When the Pain System Itself Becomes the Problem
Most people understand pain as a straightforward signal — tissue is damaged, the body sends a pain signal, and the pain resolves when the tissue heals. For many types of acute pain, this model is accurate. But for patients with chronic pain — pain that persists long after the expected healing time, that seems disproportionate to the injury, or that has no clear structural explanation — this model is insufficient.
Central sensitization is a well-documented neurophysiological phenomenon in which the central nervous system — the brain and spinal cord — becomes hypersensitive to input, amplifying pain signals beyond what the peripheral tissue is actually producing. The result is a pain experience that is real, that is physically driven, and that cannot be explained by imaging or standard structural assessment — because the primary driver is not in the tissue. It is in how the nervous system is processing and amplifying signals from the tissue.
Understanding central sensitization is one of the most important advances in modern pain science — and it is one of the most consistently absent concepts in standard musculoskeletal care. Patients whose pain doesn't fit a neat structural explanation are frequently told their pain is psychological, exaggerated, or untreatable. In most cases, neither is true.
At Bray Chiropractic & Wellness in Glastonbury, central sensitization is recognized as a clinical reality with identifiable features and a clear treatment framework — and it is integrated into the assessment and treatment of every chronic pain patient.
What Is Central Sensitization?
Central sensitization occurs when the central nervous system undergoes functional changes that lower the threshold for pain signaling and increase the amplitude of pain responses. These changes can develop in response to persistent peripheral pain input — a chronic injury that never fully resolves — or can be driven by other factors including psychological stress, sleep disruption, systemic inflammation, and metabolic dysfunction.
Key features of central sensitization include:
Allodynia
Pain in response to stimuli that are not normally painful — light touch, temperature changes, or pressure that would not bother a person without central sensitization.
Hyperalgesia
An exaggerated pain response to stimuli that are mildly painful — pain that is disproportionately severe relative to the input.
Referred pain and widespread sensitivity
Pain that spreads beyond the original injury site or affects multiple body regions simultaneously — often described as pain that moves around or that seems unrelated to any specific tissue problem.
Temporal summation
An increase in pain intensity with repeated stimuli — where the same input becomes more painful over time rather than less.
Poor response to peripheral treatment
Treatment directed exclusively at the peripheral tissue — adjustments, massage, exercise — produces limited or temporary results because the primary driver is central rather than peripheral.
Central Sensitization and Pelvic Floor Dysfunction
Central sensitization is particularly common in patients with chronic pelvic pain and pelvic floor dysfunction. The pelvic region has dense innervation and significant convergence of visceral and somatic pain pathways — making it particularly susceptible to central sensitization in the context of chronic pain.
Patients with chronic pelvic pain, dyspareunia, pudendal neuralgia, and persistent urinary urgency frequently have a significant central sensitization component alongside their peripheral pelvic floor dysfunction. Addressing only the peripheral pelvic floor — without recognizing and addressing the central sensitization component — produces incomplete results.
At Bray Chiropractic & Wellness, central sensitization assessment is integrated into the evaluation of all chronic pelvic pain presentations. Learn more about Pelvic Floor Dysfunction and Pelvic Pain.

Why Central Sensitization Is Frequently Missed
Several factors contribute to central sensitization being missed or dismissed in standard care:
Imaging doesn't show it. MRI and X-ray findings reflect structural tissue changes — they cannot show nervous system sensitization. Patients with significant central sensitization frequently have imaging that is normal or shows only minor age-related changes — and are told their pain has no physical basis when in fact it has a very real neurophysiological basis that imaging is not designed to detect.
It doesn't fit the structural model. Standard musculoskeletal care is organized around structural diagnoses — a disc herniation, a torn ligament, a joint space narrowing. Central sensitization doesn't fit this model, which means providers trained exclusively in structural assessment frequently miss it.
Symptoms seem inconsistent or exaggerated. The disproportionate pain responses, widespread sensitivity, and variable symptom patterns of central sensitization can appear inconsistent to providers who are not familiar with the condition — leading to the pain being dismissed as psychological or exaggerated when it is neither.
How Central Sensitization Is Addressed at This Practice
Treatment for central sensitization at Bray Chiropractic & Wellness is integrated into the overall care plan and is not a separate intervention. It involves several components:
Pain neuroscience education
One of the most evidence-supported interventions for central sensitization is education — helping patients understand what is happening in their nervous system, why their pain experience doesn't always correlate with structural findings, and how the nervous system can be recalibrated through targeted treatment. Patients who understand their pain at a neurophysiological level consistently show better outcomes than those who don't.
Addressing peripheral contributors
Reducing the peripheral pain input that is driving central sensitization — through chiropractic care, pelvic floor rehabilitation, soft tissue therapy, and dry needling — is an important component of reducing the central nervous system's sensitization state. Eliminating or reducing the source of ongoing peripheral nociception is one of the most effective ways to allow the central nervous system to begin to normalize.
Graded exposure and progressive loading
Patients with central sensitization frequently develop fear-avoidance patterns — avoiding activities and movements that have previously been painful. Graded exposure — carefully and progressively reintroducing feared movements and activities within a supportive clinical framework — is an important component of central sensitization treatment.
Clinical nutrition for neuroinflammation
Systemic inflammation — driven by dietary patterns, gut dysfunction, metabolic dysregulation, and lifestyle factors — contributes directly to central sensitization by maintaining a pro-inflammatory environment that lowers pain thresholds and perpetuates nervous system sensitization. Addressing nutritional contributors to neuroinflammation is one of the highest-yield interventions available for chronic pain patients with central sensitization. Learn more about Clinical Nutrition at this practice.
Sleep and lifestyle factors
Sleep disruption is one of the most significant drivers of central sensitization — and one of the most consistently ignored in standard pain care. While sleep management is not a direct clinical service at this practice, its role in central sensitization is addressed as part of the educational and lifestyle guidance provided to chronic pain patients.
How Chronic Pain With Central Sensitization Is Evaluated at This Practice
Assessment includes:
-
Detailed pain history — duration, distribution, character, behavior, prior treatment history, and response to prior treatment
-
Central sensitization screening — identifying features that indicate central nervous system involvement alongside peripheral contributors
-
Full musculoskeletal assessment — identifying and quantifying the peripheral contributors driving central sensitization
-
Pelvic floor assessment when pelvic floor dysfunction is a contributing factor
-
Nutritional and lifestyle assessment — identifying systemic contributors to pain persistence and sensitization
-
Functional assessment — evaluating fear-avoidance patterns and activity limitations
