Chronic Pain and Central Sensitization

Pain that persists after tissues heal often reflects a sensitized nervous system. We calm the threat response first, then address neuroinflammation, sleep, gut, blood sugar, and pain-modulating brain networks.

What you may be noticing

Pain that has outlasted the original injury, or pain with no clear injury at all. It may wander from place to place. Light touch can hurt. Fatigue, poor sleep, brain fog, and anxiety travel with it. You may have heard that your scans are normal, which can feel like being told the pain is not real.

Your pain is real. Pain is always produced by the brain, and that does not make it imaginary. It makes it changeable. New neurological symptoms such as weakness, loss of bladder or bowel control, or sudden severe pain need prompt medical evaluation.

Why it is rarely one thing

Pain is an output of the nervous system, designed to protect. In central sensitization, the spinal cord and brain amplify signals, so ordinary input is experienced as threat. The volume knob is turned up.

Your brain also has its own volume control. A midbrain region called the periaqueductal gray coordinates descending pathways through the raphe nuclei, which release serotonin, and the locus coeruleus, which releases noradrenaline, to quiet pain signals at the spinal cord. The sympathetic output of the spinal cord, from a region called the intermediolateral column, rises when the system is on guard. Breathing, the vagus nerve, the vestibular system, and the cerebellum all feed these circuits, which is why precise, calming input can turn pain down.

Several layers keep the volume high. Neuroinflammation and activated immune cells in the nervous system sensitize pain pathways. Mast cell activation adds histamine-driven inflammation. Poor sleep lowers the next-day pain threshold, and blood sugar swings and a sluggish gut add physiological stress. Past injury, trauma, infections, and toxic exposures can contribute. The body cannot heal what the nervous system does not feel safe enough to process.

Patterns we look for

• Autonomic balance, sympathetic overdrive, and heart rate variability.
• Neuroinflammation, mast cell patterns, and inflammatory markers.
• Sleep architecture and circadian rhythm.
• Blood sugar regulation and fasting insulin.
• Bowel regularity, gut-brain axis, and intestinal permeability.
• Vestibular, cerebellar, and frontal function shaping descending pain control.
• Myofascial restriction, breathing mechanics, and pelvic floor tension.
• Thyroid, sex hormones, cortisol rhythm, vitamin D, magnesium, B12, and omega-3.
• Toxic burden, mold, and chronic infections when the history points there.

How I evaluate it

The comprehensive functional neurological exam assesses sensory processing, reflexes, eye movements, balance, autonomic responses, breathing mechanics, and frontal and cerebellar function, revealing how your brain is processing and modulating pain.

Functional labs may include inflammatory markers, a full thyroid panel, cortisol rhythm, fasting insulin, vitamin D, B12, magnesium, ferritin, sex hormones, and, when indicated, mast cell markers, mycotoxin testing, infection screening, or comprehensive stool analysis.

How we address it

• Calm the threat system first: diaphragmatic breathing with a soft pelvic floor, nasal humming with a long exhale, and simple grounding drills such as pressing the feet into the floor and releasing.
• Establish daily bowel regularity and steady blood sugar before deeper work.
• Restore deep sleep and circadian rhythm, among the most powerful pain modulators.
• Reduce neuroinflammation and mast cell load with targeted nutrition, without aggressive detoxification early on.
• Strengthen descending pain control with brain-based rehabilitation matched to your exam, including vestibular and cerebellar work, in short sessions that stay below your symptom threshold.
• Release myofascial restriction and retrain movement with hands-on care, physical therapy, and graded exposure.
• Explain how pain works, which itself reduces threat, and progress one variable at a time.

Progress often shows up first as better sleep, fewer flares, and more confidence in movement, before the pain itself fades. We track those early signals carefully, because they predict where the pain is headed.

A sensitized system can become less sensitive. The same plasticity that built the pain pattern can be guided away from it.
