Key facts

Fibromyalgia at a glance.

The essentials, in plain English: what it is, how it is diagnosed, and how modern UK care is built.

  • What it is

    A chronic disorder of widespread pain with fatigue, non-restorative sleep and cognitive symptoms, driven by altered central pain processing (nociplastic pain, per IASP).

  • How common

    Around 2 to 4 percent of UK adults. Women are affected 3 to 5 times more often than men, with a peak in the 30s to 60s.

  • Underlying mechanism

    Central sensitisation, not tissue damage. The nervous system amplifies and misinterprets normal signals as pain.

  • How it is diagnosed

    ACR 2016 criteria: Widespread Pain Index (WPI) plus Symptom Severity Scale (SS), with symptoms present for more than three months.

  • Foundation of care

    Education, graded exercise and psychological therapy carry the strongest evidence. Medicines play a supporting role.

  • What to avoid

    Opioids are harmful in fibromyalgia and benzodiazepines rarely help. UK guidance is clear on both.

Why this guide matters

A modern understanding, with a workable plan.

Fibromyalgia is now understood as a nociplastic pain disorder. That single idea reframes what helps and what does not.

  • It is a real, mechanism-based condition

    Central sensitisation and altered pain processing are measurable. The pain is not imagined and not a marker of weakness.

  • Non-drug care carries the strongest evidence

    Education, graded exercise and psychological therapy consistently outperform medicines in trials and guidelines.

  • Comorbidities shape the whole picture

    IBS, migraine, POTS, hypermobility, sleep apnoea and mood disorders often coexist. Treating them well helps the pain too.

How the diagnosis is made

From first symptoms to a clear plan.

The steps a UK GP, rheumatologist or pain specialist will normally follow, in order, so you know what to expect.

  1. 01

    Assessing

    Structured pain history

    A pain diary, functional impact and screening for coexisting conditions such as CFS/ME, IBS, migraine, POTS and hypermobility.

  2. 02

    Assessing

    Widespread Pain Index and SS

    ACR 2016: WPI of 7 or more plus SS of 5 or more, or WPI 4 to 6 with SS of 9 or more, for at least three months.

  3. 03

    Assessing

    Clinical examination

    A careful musculoskeletal and neurological review to rule out inflammatory arthritis, myopathy and neurological mimics.

  4. 04

    Confirming

    Baseline bloods

    FBC, CRP, ESR, TFTs, vitamin D, ferritin, CK, LFTs and a rheumatology screen (RF, anti-CCP, ANA) to exclude alternative diagnoses.

  5. 05

    Confirming

    Selective further tests

    Sleep study if obstructive sleep apnoea is suspected. Additional tests only when history or examination points that way.

  6. 06

    Planning

    Rheumatology or pain medicine

    Specialist input for uncertain diagnoses, refractory symptoms or when a specialist commissioned pain service is needed.

  7. 07

    Planning

    Multidisciplinary plan

    A tailored plan across education, exercise, psychology, sleep and, where useful, medication.

Typical timeline: weeks to a working plan, not months of unanswered questions.

Symptoms

What fibromyalgia actually feels like.

Widespread pain sits at the centre, with fatigue, unrefreshing sleep, cognitive symptoms and sensory sensitivity woven through it.

  • Widespread pain

    Pain on both sides of the body, above and below the waist, plus axial pain, present for more than three months.

  • Persistent fatigue

    A deep, unrefreshing tiredness that is not fixed by rest and often overlaps with CFS/ME.

  • Non-restorative sleep

    Waking unrefreshed despite adequate hours, with frequent night waking and light sleep.

  • Fibro fog

    Slower thinking, word-finding difficulty and problems with concentration and short-term memory.

  • Morning stiffness

    Generalised stiffness on waking that eases with gentle movement, without joint swelling.

  • Sensory sensitivity

    Heightened sensitivity to light, noise, smells, temperature and touch, often with headaches and jaw pain.

  • Autonomic and gut symptoms

    Dizziness, palpitations, IBS-like symptoms, bladder urgency and features overlapping with POTS and dysautonomia.

  • Red flag features

    Unexplained weight loss, fevers, joint swelling or new neurological signs point to another diagnosis and need urgent review.

Treatment

How fibromyalgia is treated in the UK.

NICE NG193, EULAR and BSR guidance point in the same direction: education and movement first, targeted medicines and multidisciplinary care next.

  • Education and self-management

    Understanding central sensitisation and nociplastic pain is the single most important step. It shapes every choice that follows.

  • Graded aerobic exercise

    Slow, steady increases in walking, cycling or swimming. Little and often, with pacing, beats occasional heavy sessions.

  • Strength and movement

    Resistance work, tai chi and yoga all have evidence in fibromyalgia. Supervised hypermobility physiotherapy helps when EDS coexists.

  • Psychological therapy

    CBT and Acceptance and Commitment Therapy (ACT) reduce distress and disability. Mindfulness-based stress reduction is a useful adjunct.

