• A common nonarticular rheumatic condition that is characterized by muscle pain, tenderness, and stiffness.
• A common nonarticular rheumatic syndrome characterized by myalgia and multiple points of focal muscle tenderness to palpation (trigger points). Muscle pain is typically aggravated by inactivity or exposure to cold. This condition is often associated with general symptoms, such as sleep disturbances, fatigue, stiffness, headaches, and occasionally depression. There is significant overlap between fibromyalgia and the chronic fatigue syndrome (fatigue syndrome, chronic). Fibromyalgia may arise as a primary or secondary disease process. It is most frequent in females aged 20 to 50 years. (from Adams et al., Principles of Neurology, 6th ed, p1494-95)
• An acute, subacute, or chronic painful state of muscles, subcutaneous tissues, ligaments, tendons, or fasciae caused by a number of agents such as trauma, strain, occupation, exposure, posture, infection, or arthritis.
• Fibromyalgia makes you feel tired and causes muscle pain and "tender points." tender points are places on the neck, shoulders, back, hips, arms or legs that hurt when touched. People with fibromyalgia may have other symptoms, such as trouble sleeping, morning stiffness, headaches, and problems with thinking and memory, sometimes called "fibro fog."no one knows what causes fibromyalgia. Anyone can get it, but it is most common in middle-aged women. People with rheumatoid arthritis and other autoimmune diseases are particularly likely to develop fibromyalgia. There is no cure for fibromyalgia, but medicines can help you manage your symptoms. Getting enough sleep and exercising may also help. nih: national institute of arthritis and musculoskeletal and skin diseases
