Fibromyalgia
Widespread pain syndrome — diagnosis, management and support
Fibromyalgia is a chronic condition characterised by widespread musculoskeletal pain, fatigue, sleep disturbance, and often cognitive difficulties (sometimes called 'fibro fog'). It is a real, recognised condition — not 'all in the mind' — and affects around two million people in the UK. While it can be debilitating, effective management strategies exist.
What is Fibromyalgia?
Fibromyalgia is a central sensitisation syndrome in which the nervous system becomes hypersensitive, amplifying pain signals throughout the body. Unlike arthritis, it does not cause inflammation or damage to joints or muscles — blood tests and imaging are typically normal. The condition is characterised by widespread pain affecting multiple areas of the body, persistent fatigue that is not relieved by rest, unrefreshing sleep, cognitive symptoms such as memory and concentration difficulties, and heightened sensitivity to temperature, light, sound and touch. Fibromyalgia frequently coexists with other functional syndromes including irritable bowel syndrome, bladder pain syndrome, chronic fatigue syndrome and anxiety.
Causes & Triggers
The exact cause of fibromyalgia is not fully understood. Central sensitisation — an amplification of pain processing in the brain and spinal cord — is considered the core mechanism. Triggers for developing fibromyalgia include physical trauma or illness, psychological trauma or stress, sleep disorders, and other painful conditions. There is a genetic component, and fibromyalgia is more common in women. Importantly, fibromyalgia is not caused by psychological weakness. Factors such as poor sleep, physical deconditioning, anxiety and depression can perpetuate and worsen symptoms in a cycle that requires a comprehensive management approach to break.
Diagnosis
Fibromyalgia is diagnosed clinically based on characteristic symptoms — widespread pain lasting more than three months affecting multiple body regions, combined with fatigue, sleep disturbance and cognitive symptoms. There is no single diagnostic test. Blood tests, X-rays and other investigations are performed primarily to exclude other conditions such as inflammatory arthritis, hypothyroidism and connective tissue disease. The 2010/2016 ACR diagnostic criteria focus on symptom burden rather than tender point counts. A thorough evaluation of all symptoms, their impact on function, and associated comorbidities — particularly mood disorders and sleep disturbance — is central to making the diagnosis and formulating a treatment plan.
Management & Support
Management of fibromyalgia is multimodal and centres on self-management strategies. Graded aerobic exercise is the most evidence-based intervention — starting slowly and gradually increasing activity has been shown to reduce pain and improve quality of life. Cognitive behavioural therapy (CBT) addresses unhelpful thought patterns, catastrophising and activity avoidance. Sleep hygiene is critically important: consistent sleep and wake times, limiting daytime napping and creating a restful environment all help break the pain–poor sleep cycle. Pacing — balancing activity and rest to avoid boom-bust cycles — helps prevent flares. Medications (such as amitriptyline, duloxetine or pregabalin) can help with sleep and pain modulation when prescribed by a doctor. Fibromyalgia Action UK provides excellent peer support and resources. Seek medical review if symptoms are worsening, if you are struggling to function at work or home, or if you need help accessing specialist services.
