Fibromyalgia is a chronic condition of widespread pain and profound fatigue, recognised by the NHS.

The pain tends to be felt as diffuse aching or burning, often described as head to toe. It may be worse at some times than at others. It may also change location, usually becoming more severe in parts of the body that are used most.

The fatigue ranges from feeling tired, to the exhaustion of a flu-like illness. It may come and go and people can suddenly feel drained of all energy - as if someone just pulled the plug.

Symptoms besides pain and fatigue often include:-

Unrefreshing sleep

Headaches

Irritable bowel

Cognitive disturbances - brain fog

Clumsiness and dizziness

Sensitivity to changes in environment - e.g. bright lights, noises, smoke, etc.

Allergies

Fibromyalgia is a common illness, with an estimated prevalence of between 2.9 and 4.7%.
