Can Brain Retraining Actually Heal Chronic Illness? with Dr. Cathleen King (Ep 218)
Bendy Bodies with Dr. Linda BluesteinShow Notes
What if the reason your body keeps "betraying" you isn't one more undiagnosed disease, but a nervous system stuck in danger mode? Dr. Cathleen King was bedridden for over a decade before she discovered that the brain and vagus nerve might be the missing link behind POTS, mast cell flares, and chronic pain, and that you can start retraining them yourself.
In this episode of the Bendy Bodies Podcast, Dr. Linda Bluestein, the Hypermobility MD, talks with Dr. Cathleen King, physical therapist and founder of Primal Trust, about brain retraining, vagus nerve toning, and nervous system regulation for hypermobile Ehlers-Danlos syndrome (hEDS), POTS, mast cell activation syndrome (MCAS), long COVID, and ME/CFS.
Dr. King spent over a decade chronically ill and homebound before building the approach she now teaches. She explains the science of psychoneuroimmunology, the cell danger response, and polyvagal theory in plain language, and makes a careful distinction between taking responsibility for your healing and blaming yourself for being sick. She shares why she has patients tone the vagus nerve before brain retraining, why biohacking devices can backfire for highly sensitive people, how upper cervical instability can keep the body locked in alarm, and how a functional recovery is possible even while structural issues remain. Dr. Bluestein and Dr. King also discuss how to tell when a racing heart or a real MCAS trigger needs medical attention versus nervous system work, what to look for (and the red flags to avoid) when choosing a brain retraining program, and simple practices like near-far gaze and coherence breathing you can try today.

Takeaways:
Is "self-healing" real science or wishful thinking? The field of psychoneuroimmunology may explain how your brain state changes your immune system.
Can you recover your function while still having mold, Lyme, or joint instability? Dr. King says she did, and explains how.
Could upper cervical instability be keeping your whole body stuck in alarm mode? What EDS patients should know before trying eye exercises.

Are hypermobile EDS, MCAS, POTS, and dysautonomia actually becoming more common—or are we finally getting better at recognizing what has been there all along?
What if a child has joint instability but doesn’t actually look hypermobile? And when are “growing pains” a sign that something more is going on?

What if your hand pain, numbness, weakness, or grip problems aren’t actually coming from your hand or wrist? Orthopedic hand surgeon William Ericson, MD, joins Dr. Linda Bluestein to explain why people with Ehlers-Danlos syndrome (EDS) and hypermobility may experience overlooked median nerve entrapment near the elbow, carpal tunnel-like symptoms, thumb arthritis, and thoracic outlet syndrome—even when standard imaging or nerve testing doesn’t reveal the answer.
