Have you been diagnosed with POTS (Postural Orthostatic Tachycardia Syndrome) or dysautonomia yet no one can explain why you developed it?
You’ve probably tried:
- Cardiology
- Neurology
- GI specialists
- Endless labs and imaging
And you still don’t feel right.
What if the root of your symptoms isn’t in your heart or brain but in your neck?
At DMX Miami, we specialize in detecting cervical instability, especially at the upper cervical levels (C0–C1–C2), where the brainstem and vagus nerve reside. Using Digital Motion X-Ray (DMX), we uncover ligament damage that often causes or worsens autonomic dysfunction and is completely missed by standard MRIs and CT scans.
Why Your Neck May Be Causing Autonomic Chaos
Your autonomic nervous system controls:
- Heart rate
- Blood pressure
- Digestion
- Breathing
- Body temperature
- Energy levels and alertness
The vagus nerve which governs much of this system passes through the upper neck, right near the atlas (C1) and axis (C2) vertebrae.
When ligaments here are unstable or damaged, it can cause:
- Mechanical irritation of the vagus nerve
- Poor blood flow to the brainstem
- Excessive or insufficient nerve signaling
- Miscommunication between your brain and body
This leads to symptoms like:
- Rapid heart rate when standing (POTS)
- GI problems (nausea, bloating, constipation)
- Dizziness, lightheadedness, or fainting
- Heat intolerance or cold extremities
- Fatigue and brain fog
- Chest tightness, palpitations, or shortness of breath
What Is Digital Motion X-Ray (DMX)?
DMX is a dynamic X-ray study that captures your spine in motion.
It records 30 real-time frames per second as you gently move your head through flexion, extension, rotation, and lateral bending.
DMX reveals:
- Ligament laxity at C0–C1–C2
- Abnormal vertebral movement
- Cervical instability missed by MRI
- Motion patterns that correlate with symptoms
If your POTS or dysautonomia symptoms worsen with neck movement, upright posture, or after injury DMX can show you why.
Who Gets POTS from Cervical Instability?
We often see this link in:
- Post-concussion or whiplash patients
- Young women with EDS/hypermobility
- People who developed POTS after trauma
- Patients with normal heart and brain scans
- Individuals whose symptoms worsen when upright
- Those misdiagnosed with anxiety or psychosomatic conditions
DMX gives these patients validation and a path forward.
