One year in review 2020: fibromyalgia.

Fibromyalgia (FM) is a frequently encountered syndrome that is characterised by chronic widespread pain, fatigue, sleep disturbances, and many other symptoms that impair the quality of life. Its aetiopathogenesis is still unclear but, although there is no specific therapy, a number of pharmacological and non-pharmacological therapies are available. The aim of this review is to describe the most recent findings concerning the diagnosis, aetiopathogenesis and treatment of FM published between January 2019 and January 2020. They include the new concept of nociplastic pain, some neuroendocrine and metabolic alterations found in FM patients, and investigations concerning not only novel applications of old drugs, but also, and in particular, complementary therapies, such as the hyperbaric oxygen chamber, ozone therapy and mindfulness-based interventions.
