Holistic (and Not Linear)
I’ve done the talk therapy. It’s helped.
But it wasn’t enough.
What’s actually helped me feel human again are the somatic practices:
- Breathwork
- Sound healing
- Ecstatic dance
- Trauma-informed massage
- Vagus nerve regulation
- Journaling & grounding rituals
- Real, ceremonial cacao (not the sweet stuff — the bitter kind that cracks your heart open)
When I stopped doing those, I felt it. And my body really felt it.
This Isn’t Mine to Carry Anymore — And Maybe It’s Not Yours Either
Some of the pain I’ve been carrying isn’t even mine — it’s energy and trauma from the job, from my ex, from the world around me. And I finally realise:
I don’t have to keep carrying it.
This is my commitment to myself — and maybe yours too:
- Prioritise nervous system care.
- Make somatic healing a regular part of life.
- Let go of other people’s pain.
- Ask for support.
- Stop trying to “act fine” when your body is screaming for help.
Looking for Support Between the Sunshine Coast and Gold Coast?
I’m seeking genuine, trauma-informed practitioners who don’t just wear the healer title — they embody it. If you know someone with integrity, empathy, and a real intuitive gift, please reach out. I’d love to try more modalities and share what I learn.
Let’s Heal Together
There’s always grief in becoming a different version of yourself — especially when that change was forced by trauma. But there’s also strength.
If you’re on this journey too, I see you.
Stay tuned — I’ll keep sharing what works, what doesn’t, and the reality of walking through trauma with your body as your guide.
Facts (Science-backed):
- Studies show trauma can reduce heart rate variability, increase inflammation markers, and disrupt the gut-brain axis (Source: Harvard Health).
- PTSD shrinks the hippocampus (responsible for memory and emotional regulation) and overactivates the amygdala (fear center).
- The vagus nerve plays a vital role in calming the body after stress. Breathwork and cold exposure stimulate this nerve to downregulate the nervous system.
- Chronic stress contributes to autoimmune issues, fibromyalgia, chronic fatigue syndrome, and more (Source: NIH, Mayo Clinic).
FAQs About PTSD and the Nervous System
What does PTSD do to your nervous system?
PTSD dysregulates your autonomic nervous system. It often leads to chronic hyperarousal (fight-or-flight), difficulty calming down, low heart rate variability, and somatic symptoms like pain, fatigue, and dizziness.
Can trauma really be stored in the body?
Yes. Research shows that trauma can be stored in the muscles, fascia, and nervous system. This is why people may experience chronic pain, tightness, or numbness long after the traumatic event has passed.
What are the physical symptoms of PTSD?
Common symptoms include chronic pain, fatigue, digestive issues, inflammation, sleep disruption, dizziness, tension, headaches, and autoimmune flare-ups. These are signs of a dysregulated nervous system.
How do I regulate my nervous system after trauma?
Practices like breathwork, somatic therapy, vagus nerve exercises, sound healing, gentle movement, trauma-informed massage, and grounding techniques can support nervous system regulation.
Is somatic healing effective for PTSD?
Somatic healing has been shown to be effective for many people with PTSD. It focuses on body-based techniques to process stored trauma, which complements talk therapy by addressing the physiological impact of trauma.
