Fibromyalgia: symptoms, diagnosis and what helps

In short

• Fibromyalgia causes widespread pain, deep tiredness and poor sleep. Many people also notice memory and concentration problems, often called fibro fog.
• It is more common in women and usually shows up in middle age, though anyone can develop it.
• There is no single test. A clinician listens to your history, examines you and sometimes orders blood tests or scans to rule out other causes.
• Treatment is a mix of gradual exercise, sleep and stress habits, talking therapy such as CBT, and sometimes medicines prescribed by a doctor.
• See a clinician if pain and fatigue last for weeks. Call 911 for chest pain, trouble breathing, sudden weakness on one side or thoughts of self-harm.

What fibromyalgia is and who gets it

Fibromyalgia is a long-lasting condition that causes widespread muscle pain, fatigue and other symptoms. Doctors think the nervous system becomes more sensitive and amplifies pain signals, which is why the pain can feel out of proportion to anything a scan can show.

Anyone can develop it, but it is more common in women, who are about twice as likely to have it, and in middle-aged adults. The NHS says it usually develops between ages 25 and 55 and that nearly 1 in 20 people may be affected to some degree, although the true number is unclear.

It is also more common in people with lupus, rheumatoid arthritis, osteoarthritis or ankylosing spondylitis, and in people with a relative who has it. It can sit alongside these conditions rather than replace them.

Symptoms: what is typical

• Pain and stiffness across much of the body, often described as aching, burning or throbbing.
• Fatigue and unrestful sleep, even after a full night in bed.
• Memory and concentration trouble, the fibro fog.
• Headaches or migraines, jaw and face pain, digestive problems such as irritable bowel syndrome, numbness or tingling in the limbs.
• Sensitivity to light, noise, smells and temperature, plus anxiety, low mood or depression in many people.

Symptoms come and go. Flare-ups can follow emotional stress, a change in routine, poor sleep, weather or temperature changes, an illness or injury, or starting or changing a medicine.

Visibly swollen joints are not part of the picture. They point your clinician toward another condition such as arthritis, which is why a physical exam matters.

Causes and risk factors

The exact cause is unknown. Brain studies suggest that people with fibromyalgia process pain differently and may react more strongly to it. Genes seem to play a part because it can run in families. Triggers such as an injury, an infection or stress may set it off in someone who is already vulnerable.

Other chronic pain disorders, mood disorders and significant stress raise the risk. None of these is a fault of yours, and nothing you did or did not do explains the condition.

What you can do day to day

1. Start gently.Regular exercise is among the most useful approaches, and even modest amounts help. Start low and increase gradually, with walking, biking, swimming, water exercise, yoga or tai chi. Check with your doctor first, and ask about a physical therapist if you need a plan.
2. Protect your sleep.Keep a consistent bedtime and wake time, use the bed for sleep only, keep the bedroom dark, quiet and cool, avoid caffeine and nicotine, limit alcohol, and wind down before bed.
3. Pace yourself.Do not spend all your energy on a good day. Overdoing it can worsen symptoms, so balance activity with rest.
4. Look after your mood.Learn about the condition, consider a support group, and see a mental health professional if emotional problems build up.
5. Note your triggers.A simple diary of sleep, stress and activity can show what tends to set off a flare, which gives your clinician something concrete to work with.

When to see a doctor

• Pain, fatigue or poor sleep have lasted for weeks and are affecting work, home life or mood.
• You are struggling physically or emotionally, or you notice a change in mood or persistent brain fog.
• Symptoms are not improving even though you take your medicines as prescribed.
• You develop swollen joints or other new symptoms that fibromyalgia does not explain.

Start with your primary care provider. Treatment is mainly led by primary care providers and rheumatologists, and a team may also include a physical therapist, a mental health professional, a pain specialist or a sleep specialist.

Red flags, call 911 now: chest pain or pressure; trouble breathing; sudden weakness, numbness or drooping on one side of the body; sudden confusion or trouble speaking; fainting. These are not signs of fibromyalgia. If you are thinking of harming yourself, call 911 or call or text 988.

How a doctor makes the diagnosis

There are no specific laboratory or imaging tests for fibromyalgia. Your clinician asks where the pain is, how severe it is, how long it has lasted, how tired you are and whether you have thinking problems or other conditions, then examines your joints.

Blood and urine tests, and sometimes X-rays or other scans, are used to look for other causes such as thyroid disease or inflammatory arthritis. A normal result does not mean your symptoms are imaginary. It means the explanation lies elsewhere.

Clinicians often follow American College of Rheumatology criteria: widespread pain in at least four of five body regions, symptoms lasting at least three months, and no other condition that fully explains the pain. You can have fibromyalgia together with depression, anxiety or irritable bowel syndrome, and further tests may be needed for those.

Treatment options in general terms

Treatment aims to ease symptoms and improve quality of life, and no single option works for everyone. Most plans combine exercise, psychological therapy and, when needed, medicines.

• Exercise programs, alone or in a group, reduce pain and improve quality of life, especially when you pick something you enjoy and can keep up.
• Talking therapies: cognitive behavioral therapy changes how you think and behave around long-term pain, and acceptance and commitment therapy helps you accept what you cannot control. ACT has been shown to improve sleep quality and reduce pain.
• Medicines: certain antidepressants and anti-seizure medicines may reduce pain or improve sleep, and pain relievers are sometimes added. Anti-inflammatory painkillers are usually not effective here because fibromyalgia does not cause tissue inflammation.
• Acupuncture may reduce pain for some people, though benefits have only been shown to last up to 3 months.
• Massage, yoga, tai chi, mindfulness and biofeedback are used too, but more research is needed.

All medicines are used only as prescribed by a doctor, who should explain benefits and downsides and review everything else you take. Finding the right combination often takes time and improvement is gradual. There is little or no evidence that other types of medicine help long-term pain, so ask before adding anything on your own.

Myths and facts

• Myth: the tests are normal, so it is nothing. Fact: normal tests are expected, and the diagnosis is made from your symptoms.
• Myth: you should rest until it passes. Fact: gentle, gradual activity is one of the best-supported steps.
• Myth: it is the same as arthritis. Fact: the two can coexist, but fibromyalgia does not cause joint swelling or tissue inflammation.
