Pain Built in the Brain: A Biopsychosocial Roadmap to Chronic Pain

Pain is not just a signal from a damaged body part but a brain-built experience. In this interview, pain scientist Rachel Zofnus explains the biopsychosocial model of pain, why chronic pain can persist even after tissue heals, and how the brain, emotions, environment, and social context shape the pain we feel. Central sensitization and neuroplasticity illuminate how pain becomes persistent, while strategies spanning sleep, nutrition, stress management, and social support offer realistic paths to reduce pain without relying solely on pills or procedures. The discussion also examines the misperceptions surrounding pain treatment and the importance of educating clinicians to treat pain as a biopsychosocial phenomenon.

Introduction

Pain is often perceived as a simple bodily signal, but the podcast challenges this view by presenting pain as a brain-centered experience that integrates biological, psychological, and social factors. "Pain is our body's warning system." - Rachel Zofnus.

The host and guest discuss how pain sits at the crossroads of neuroscience, behavior, and society, and why understanding pain as a biopsychosocial process changes how we approach treatment.

Biopsychosocial Model: A Unified View of Pain

The core idea, reiterated throughout the conversation, is that pain is never purely physical or mental; it lives in the intersection of three overlapping domains: biology, psychology, and social context. The bio domain includes genetics, tissue states, diet, sleep, and activity; the psych domain covers emotions, expectations, coping styles, and the placebo effect; and the social domain encompasses access to care, race, socioeconomic status, and social support. This framing offers multiple avenues to reduce pain, not just surgery or medication.

"Pain is always biopsychosocial." - Rachel Zofnus.

From Acute to Chronic Pain: The Brain’s Role

The podcast explains central phenomena that turn acute pain into chronic pain, notably neuroplasticity and central sensitization. The brain learns to magnify pain signals over time, so even after an injury heals, the pain pathway remains highly responsive. The analogy of practicing a skill helps illustrate how repeated activation strengthens pathways, making pain more likely to persist if the brain stops dampening signals. This concept reframes chronic pain as a disease of the nervous system, not just a symptom of tissue damage.

"Chronic pain is a disease process in its own right, and the brain has become sensitive, central sensitization has occurred." - Rachel Zofnus.

Clinical Implications and the Pain Protocol

The discussion moves to actionable strategies under the biopsychosocial framework. The three pillars—bio, psycho, and social—are translated into discrete, achievable steps. In the bio domain, sleep hygiene, nutrition, and exercise are highlighted as real levers to reduce pain volume. In the psycho domain, attention turns to emotions, stress management, coping styles, and the predictable influence of mood on pain. In the social domain, reducing isolation and improving social support, boundaries, and access to care are emphasized as critical for pain relief. The host and guest discuss how a practical, patient-centered protocol can empower people with pain and complement medical treatments that focus on anatomy and physiology.

They also touch on the role of hypnosis, which has evidence for pain reduction, though it requires careful framing and provision by trained clinicians. A caution is offered about labeling pain as “all in the head,” reinforcing that pain is always both physical and psychological, not either/or.

Hypnosis, Placebo, and Pain Management

The guest notes that clinical hypnosis, when administered by a care provider, can reduce pain by engaging multiple aspects of the pain recipe, including emotions and expectations. The discussion also clarifies that hypnosis should not be dismissed as mere trickery; it is a recognized medical technique with measurable effects for many patients.

"Hypnosis really needs major rebranding." - Rachel Zofnus.

Systemic Challenges and the Path Forward

Beyond individual strategies, the podcast addresses larger issues in pain management, including the overreliance on opioids and the profits that can distort treatment. It is highlighted that a vast majority of medical schools offer little compulsory pain education, and most emphasize a biomedical model rather than a full biopsychosocial approach. This gap leaves clinicians underprepared to treat pain comprehensively, underscoring the need for better education and resources for both patients and providers.

"96% of medical schools in the United States have zero dedicated compulsory pain education." - Rachel Zofnus.

Practical Takeaways and Hopeful Outlook

Ending on a constructive note, the podcast outlines how individuals can begin applying the biopsychosocial framework today, through improved sleep, stress management, social connections, and careful engagement with healthcare providers. The message is one of hope: even when surgery or drugs aren’t the answer, there are many evidence-based avenues to reduce pain and improve function, rooted in brain-body-environment–level changes.
