Traumatic life events and its impact on fibromyalgia symptoms through serotonin activity on pain perception and personality traits.

Fibromyalgia is a chronic syndrome characterized by widespread muscular pain and tenderness with no evidence of soft tissue inflammation. Early-life stressors and traumatic events have been described to increase the risk of developing a number of psychiatric conditions, and conditions related to chronic pain in later life such as fibromyalgia on the other hand. In this overview of the literature on the topic, we present the impact that traumatic life events can have on fibromyalgia symptoms through serotonin activity on pain perception and personality traits.
