Fibromyalgia is a chronic condition characterised by widespread musculoskeletal pain, fatigue, sleep disturbance, and cognitive difficulties. It is classified as a central sensitisation syndrome, meaning the nervous system amplifies pain signals, making ordinary sensations painful and painful sensations excruciating.
Fibromyalgia affects approximately 2-4% of the population and is significantly more common in women. It was officially recognised by the American College of Rheumatology in 1990 and has clear diagnostic criteria. It is not "just stress" or "all in your head" - measurable neurobiological abnormalities are consistently found on functional imaging.
A fibromyalgia diagnosis requires: widespread pain index (WPI) of 7 or more with symptom severity score (SSS) of 5 or more, OR WPI of 4-6 with SSS of 9 or more. Symptoms present for at least 3 months. Pain cannot be better explained by another diagnosis.
Fibromyalgia rarely presents alone. Common co-occurring conditions: Central Sensitisation Syndrome (80%+ overlap), IBS (40-70%), chronic fatigue/ME-CFS (overlap), depression and anxiety (30-50%), migraine (50%), PTSD (elevated), lupus and rheumatoid arthritis (secondary fibromyalgia), interstitial cystitis, and temporomandibular joint disorders (TMJ).
Fibromyalgia symptoms wax and wane. Flares are periods of intensified symptoms triggered by physical or emotional stress, illness, poor sleep, weather changes, or overexertion. Understanding and managing flare triggers is central to living well with fibromyalgia.

Fibromyalgia is now understood as a disorder of central pain processing. The brain and spinal cord become sensitised, amplifying pain signals throughout the body.
Central Sensitisation
The central nervous system becomes hypersensitised, amplifying pain signals from the periphery. Wind-up and long-term potentiation of spinal neurons creates persistent pain without tissue damage.
Altered Neurotransmitters
Reduced serotonin, norepinephrine, and dopamine in descending pain inhibitory pathways. Elevated substance P and glutamate amplify pain transmission in the spinal cord.
HPA Axis Dysregulation
Abnormal hypothalamic-pituitary-adrenal axis function results in dysregulated cortisol, altered stress response, and impaired pain modulation.
Sleep Architecture Disruption
Alpha wave intrusion into deep (delta) sleep prevents restorative sleep. Poor sleep worsens pain sensitivity, creating a vicious cycle of pain and sleeplessness.
Small Fibre Neuropathy
Recent research identifies reduced small fibre density in fibromyalgia patients - a measurable peripheral abnormality that may drive central sensitisation.
Neuroinflammation
PET imaging studies show glial activation and neuroinflammation in pain-processing brain regions including the thalamus and anterior cingulate cortex.
Fibromyalgia is a systemic condition affecting multiple interconnected biological systems. Understanding these systems helps identify targeted interventions.
1. Central Nervous System
Persistent background activity keeps the network in a high-idle state, causing cognitive fatigue (fibro fog). The brain's pain processing centres remain in a state of constant hyper-alert.
2. Digestive System
Microbiome and gut-brain axis imbalances disrupt systemic regulation and inflammatory markers. IBS overlap is extremely common (40-70%).
3. Endocrine System
Chronic hormonal imbalance keeps the body in a permanent survival loop. HPA axis dysregulation affects cortisol, thyroid function, and metabolic regulation.
4. Autonomic Nervous System
The brake on your pain signaling pathway fails to engage, leaving you stuck in high-alert. Dysautonomia affects heart rate, blood pressure, and digestion.
5. Cognitive & Emotional Systems
Social and emotional processing centres remain in a state of continuous hyper-arousal, treating normal input as a threat. Anxiety and depression commonly co-occur.
6. Musculoskeletal System
Peripheral tissues become hyper-responsive to stimuli, leading to heightened pain perception. Tender points reflect systemic hypersensitivity, not local damage.
7. Immune System
Inflammatory signaling pathways remain chronically active, lowering the threshold for pain activation. Neuroimmune dysfunction is a key research area.
8. Sleep System
Dysregulation of circadian rhythms and restorative cycles limits your capacity to recover from physical stress. Alpha wave intrusion prevents deep sleep.
Fixing these systemic issues requires shifting from symptom management to systemic regulation. By introducing targeted sensory inputs, structured pacing, nutritional support, and management techniques, you can influence the feedback loops governing your biological state.
Standard blood tests, X-rays, and MRI scans are typically normal in fibromyalgia because the pathology is in pain processing circuitry, not in tissue damage. This does not mean the pain is not real. Functional MRI studies consistently show abnormal brain activation patterns. The absence of structural pathology is expected, not evidence against the diagnosis.
The FIQ-R measures the impact of fibromyalgia on your functioning and quality of life. Rate each item 0-10 where 0 = never/no difficulty and 10 = always/extreme difficulty. Not a diagnostic tool.

8. Energy level (fatigue)
9. Stiffness
10. Sleep quality
In fibromyalgia, these 8 brain regions become dysregulated - creating the pain amplification, fatigue, and fog that define the condition.
1. Thalamus - The Filter 📡
Excess glutamate makes this "air traffic controller" leaky, amplifying ordinary sensory data into high-voltage pain signals.
💡 Grounding: Practice naming 5 non-painful sensations you feel. This re-tunes the filter to non-painful stimuli and lowers neural noise.
2. Prefrontal Cortex - The CEO 🏗️
Overloaded hardware impairs your ability to "shut down" pain signals. The CEO loses the energy to send inhibitory signals down the spinal cord.
💡 Cognitive Restructuring: Use CBT to modify "pain catastrophizing" thoughts. This manually overrides the hardware and forces the CEO back into logic mode.
