Fybromyalgia syndrome is a common and chronic disorder characterized by widespread pain, diffuse tenderness, and a number of other symptoms. The word “fibromyalgia” comes from the Latin term for fibrous tissue (fibro) and the Greek terms for muscle (myo) and pain (algia).
Although fibromyalgia is often considered an arthritis-related condition, it is not truly a form of arthritis (a disease of the joints) because it does not cause inflammation or damage to the joints, muscles, or other tissues. Like arthritis, however, fibromyalgia can cause significant pain and fatigue, and it can interfere with a person’s ability to carry on daily activities. Also like arthritis, fibromyalgia is considered a rheumatic condition, a medical condition that impairs the joints and/or soft tissues and causes chronic pain.
In addition to pain and fatigue, people who have fibromyalgia may experience a variety of other symptoms including:
- Cognitive and memory problems (sometimes referred to as “fibro fog”)
- Sleep disturbances
- Morning stiffness
- Irritable bowel syndrome
- Painful menstrual periods
- Numbness or tingling of the extremities
- Restless legs syndrome
- Temperature sensitivity
- Sensitivity to loud noises or bright lights
Fibromyalgia is a syndrome rather than a disease. A syndrome is a collection of signs, symptoms, and medical problems that tend to occur together but are not related to a specific, identifiable cause. A disease, on the other hand, has a specific cause or causes and recognizable signs and symptoms.
