Chronic Pain and Fibromyalgia

Chronic Pain Is Not All in Your Head — But It Does Live in Your Nervous System

If you've been told your pain is psychological, that you should try harder to relax, that you need to learn to live with it, or that there's nothing structurally wrong so there can't be anything truly causing it — you've encountered the limits of a medical model that still struggles with chronic pain. The pain is real. The mechanism is real. It's just not where most people are taught to look for it.

Modern pain science has documented something that radically changes how chronic pain should be approached: the nervous system itself can become the source of pain. Tissues may have healed years ago, imaging may look normal, and yet the pain continues — not because something is wrong with the tissue, but because the nervous system has learned the pain so thoroughly that it now generates the signal on its own. This is called central sensitization, and it sits at the heart of fibromyalgia and most chronic pain syndromes.

Understanding this changes everything about treatment. You can't fix a nervous system pattern by injecting cortisone into a joint. You can change a nervous system pattern — with the right combination of inputs, repeated consistently, over enough time.

What's Actually Happening in Chronic Pain and Fibromyalgia

Acute pain is straightforward: tissue damage activates nociceptors, signal travels to the spinal cord, then to the brain, and you experience pain. The pain resolves as the tissue heals. Chronic pain is a different beast.

In central sensitization, the spinal cord and brain become hyperreactive. The dorsal horn of the spinal cord — where pain signals first synapse — ramps up its sensitivity. Signals that should produce mild discomfort produce severe pain (hyperalgesia). Stimuli that should produce no pain at all produce pain (allodynia). Pain spreads beyond the original area of injury. The brain regions that process pain become more active, more interconnected, and harder to quiet.

The descending pain modulation system — the brain's built-in pain dampening mechanism — weakens. Normally, signals from the brainstem release endogenous opioids, serotonin, and norepinephrine that quiet incoming pain signals. In chronic pain syndromes, this system underperforms, so less pain gets filtered out before it reaches conscious awareness.

The HPA axis is dysregulated. Chronic pain patients commonly show abnormal cortisol patterns — sometimes flattened, sometimes reverse, sometimes blunted in response to stressors. This affects inflammation, sleep, energy, mood, and pain processing in interconnected ways.

Mitochondrial dysfunction appears in muscle and other tissues of fibromyalgia patients. Reduced energy production at the cellular level contributes to the muscle fatigue, post-exertional malaise, and pain that characterize the syndrome.

Small fiber neuropathy has been identified in a significant percentage of fibromyalgia patients on skin biopsy — finally giving a measurable peripheral correlate to a syndrome that was long considered purely central. This finding has changed how some researchers conceptualize fibromyalgia and opens up treatment angles aimed at small fiber recovery.

Sleep architecture is consistently disrupted in chronic pain. Restorative deep sleep gets fragmented; alpha-wave intrusions appear in slow-wave sleep. Sleep that doesn't restore the nervous system perpetuates pain processing dysfunction the next day.

What Drives Chronic Pain

Unresolved peripheral pain inputs. Trigger points, joint dysfunction, scar tissue, post-surgical adhesions, low-grade inflammation — any persistent peripheral source feeds the central sensitization pattern. Treating the periphery is part of treating the center.

HPA axis dysregulation and chronic stress. Pain and the stress response share neurochemistry. Chronic activation of the stress system amplifies pain perception and weakens descending modulation. Treatment that ignores the nervous system layer treats half the problem.

Sleep disruption. Inadequate restorative sleep is both a symptom of chronic pain and a driver of it. Improving sleep quality is non-negotiable for chronic pain recovery.

Gut and metabolic inflammation. Systemic inflammation lowers the threshold at which pain signals fire. Gut dysbiosis, food sensitivities, blood sugar dysregulation, and metabolic syndrome all contribute. Patients with chronic pain who clean up their gut and metabolic picture often see meaningful improvement.

Trauma and nervous system patterning. Adverse childhood experiences, accidents, chronic high-stress environments, and emotional trauma all shape how the nervous system responds to threat — including the threat signal of pain. This is not the same as saying pain is psychological. It's saying the nervous system carries a history, and that history affects pain processing.

Nutritional deficits. Magnesium, vitamin D, B vitamins, and omega-3s are commonly low in chronic pain patients. Each plays a role in nervous system function and inflammation. Repletion isn't a cure but is part of the foundation.

Hormonal factors. Thyroid dysfunction (especially low T3), low DHEA, low progesterone in perimenopausal women, and low testosterone in men all affect pain perception and recovery capacity. These are testable and addressable.

Where TCM Comes In

Chinese medicine has been treating chronic pain syndromes for centuries, with pattern frameworks that map well onto the modern picture.

Liver Qi Stagnation. Pain that worsens with stress, accompanied by tension, irritability, and a sense of being stuck. Maps onto the sympathetic-overdrive component of central sensitization.

Blood Stasis. Fixed, sharp, stabbing pain in specific locations, often worse at night. Corresponds to localized peripheral pain generators driving the central pattern.

