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. This episode is for educational purposes only and is not a substitute for personalized medical advice. 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.
