Fibromyalgia: Understanding and Managing Widespread Chronic Pain
An evidence-based guide to fibromyalgia, its symptoms, diagnosis, and the multimodal treatment approach used at Cygnet Clinic, Fremantle.
What Is Fibromyalgia?
Fibromyalgia is a chronic pain condition characterised by widespread, bilateral pain affecting the muscles, soft tissues, and joints above and below the waist, persisting for more than three months. It is classified as a central sensitisation syndrome, meaning the nervous system becomes amplified in its processing of pain signals, causing normally non-painful stimuli to be experienced as painful.
Fibromyalgia affects approximately 2 to 5 per cent of the population, with women being more commonly diagnosed than men. It frequently coexists with other conditions such as irritable bowel syndrome, chronic fatigue syndrome, migraines, anxiety, and depression.
Common Symptoms of Fibromyalgia
Fibromyalgia is a multisystem condition. While widespread pain is the hallmark symptom, patients typically experience a cluster of associated symptoms:
- Widespread pain: A deep, aching, or burning pain affecting both sides of the body, above and below the waist, and including the axial skeleton (neck and back).
- Fatigue: Profound, unrefreshing tiredness that is not relieved by rest or sleep.
- Sleep disturbance: Difficulty falling asleep, frequent waking, and non-restorative sleep patterns.
- Cognitive difficulties (fibro fog): Problems with concentration, memory, and mental clarity.
- Heightened sensitivity: Allodynia (pain from non-painful stimuli) and hyperalgesia (amplified pain responses).
- Morning stiffness: Particularly in the hands, feet, and spine.
- Headaches and migraines: Frequently coexisting with fibromyalgia.
- Mood disturbances: Anxiety and depression are common.
How Is Fibromyalgia Diagnosed?
There is no single blood test or scan that diagnoses fibromyalgia. Diagnosis is clinical, based on a thorough history and examination. Dr Agrawal will assess the pattern and duration of your pain, associated symptoms, sleep quality, and impact on daily function. Blood tests may be ordered to exclude other conditions (such as inflammatory arthritis, thyroid dysfunction, or vitamin deficiencies) that can mimic fibromyalgia symptoms.
The key diagnostic criteria include:
- Widespread pain on both sides of the body, above and below the waist, for at least three months
- The presence of associated symptoms such as fatigue, sleep disturbance, and cognitive difficulties
- Exclusion of other conditions that could fully explain the symptoms
Understanding Central Sensitisation
A core concept in understanding fibromyalgia is central sensitisation. In a healthy nervous system, pain signals are transmitted from the site of injury to the brain, where they are processed and perceived. In fibromyalgia, the central nervous system (brain and spinal cord) becomes sensitised, amplifying pain signals and lowering the threshold for pain perception. This means that signals that would normally be experienced as touch or pressure are perceived as painful.
This understanding is important because it means that treatments targeting only the peripheral tissues (such as joint injections alone) are often insufficient. Effective management must also address the central nervous system through medication, psychological strategies, sleep optimisation, and graded activity.
Evidence-Based Treatment Approach
Fibromyalgia requires a multimodal, multidisciplinary approach. No single treatment is effective on its own. Dr Agrawal coordinates care across several domains:
1. Medication Optimisation
- Neuromodulatory medications: Pregabalin, gabapentin, and duloxetine have evidence for reducing fibromyalgia pain and improving sleep.
- Low-dose antidepressants: Amitriptyline or nortriptyline, taken at night, can improve sleep quality and reduce pain.
- Pain management: Paracetamol and certain anti-inflammatories may provide partial relief. Opioids are generally not recommended for fibromyalgia.
2. Physical Rehabilitation
- Graded exercise: Gradually increasing aerobic exercise (walking, swimming, cycling) is one of the most evidence-based treatments for fibromyalgia. Starting slowly and building gradually is key, as sudden increases in activity can trigger flare-ups.
- Physiotherapy: Tailored programs to improve strength, flexibility, and posture without overexertion.
- Pacing: Learning to balance activity and rest to avoid the boom-and-bust cycle that is common in fibromyalgia.
3. Psychological Support
- Cognitive behavioural therapy (CBT): Helps identify and change unhelpful thought patterns about pain, improve coping strategies, and reduce the impact of pain on mood and function.
- Acceptance and commitment therapy (ACT): Focuses on accepting what cannot be changed (chronic pain) while committing to actions that align with personal values.
- Mindfulness-based strategies: Meditation, relaxation techniques, and breathing exercises to reduce the stress response that amplifies pain.
4. Sleep Optimisation
- Sleep hygiene education
- Treatment of coexisting sleep disorders (such as sleep apnoea or restless legs syndrome)
- Cognitive behavioural therapy for insomnia (CBT-I)
5. Interventional Procedures
While fibromyalgia is primarily a central pain condition, many patients also have superimposed peripheral pain generators (such as osteoarthritic joints, trigger points, or nerve entrapments). Targeted injections or nerve blocks for these specific pain sources can reduce the overall pain burden and make the central sensitisation more manageable.
Living Well with Fibromyalgia
Fibromyalgia is a chronic condition, but it is not progressive or life-threatening. With the right combination of treatments, most patients can achieve meaningful improvements in pain, function, and quality of life. The goals of treatment are realistic: not to eliminate pain entirely, but to reduce its intensity, improve sleep and energy, and restore the ability to participate in the activities that matter to you.
If you suspect you may have fibromyalgia, ask your GP for a referral to Dr Ravi Agrawal at Cygnet Clinic, 109 Marine Terrace, Fremantle WA 6160.
