Fibromyalgia and sleep

Fibromyalgia is a chronic pain condition that involves complex pathogenic mechanisms and multiple symptoms. Most patients with fibromyalgia experience poor sleep, which is bidirectionally related to pain. In this article, we discuss the symptoms of fibromyalgia, the pathophysiology underlying pain and poor sleep in patients with fibromyalgia, the relationship between pain and sleep, and the subjective and objective features of disturbed sleep in patients with fibromyalgia. We also present up-to-date evidence regarding the effectiveness and adverse effects of pharmacological and nonpharmacological treatments for fibromyalgia and provide sleep recommendations for patients with fibromyalgia.