3. Anterior Cingulate - The Emotion ⚙️
Reduced connectivity here means the brain cannot distinguish between a physical injury and a stress signal, giving pain its emotional "misery" tone.
💡 Cognitive Defusion (ACT): Practice observing your thoughts as external data. This reduces the emotional weight the ACC adds to pain signals.
4. Insula - The Volume 🔊
The Insula is hyper-responsive to touch and light, often leading to Allodynia - where normal touch feels painful.
💡 Somatic Acceptance: Instead of fighting the sensation, practice mindful "dropping in" to the feeling without judgment. This tells the Insula the threat is not an emergency.
5. Default Mode Network - The Static 📻
This network stays chronically active during tasks, causing "quasi-sleep" cognitive fatigue and constant pain focus.
💡 Task Bracketing: State your start and end times out loud. This auditory cue helps force the DMN to yield to the "Task Positive" network.
6. Hypothalamus - The Stress 🌡️
Fibromyalgia brains can secrete twice the normal amount of stress hormones like CRH, keeping the system in permanent survival mode.
💡 Physiological Sigh: Take a double inhale through the nose followed by a long exhale. This immediately signals the Hypothalamus to downregulate the stress pulse.
7. Amygdala - The Alarm 🚨
Chronic self-reproach over physical limitations keeps the Amygdala in a state of hyper-arousal, treating pain as a literal attack.
💡 Biological De-escalation: Use rhythmic breathing to engage the Vagus nerve and lower the "alarm" signal to create safety for recovery.
8. Brainstem - The Brake ⚡
The brainstem should act as a "lid" on pain, but in Fibromyalgia this descending inhibition is a whisper instead of a shout.
💡 Pacing: Use a biopsychosocial approach to activity. Gradually increase movement in a way that does not trigger a flare to help the brainstem re-learn how to inhibit pain.
Evidence grades: A Strong · B Moderate · C Emerging · D Limited
| Treatment | Evidence | Notes |
|---|---|---|
| Aerobic Exercise | A | Most consistently evidence-backed treatment for fibromyalgia. Low-impact (walking, swimming, cycling). Must be graded carefully to avoid flares. Reduces pain, fatigue, and depression long-term. |
| Duloxetine (Cymbalta) | A | SNRI FDA-approved for fibromyalgia. Increases serotonin and norepinephrine, enhancing descending pain inhibition. 30-60mg. Effective for pain and mood comorbidity. |
| Pregabalin (Lyrica) | A | FDA-approved for fibromyalgia. Reduces neuronal excitability by blocking calcium channels. Effective for pain and sleep. Side effects include weight gain and sedation. |
| Milnacipran (Savella) | A | SNRI FDA-approved specifically for fibromyalgia. Stronger norepinephrine effect than duloxetine. Effective for pain and fatigue. |
| CBT (pain-focused) | A | Pain-focused cognitive behavioural therapy reduces catastrophising, improves coping, and decreases pain interference. Best combined with physical therapy. |
| Low Dose Naltrexone (LDN) | B | 1.5-4.5mg nightly. Anti-neuroinflammatory via glial modulation. Multiple trials showing 30% pain reduction. Well-tolerated, off-label, growing evidence base. |
| Amitriptyline (low dose) | B | 10-50mg at night. Improves sleep architecture and reduces pain. First-line in many guidelines despite being off-label. Effective for sleep and morning stiffness. |
| Mindfulness / MBSR | B | Mindfulness-Based Stress Reduction reduces pain catastrophising, improves wellbeing, and complements pharmacological treatment. |
| Hydrotherapy / Aquatic Exercise | B | Warm water reduces pain and resistance, enabling exercise with less discomfort. Consistently beneficial in RCTs for fibromyalgia. |
| Gabapentin | B | Related to pregabalin. Reduces central sensitisation. Off-label for fibromyalgia with reasonable evidence. Less studied than pregabalin. |
| Magnesium supplementation | C | Magnesium deficiency is common in fibromyalgia. Supplementation (malate form preferred) may reduce pain and fatigue in deficient patients. |
| Opioids | D | Not recommended for fibromyalgia. Central sensitisation means opioids may worsen pain long-term via opioid-induced hyperalgesia. Most guidelines advise against. |
Pacing Activity
Avoid the boom-bust cycle: overdoing on good days and crashing for days after. Plan consistent, moderate activity regardless of how you feel. Rest before you need to.
Sleep Hygiene
Consistent bedtime and wake time are critical. Alpha-wave intrusion disrupts restorative sleep. Amitriptyline, melatonin, and CBT-I can all improve sleep quality. Avoid screens before bed.
Pain Management
Heat therapy, warm baths, and TENS units provide symptomatic relief. Gentle stretching and yoga reduce stiffness. Cognitive reframing reduces pain catastrophising significantly.
Nutrition
Anti-inflammatory diet reduces inflammatory load. Reducing sugar, processed foods, and gluten (in sensitive individuals) can reduce flare frequency. Magnesium-rich foods support muscle function.
Flare Management
Identify your flare triggers: physical overexertion, emotional stress, illness, weather changes. Keep a symptom diary. During flares: rest, warmth, gentle movement, and avoid pushing through.
Mental Health
Depression and anxiety are common comorbidities, not just reactions to pain. Treat them as separate conditions alongside fibromyalgia. Peer support groups and therapy are highly effective.
Fibromyalgia is typically managed by rheumatologists, pain specialists, or neurologists. GPs can initiate treatment. A multidisciplinary team (rheumatology, pain psychology, physiotherapy) gives best outcomes.