  • Sleep support

    CBT for insomnia (CBT-I), sleep hygiene and treatment of any obstructive sleep apnoea. Restoring sleep improves pain and cognition.

  • Amitriptyline or duloxetine

    Low-dose amitriptyline at night or duloxetine (Cymbalta) can help pain and sleep in selected patients, under regular review.

  • Pregabalin or gabapentin

    A specialist-led option when pain and sleep remain limiting after first-line measures, with careful monitoring for side effects.

  • Multidisciplinary pain programme

    Specialist commissioned pain services combine physiotherapy, psychology and medical review. The best-evidenced route for complex cases.

Red flags

When fibromyalgia needs a closer look.

Most people with fibromyalgia are safely managed in primary care. These features suggest another diagnosis, or a specialist opinion, is needed.

  • New joint swelling or synovitis

    Fibromyalgia does not cause visible joint swelling. New swelling suggests inflammatory arthritis and needs rheumatology review.

  • Fevers, weight loss or night sweats

    Systemic features are not part of fibromyalgia. They point to infection, malignancy or connective tissue disease and need urgent assessment.

  • New neurological signs

    Focal weakness, sensory loss, bladder or bowel disturbance, or new severe headache need same-day medical review.

  • Severe or worsening low mood

    Fibromyalgia frequently coexists with depression and anxiety. Suicidal thoughts need urgent GP or crisis-team support.

  • Escalating opioid use

    Opioids worsen outcomes in fibromyalgia. Rising doses or dependence need specialist-led review and a deprescribing plan.

  • Suspected obstructive sleep apnoea

    Loud snoring, witnessed apnoeas and daytime sleepiness deserve a sleep study. Treating OSA transforms fatigue and cognition.

  • Suspected inflammatory rheumatic disease

    Prolonged morning stiffness with swelling, rash or Raynaud phenomenon warrants a rheumatology opinion.

  • Coexisting POTS or dysautonomia

    Persistent postural dizziness, palpitations or fainting should be assessed with lying and standing observations and, where needed, cardiology input.

  • New severe headache pattern

    A change in headache frequency, character or associated features needs review, especially if new after age 50.

Living with it

A treatable condition, one steady day at a time.

Four things that make the biggest difference day to day: pacing, gentle movement, protected sleep and knowing where to turn for support.

A quiet reminder

Consistency beats intensity, every time.

Small, steady habits, kept up for months, do more than a heroic week that leaves you flat for a fortnight.

  1. 01 Pacing

    Little and often

    Break activity into short blocks with planned rest. Consistency day to day matters more than any single big effort.

  2. 02 Movement

    Move gently, most days

    Aerobic exercise is one of the strongest evidence-based tools. Start below what you think you can do and build slowly.

  3. 03 Sleep

    Protect the sleep window

    A regular wake time, low evening light and treating any sleep apnoea often ease pain, fog and fatigue together.

  4. 04 Support

    You are not alone

    Fibromyalgia Action UK, Versus Arthritis and specialist pain services offer information, community and structured programmes.

Frequently asked

Everything we get asked about fibromyalgia.

Quick answers on diagnosis, treatment, overlap with CFS/ME, and why opioids are best avoided.

  • What is fibromyalgia?

    Fibromyalgia is a chronic condition of widespread pain, fatigue, non-restorative sleep and cognitive symptoms. It is classed as nociplastic pain by the IASP, meaning the pain arises from altered processing in the nervous system rather than ongoing tissue damage.

  • How is it diagnosed?

    The ACR 2016 criteria use the Widespread Pain Index and Symptom Severity Scale, with symptoms present for more than three months. Blood tests and a careful examination help rule out inflammatory arthritis, thyroid disease, low vitamin D and other mimics. There is no single blood test that confirms fibromyalgia.

  • Is fibromyalgia the same as chronic fatigue syndrome?

    They overlap but are not identical. Many people meet criteria for both. Fibromyalgia is defined by widespread pain plus core symptoms, while CFS/ME (see our chronic fatigue syndrome guide) centres on post-exertional malaise and profound fatigue. Assessment and management share many principles.

  • What actually helps?

    The strongest evidence sits with education about central sensitisation, graded aerobic exercise, strength work, tai chi or yoga, and psychological therapies such as CBT and ACT. Sleep support with CBT-I is often transformative. Medications such as low-dose amitriptyline, duloxetine or pregabalin help some people as part of a wider plan.

  • Why should opioids be avoided?

    UK and international guidance is consistent: opioids do not improve long-term outcomes in fibromyalgia and can worsen pain, sleep and function while causing dependence. Benzodiazepines are also generally unhelpful. A structured deprescribing plan with your GP or a pain specialist is usually the safest route.

  • Can fibromyalgia get better?

    Symptoms fluctuate and, with the right plan, many people regain a good quality of life. Full remission is possible for some, and meaningful improvement is realistic for most, especially when coexisting sleep, mood, IBS and hypermobility issues are addressed alongside the pain itself.
