Fibromyalgia is a condition related to musculoskeletal pain followed by signs such as fatigue, sleep, poor memory, and mood swings. Fibromyalgia intensifies the pain by affecting the way your brain and spinal cord differentiates between painful and nonpainful signals.

The onset is commonly observed after a trigger, such as surgery, infection, psychological stress, or physical trauma. Many people with fibromyalgia may have tension in their muscles, headaches, temporomandibular joint 9TMJ) borders, anxiety, depression, and irritable bowel syndrome.

Women are more likely to be affected by fibromyalgia than men do. Individuals with fibromyalgia may have some other neurological disorders resulting in tenderness in the affected area.
