Fibromyalgia (FM) is currently classified as a chronic pain syndrome. Its main features are chronic widespread pain in the presence of tender points (TPs) upon physical examination, sleep disturbances and fatigue, although patients also report a variety of other complaints. ⋯ Complementary and alternative medicine (CAM) techniques have not yet been fully acknowledged by scientific medicine because little is known about their mechanisms of action and usefulness. The aim of this wide-ranging review of the literature is to analyse the types of CAM techniques used to treat FM and their effectiveness, highlighting the disagreements among the authors of more specialised reviews.
