A 2010 study published in the Journal of Clinical Sleep Medicine showed that adults with fibromyalgia (FM) are much more likely to have restless legs syndrome (RLS) than healthy people [1]. According to Nathaniel F. Watson, MD, one of the study authors, “Sleep disruption is common in fibromyalgia and often difficult to treat. It is apparent from our study that a substantial portion of sleep disruption in fibromyalgia is due to restless legs syndrome.” [2]
