Fibromyalgia is a condition that causes people to experience increased pain sensitivity in multiple areas of their bodies. The pain stimulus is often not painful or unpleasant for other people. This leads to a disproportionate reaction in their body causing chronic widespread pain that also reduces their ability to function and sleep. 

Fibromyalgia does not have one defined cause and symptoms are individual. Most commonly people experience reduced range of motion, tenderness and stiffness with movement, fatigue due to pain and reduced strength, poor sleep, anxiety and depression. These symptoms all intertwine themselves and can also cause poor memory and attention, restlessness and the inability to participate in a lot of activities in daily life.
