A Hidden Link Between Fibromyalgia and Trauma
For decades, fibromyalgia has confounded doctors AND patients. A condition marked by chronic, widespread pain, fatigue, and cognitive disturbances, it has long been relegated to the fringes of medical understanding. Many sufferers, predominantly women, have been dismissed with vague and – sometimes – disturbing – diagnoses, offered antidepressants, or told the pain is all in their heads. Emerging research is uncovering a startling connection that may change how we understand and treat the condition: fibromyalgia may be deeply intertwined with trauma.
A Mysterious Illness with Elusive Causes
Fibromyalgia affects an estimated four million Americans, with women more frequently affected. The condition, which often presents alongside irritable bowel syndrome, migraines, and depression, has no clear biological marker. While some researchers have linked it to abnormalities in pain processing, the underlying causes remain hotly debated.
Some of the most compelling new research suggests that fibromyalgia may be a disorder of the nervous system, exacerbated by past trauma. A growing body of evidence indicates that early-life adversity, including childhood abuse, neglect, and even adult trauma such as post-traumatic stress disorder (PTSD), can rewire the brain’s response to pain and stress, setting the stage for chronic illness later in life.
Trauma’s Long Shadow
The connection between trauma and fibromyalgia is not a new idea. In the late 20th century, Dr. John Sarno, a controversial but widely read physician, theorized that repressed emotional pain could manifest physically, a concept he termed Tension Myoneural Syndrome. While many of his claims were dismissed by the medical establishment, modern neuroscience is now validating his theory.
Studies have shown that people with fibromyalgia are significantly more likely to have a history of trauma than those without the condition. A landmark 2018 study published in The Journal of Pain found that nearly half of fibromyalgia patients reported experiencing severe childhood trauma. Another study, in Arthritis Care & Research, found that PTSD was significantly associated with fibromyalgia, with many patients reporting an overlap between symptoms of both conditions.
The mechanism behind this link lies in the way trauma alters the nervous system. When the body experiences extreme stress—whether physical, emotional, or psychological—it can enter a prolonged state of hypervigilance. This state, often referred to as dysautonomia or central sensitization, leaves the nervous system stuck in overdrive. In practical terms, this means an increased sensitivity to pain, heightened stress responses, and an inability to return to a relaxed baseline state. Over time, this heightened sensitivity can solidify into the chronic, unrelenting pain of fibromyalgia.
The Brain-Body Connection
Neuroscientists have identified several key mechanisms that may explain how trauma contributes to fibromyalgia. The amygdala, the brain’s fear-processing center, becomes hyperactive in those with PTSD and trauma histories. This, in turn, influences the hypothalamic-pituitary-adrenal (HPA) axis—the body’s stress-regulation system—which can dysregulate pain perception and immune function.
Additionally, the brain’s neurotransmitter balance is often disrupted in fibromyalgia patients. Serotonin, a key mood and pain regulator, is frequently depleted, while substance P, a neuropeptide that amplifies pain signals, is elevated. These changes mirror those seen in individuals with PTSD, suggesting a shared neurological basis.
Breaking the Cycle
If fibromyalgia is rooted in trauma, what does that mean for treatment? While traditional approaches—painkillers, antidepressants, and physical therapy—have provided limited relief, trauma-informed treatments may offer new hope for lasting change.
One promising area is somatic therapy, which focuses on rewiring the nervous system’s response to pain and stress. Techniques such as somatic experiencing and eye movement desensitization and reprocessing (EMDR) have shown success in treating trauma-related disorders and may help alleviate fibromyalgia symptoms. Additionally, mindfulness-based stress reduction (MBSR) has been found to reduce pain and improve quality of life in fibromyalgia patients, possibly by calming an overactive nervous system.
Medication, too, may be more effective when targeted at the nervous system. Low-dose naltrexone, for instance, is being touted for its ability to modulate pain perception in fibromyalgia patients, while certain anticonvulsants, such as gabapentin, may help stabilize the nervous system.
Most crucially, recognizing fibromyalgia’s link to trauma can provide patients with validation—an acknowledgment that this pain is real, that it is rooted in the body’s response to past adversity, and that healing is possible.
A New Understanding
Fibromyalgia has long been a medical mystery, but its connection to trauma offers a foundational shift in how to approach it. By viewing the condition through the lens of the nervous system and trauma, we can move beyond managing symptoms to a place where addressing root causes might be better resolved.
For those who have suffered in silence—dismissed, disbelieved, or told their pain is imagined—this emerging research may be a new promise that these sufferers experiences matter, and that healing is within reach.
