Fibromyalgia

Medically reviewed by the Florence Healthcare medical teamLast updated July 2026

Fibromyalgia is a long-term condition that causes widespread body pain, extreme tiredness, poor sleep, and problems with memory and concentration ("fibro fog"). Its exact cause is not fully understood but is thought to involve how the nervous system processes pain. It is real, common, and can be managed.

Overview

What is fibromyalgia?

Fibromyalgia is a long-term (chronic) condition that causes pain felt across many parts of the body, along with tiredness and other symptoms. Rather than coming from damage or inflammation in the joints or muscles themselves, the pain is linked to changes in the way the nervous system processes and amplifies pain signals.

It is common and can affect anyone, though it is diagnosed more often in women and often begins in middle adulthood. Symptoms can vary from day to day, with better spells and flare-ups.

Is fibromyalgia a real condition?

Yes. Fibromyalgia is a recognized medical condition, and the pain and fatigue people describe are genuine. It is not imagined and it is not a sign of weakness. Because routine blood tests and scans usually look normal, it can take time to be diagnosed, which many people find frustrating — but a normal test result does not mean nothing is wrong.

Symptoms & causes

What are the symptoms?

The main symptom is widespread pain that may feel like an ache, burning, or sharpness and can move around the body. Many people also have marked fatigue, sleep that does not feel refreshing, and stiffness — especially after resting.

"Fibro fog" describes problems with memory, concentration, and word-finding. Headaches, irritable bowel symptoms, heightened sensitivity to pain, temperature, or noise, and low mood or anxiety are also common.

What causes fibromyalgia?

The exact cause is not fully understood. Current thinking is that the nervous system becomes more sensitive to pain, so signals that would not normally hurt are felt as painful or are amplified. Differences in sleep, stress responses, and how pain is processed in the brain and spinal cord appear to play a part.

Symptoms sometimes begin after a trigger such as a physical injury, an infection, or a period of significant emotional stress, though for many people there is no single clear cause. It can also run in families.

Diagnosis

How is fibromyalgia diagnosed?

There is no single blood test or scan that confirms fibromyalgia. It is a clinical diagnosis, based on your pattern of symptoms — particularly widespread pain lasting several months together with fatigue and sleep or cognitive problems — and a physical examination.

Doctors usually arrange some tests, such as blood tests, to rule out other conditions that can cause similar symptoms, including thyroid problems, rheumatoid arthritis, and other inflammatory or muscle conditions. When those are excluded and the picture fits, a diagnosis of fibromyalgia can be made.

Treatment & management

How is fibromyalgia treated?

There is no cure, but symptoms can often be reduced with a combination of approaches tailored to you. Regular, gentle activity — such as walking, swimming, or stretching, built up gradually — is one of the most helpful steps, even though starting can feel difficult.

"Pacing" everyday tasks to avoid overdoing things on good days, working on sleep habits, and psychological support such as cognitive behavioral therapy can all help. Some people benefit from medicines that act on pain signaling — for example certain antidepressants or nerve-pain medicines — prescribed and reviewed by a doctor. Standard analgesics and opioids are generally ineffective for fibromyalgia pain and are not recommended; treatment focuses on central pain modulators (such as SNRIs or gabapentinoids) when medication is indicated.

What can I do to help myself?

Staying as active as you comfortably can, keeping a regular sleep routine, and managing stress are central. Many people find it useful to learn about the condition, pace their activities, and set realistic goals. Support groups and talking therapies can help with the emotional side of living with long-term pain.

Prevention & outlook

What is the outlook?

Fibromyalgia is a long-term condition, and symptoms may come and go, but it does not damage the joints, muscles, or internal organs and is not life-threatening. With the right combination of self-care, support, and treatment, many people find their symptoms become more manageable over time and are able to stay active and working.

There is no known way to prevent fibromyalgia, but good sleep, regular activity, and managing stress can help reduce how often and how strongly symptoms flare.

Additional Common Questions

Is fibromyalgia the same as arthritis?

No. Arthritis involves inflammation or damage in the joints, whereas fibromyalgia does not damage the joints or tissues. They can, however, feel similar and sometimes occur together, which is one reason a careful assessment is important.

Does fibromyalgia get worse over time?

Fibromyalgia is not a progressive disease that damages the body, but symptoms can fluctuate with flare-ups and quieter periods. Many people find that with treatment and self-management their symptoms become easier to control over time.

Is "fibro fog" permanent?

The memory and concentration problems of fibro fog tend to come and go, often worse during flares or when sleep is poor. Improving sleep, staying active, and managing stress and pain can help thinking feel clearer.

When should I see a doctor?

See a doctor if you have widespread pain, fatigue, or sleep and concentration problems that persist, so other conditions can be checked for and you can get support. Seek prompt medical advice for new or different symptoms such as significant swelling or redness of joints, weakness, numbness, unexplained weight loss, or fever, as these are not typical of fibromyalgia and need separate assessment.