Liver Blood and Kidney Yin Deficiency. Dry skin, brittle nails, poor sleep, anxiety, exhaustion, and pain that's worse with fatigue. Maps onto the depleted neurochemical reserves and HPA exhaustion of long-standing chronic pain.

Spleen Qi Deficiency. Heavy fatigue, post-exertional malaise, brain fog, digestive issues, and the bone-deep tiredness of fibromyalgia. Corresponds to the mitochondrial and metabolic component.

Kidney Yang Deficiency. Cold intolerance, low libido, profound fatigue, low back weakness, and chronic pain in patients with significant constitutional depletion. Maps onto long-standing HPA axis exhaustion and mitochondrial dysfunction.

Phlegm-Damp obstruction. Heaviness, swelling, brain fog, cognitive slowing, and the diffuse oppressive quality fibromyalgia patients describe. Corresponds to the neuroinflammatory component.

How We Treat Chronic Pain at GoodMedizen

At GoodMedizen, we treat musculoskeletal and chronic pain conditions using our proprietary system — Tissue Response Assessment and Corrective Strategy, or TRACS. This approach integrates the precise needling of myofascial trigger points with careful attention to timing, sequence, and the nervous system context to deliver more effective and longer-lasting results than standard acupuncture protocols alone.

For chronic pain and fibromyalgia, this matters because the peripheral pain generators — the trigger points, the fascial restrictions, the joint dysfunctions — are still feeding the central sensitization pattern even when imaging looks normal. Systematically deactivating those inputs reduces the load on a sensitized nervous system. Combined with the systemic and nervous-system-level interventions, this often produces meaningful change in patients who'd previously been told there was nothing else to try.

Alongside TRACS, we use:

Traditional acupuncture for systemic and central nervous system regulation. Acupuncture has documented effects on endogenous opioid release, serotonin and norepinephrine modulation, autonomic balance, and connectivity in pain-processing brain networks. There is substantial evidence supporting acupuncture for fibromyalgia, with multiple meta-analyses showing significant pain reduction and quality-of-life improvement.

Electroacupuncture for the muscular component, central sensitization patterns, and HPA axis regulation. Specific frequencies have specific neurochemical effects — low frequency releases endogenous opioids, higher frequencies modulate serotonin and norepinephrine.

Point Injection Therapy (PIT) is one of our most useful tools for chronic pain. Targeted injections deactivate persistent peripheral pain generators that medications and standard physical therapy can't reach. Our injectable toolkit includes:

• Procaine and Lidocaine — for trigger point deactivation; the local anesthetic effect outlasts the pharmacological half-life as the pain pattern is interrupted
• Methylcobalamin and Hydroxocobalamin (B12) — for the nerve and energy components common in chronic pain
• Homeopathic Traumeel — botanical anti-inflammatory comparable to NSAIDs for pain and swelling without the GI and cardiovascular risks
• Spascupreel — for muscle spasm and guarding
• Sarapin — FDA-approved botanical with a long history in pain medicine, useful for radicular and shooting components
• Magnesium sulfate where indicated — for the muscular and nervous system magnesium-responsive components

Peptide therapy for tissue repair and inflammation modulation in select cases. BPC-157 has emerging evidence supporting tissue repair and modulation of pain pathways.

Cupping, gua sha, and moxibustion for fascial restrictions, blood stasis patterns, and chronic muscle holding patterns.

Chinese herbal medicine tailored to the TCM pattern. Formulas to move blood, soothe the liver, tonify the spleen and kidney, or clear damp form the framework, modified for the individual presentation. Daily herbal support is often a quiet but powerful piece of chronic pain recovery.

Functional medicine assessment. We evaluate thyroid (full panel including free T3, reverse T3, antibodies), cortisol rhythm, sex hormones, vitamin D, B12 and methylation, magnesium status, omega-3 index, and inflammatory markers. We assess gut function where indicated. The findings shape the plan.

Targeted nutraceuticals with real evidence. Magnesium glycinate or threonate at therapeutic doses, malic acid, CoQ10, acetyl-L-carnitine, vitamin D3, methylated B-complex, and omega-3 fatty acids form the foundation. Low-dose naltrexone is worth discussion with patients whose chronic pain involves significant neuroinflammation — it has emerging evidence for fibromyalgia and several other chronic pain syndromes.

Nervous system regulation. Acupuncture itself does this; we also support it with breath work, vagal tone training, sleep optimization (beyond sleep hygiene platitudes), and stress regulation practices that fit your life. The goal is to move the system out of chronic threat mode — the prerequisite for pain to actually shift.

Coordination of care. Many chronic pain patients benefit from a team approach — physical therapy, trauma-informed psychotherapy (especially somatic approaches like Somatic Experiencing or EMDR), pain medicine consults where medications need adjustment, and primary care for the systemic picture. We work alongside whoever is helpful, not in opposition.
