The Biology of Trauma® With Dr. Aimie What Does Overwhelm Have To Do With Chronic Pain?
If you have chronic pain, you've probably been told that stress is making it worse. But here's what the biology actually shows: by the time your pain is flaring, you're past stress. You've crossed into overwhelm — and that changes everything about what your body can do.
In this episode, Dr. Aimie Apigian — double board-certified physician and author of The Biology of Trauma® — explains why chronic pain and chronic trauma follow the same biological pattern, and exactly how the body gets stuck in cycles that feel impossible to interrupt.
Once the nervous system crosses the critical line of overwhelm, three survival strategies take over: dissociation, immobilization, and energy conservation. Healing goes offline. That's not a failure of your approach. That's a shift in operating mode — one where the body only has enough energy to survive.
What determines whether a flare happens is neuroception — the nervous system's subconscious safety scan, running below conscious awareness at all times. When it reads threat, the physiology shifts. That shift is where chronic pain lives.
What moves this pattern is building capacity through five specific nervous system skills — so the body spends more time below the line, where healing is actually possible.
In This Episode You'll Learn:
- [00:00] Why chronic pain is an overwhelm problem — not a stress problem
- [01:34] How pain becomes chronic and why it follows the same biological pattern as trauma
- [03:06] Stress is not trauma and trauma is not stress
- [03:20] What the critical line of overwhelm is — and why the body stays braced long after the danger is gone
- [05:59] The Loop and what it does to the body's healing mechanisms
- [08:11] How adrenaline suppresses pain during stress — and what happens when it's removed in overwhelm
- [08:49] What microglia are and why they follow the same threshold pattern as the nervous system
- [09:30] The three survival strategies the body activates past the critical line — dissociation, freeze, and energy conservation
- [11:40] What neuroception is and why it controls whether a pain flare happens
- [13:42] Why capacity — not stress — determines where your critical line sits
- [15:10] The five nervous system skills that build capacity before the line is crossed - that every adult and every person with chronic pain needs to know — what each skill does and why it matters
- [17:44] Why we only go as fast as the slowest part of me feels safe to go
- [18:44] How to interrupt a chronic pain cycle before it crosses the line
