Chronic Pain Fundamentally Misunderstood, Says Leading Pain Scientist

Chronic pain impacts approximately one in three individuals globally. If you have endured it, you understand it fluctuates throughout the day. This discomfort often intensifies when stress or focus brings it to the forefront of your mind, then diminishes during relaxation or distraction, such as watching television. This pattern indicates pain regulation extends beyond mere symptoms in the affected area; it is significantly governed by the brain. Yet, medical consultations typically begin with the question: "Tell me where it hurts."
Debunking the Myth of Pain Localisation
This phrase titles a new book by Dr Rachel Zoffness, a prominent pain scientist and assistant clinical professor at the University of California, San Francisco, with thirty-five years of research and treatment experience. "We have all been told that pain resides solely in our tissues, within the body part that hurts. However, we know this is false," she states. "My objective is to clarify why rejecting this myth is crucial."
Here are her insights from a lifetime dedicated to studying pain, along with cost-free protocols anyone can implement to alleviate it.
Common Misconceptions About Pain
"Pain is an equal opportunist—it affects everyone, whether through childbirth, injury, or ageing," Dr Zoffness explains. The brain constructs pain as the body's early warning system against potential harm or dangerous behaviour, responding to numerous inputs beyond physical damage. "I am not dismissing tissue damage; it matters, but it does not complete the picture," she continues. "The brain processes data from the injured area, certainly, but also from emotions, social health, and environment."
For instance, research reveals that many individuals with physical abnormalities like slipped discs, desiccated discs, or twisted spines—commonly linked to back pain—report no pain whatsoever. In Dr Zoffness's words: "This demonstrates pain and tissue damage are distinct entities."
This underscores the significance of emotions, social health, and environment in pain perception. We can modify these factors to lessen discomfort by reducing stress, enhancing sleep, socialising, improving diet, or other means, she notes. "We know brain regions responsible for emotions also generate pain," says Dr Zoffness. "Every physical sensation filters through the brain's emotion centres before becoming pain, an experience familiar to all. Our bodies ache more when stressed, anxious, or depressed."
"The connection between emotional and physical health is intuitive. Yet, visiting a doctor for pain rarely involves questions about emotional well-being."
Why Chronic Pain Is Pervasive and Increasing
"Pain is a biopsychosocial phenomenon," Dr Zoffness asserts. It exists at the intersection of biological, psychological, and sociological factors in a Venn diagram.
Biological elements are most recognised: genetics, tissue damage, inflammation, system dysfunction, diet, exercise, and sleep. However, the brain substantially influences pain presentation, exemplified by the placebo effect. Social aspects, including healthcare access and loneliness, also contribute.
"I want people to realise that focusing solely on the biological domain ignores two-thirds of the pain problem," says Dr Zoffness. "Globally, 1.9 billion people live with chronic pain, explaining why this figure persists."
"... I treat adolescents as young as sixteen who have been bedridden since age twelve. I am not a magician, but these patients recover, leave bed, and resume their lives. Previously, they received only pills."
"We possess the scientific knowledge. Why do we continue mistreating pain so severely? Could it be due to a profit-driven healthcare system reliant on selling pills and procedures?"
Practical Strategies to Reduce Pain
To diminish pain, Dr Zoffness first recommends identifying your "high pain recipe," comprising elements that exacerbate your discomfort. She details this approach in her book, Tell Me Where It Hurts.
"Ingredients in the high pain recipe derive from our biopsychosocial menu," she explains. "For example, my high pain recipe includes: prolonged screen time; neglecting physical movement and exercise; overcommitting without refusal; high stress; extended isolation; poor nutrition; and inadequate sleep, a major pain predictor for me."
Everyone recognises factors that worsen their condition, from stress to inclement weather, Dr Zoffness notes. However, she argues that if a high pain recipe exists, so must a low pain recipe.
"Numerous ingredients are adjustable," she emphasises. "This message is vital, especially for chronic pain sufferers who often lose hope. They are told pills are the solution, then feel devastated, alone, and abandoned when medications fail. This should never occur."
If unsure where to begin, use these pillars to identify high pain recipe components:
- Injury
- Sleep
- Diet
- Movement/exercise
- Emotional health
- Social health
Your high pain recipe contains factors contributing to discomfort. To alleviate pain, make adjustments in each area to shift behaviours toward your low pain recipe. This might involve improving sleep hygiene, exercising regularly, daily outdoor time, consuming more vegetables, safeguarding emotional health, or allowing time to unwind.
Recovering from Injury with Appropriate Pacing
If you are a recreational runner, you would not attempt a marathon immediately; you would gradually increase distance over time. Similarly, a gym-goer would not bench press 120kg suddenly but build strength incrementally. The body adapts brilliantly, yet change requires time.
Thus, recovering from pain or injury should not expect immediate transition from high to zero pain. Recovery must be paced suitably according to bodily capacity, Dr Zoffness advises. "Pacing for pain resembles marathon training pacing," she continues. "With chronic pain patients, we always start comfortably."
"From there, they select an activity to resume—running, tennis, football, baking—then we develop a pacing protocol, adding activity time weekly with rest breaks."
Distinguishing Chronic and Acute Pain
Acute pain lasts three months or less; chronic pain persists beyond three months. These concepts require different treatment, Dr Zoffness states. "If you trip while running and your ankle hurts, I absolutely want you to stop, rest, seek help, scan for fractures," she clarifies. "However, chronic pain is recognised as a central nervous system disease—involving the brain and spinal cord."
"One process chronicifying pain is central sensitisation. This means your brain and spinal cord become sensory super detectors or megaphones, amplifying minor sensory data from your body."
She uses a car alarm analogy: a cyclist passing your car triggers a deafening alarm despite no damage, based on subtle disturbance detection.
"With chronic pain, the tissue damage-pain link weakens significantly because pain no longer indicates bodily damage," Dr Zoffness says. "Chronic pain signals need to examine your brain and focus on neuroplasticity: how to alter your brain and nervous system to reduce pain?"
Why does pain localise to areas like back, knee, or shoulder? "That is the most confounding question ever, in my view," Dr Zoffness responds. "It might involve genetic predisposition, but no one knows."
The Place of Surgery and Medication
Pain medications and surgeries remain important in healthcare. "For acute pain, medications and surgeries save lives and enable procedures like organ transplants," says Dr Zoffness. She objects when they are the primary or sole solution for chronic pain.
With chronic pain, pain medications can be part of a low pain recipe, Dr Zoffness notes. Yet they are often over-relied upon and should not be the only intervention offered—far from it.
The Reality and Hope in Pain Management
A magic pill eliminating pain entirely is appealing but non-existent. This is the bad news. "There is no quick fix—that is the unfortunate truth," says Dr Zoffness. "Most people dislike hearing this, so daily, newfangled magic pain treatments emerge, all deceptive."
However, the key takeaway is promising. "Treating pain, especially chronic pain, is highly hopeful because numerous ingredients are within our power to tweak and change," Dr Zoffness affirms. "We require no prescription, minimal money, and it is achievable for anyone. I hope readers feel empowered after this article."
