Fibromyalgia
A disorder causing widespread musculoskeletal pain and fatigue.
Definition
Fibromyalgia is a chronic condition characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and problems with memory and concentration often called "fibro fog." It is thought to amplify how the brain and spinal cord process pain signals. As an invisible illness, it is frequently misunderstood.

Many invisible illnesses begin with vague, intermittent symptoms such as fatigue, pain, or changes in weight or mood. Because these signs are non-specific and can come and go, they are frequently attributed to stress or overwork, which is one reason diagnosis is so often delayed.
