Understanding Chronic Pain from a Western Perspective
Chronic pain is increasingly recognised as a complex condition that extends far beyond the initial site of injury or inflammation. In modern medical understanding, pain becomes “chronic” when the nervous system continues to signal pain even after tissues have healed. This ongoing pain is not simply a symptom but a condition involving dynamic interactions between the nerves, immune system, and brain.
When the body experiences injury, immune cells release inflammatory molecules to promote healing. In some cases, this inflammation becomes persistent, sensitising nerve endings and altering pain-processing pathways in the spinal cord and brain—a process known as central sensitisation. Over time, the nervous system becomes “trained” to overreact to normal sensations, amplifying pain even in the absence of new damage.
Research in neuroscience and immunology has revealed that glial cells, which support and protect neurons, also play a role in chronic pain by releasing pro-inflammatory cytokines that perpetuate nerve hypersensitivity. Similarly, stress and emotional factors can heighten pain perception through dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, which influences immune and hormonal balance. This interconnected system explains why chronic pain often coexists with fatigue, anxiety, and poor sleep.
At North Shore Health, our approach to chronic pain integrates these modern insights with the wisdom of Traditional Chinese Medicine (TCM) to create comprehensive, restorative care that addresses both the biological and energetic aspects of pain.
Acupuncture and the Neuro-Immune Connection
From a Western perspective, acupuncture influences pain through measurable physiological effects. Studies have shown that needling specific points activates afferent nerve fibres, which then modulate pain processing in the spinal cord and brain. This stimulation triggers the release of endorphins, enkephalins, and serotonin—the body’s natural pain-relieving and mood-stabilising chemicals.
A 2020 review in The Journal of Pain concluded that acupuncture reduces chronic pain by regulating both the central nervous system and immune pathways, particularly by suppressing pro-inflammatory cytokines and promoting anti-inflammatory mediators. These effects can help desensitise overactive nerve pathways, reduce inflammation, and restore balance in the neuro-immune network.
In Traditional Chinese Medicine, chronic pain is understood as the result of stagnation—whether of qi (energy), blood, or internal fluids. Acupuncture seeks to restore flow, harmonise the body’s internal environment, and allow natural healing processes to resume. Practically, this corresponds to improving circulation, reducing muscular tension, and calming the stress response that often perpetuates chronic pain.
At North Shore Health, our practitioners often use acupuncture for chronic pain conditions such as fibromyalgia, neuropathic pain, and musculoskeletal tension. Gentle electrical stimulation enhances the effects of traditional acupuncture, improving nerve conduction and increasing local blood flow for accelerated healing.
The Role of Herbal Medicine in Pain Modulation and Healing
While acupuncture works through immediate physiological signalling, Chinese herbal medicine provides a longer-term regulatory effect by addressing the internal imbalances that sustain chronic pain. Herbs are chosen not only for symptom relief but to support immune regulation, circulation, and energy metabolism—core systems involved in the pain process.
For example:
-
Corydalis (Yan Hu Suo) is known for its potent analgesic properties, acting on dopamine and opioid receptors to relieve pain without dependency.
-
Turmeric (Jiang Huang) and Peony root (Bai Shao) are anti-inflammatory and support smooth muscle relaxation and microcirculation.
-
Angelica sinensis (Dang Gui) nourishes blood and promotes healing in cases of deficiency or menstrual-related pain.
Modern pharmacological research has validated many of these traditional uses. A 2023 systematic review in Frontiers in Pharmacology reported that herbal formulations used in TCM modulate inflammatory cytokines, regulate immune cell activity, and influence the gut–brain axis—an emerging focus in chronic pain management.
At North Shore Health, we tailor herbal prescriptions based on each individual’s pattern presentation—whether it involves inflammation, deficiency, stagnation, or nervous system overactivation. This personalised approach ensures that herbal therapy complements acupuncture and physiotherapy, supporting the body’s self-healing mechanisms on multiple levels.
Integrative Pain Management at North Shore Health
Our integrative care model for chronic pain combines acupuncture, herbal medicine, and physiotherapy to address pain from both the structural and systemic perspectives.
-
Acupuncture targets nerve pathways, reduces inflammation, and calms the stress response.
-
Herbal medicine nourishes and regulates the internal environment for long-term recovery.
-
Physiotherapy restores movement, alignment, and strength, preventing recurrence.
Treatment plans are personalised to the nature and duration of the pain, as well as the underlying physical and emotional contributors. Many patients experience meaningful relief within several weeks, along with improved sleep, mood, and energy.
Our goal is not only to reduce pain but to restore resilience—helping the nervous system relearn balance and calm after prolonged stress or injury.
Personalised Healing at North Shore Health
At North Shore Health, we recognise that chronic pain is deeply personal and multifactorial. Our integrative approach combines evidence-based medicine with the holistic principles of Traditional Chinese Medicine to create truly comprehensive care.
If you are living with persistent pain, fatigue, or inflammation, we invite you to speak with one of our experienced practitioners. Together, we can design a program that combines acupuncture, herbal therapy, and gentle movement to help your body recover, rebalance, and thrive.
