Dear Colleagues,

Fibromyalgia is a term utilized by rheumatologists to describe certain common musculoskeletal phenomena that cannot be easily ascribed as enthesial in derivation. In the analogy of the blind people and the elephant, we as rheumatologists call it fibromyalgia, while physiatrists refer to similar phenomena as myofascial pain syndrome. The phenomena, which the two terms identify, do not precisely mirror each other, but rather form more or less overlapping circles. Fibromyalgia has long been a controversial diagnosis, not only with significant supporters and deniers of its very existence, but also problematically used as a “waste basket” diagnosis, when the physician could not identify the source of a patient’s complaints. The latter often relates to insufficient education/exposure to musculoskeletal problems during the training of primary care physicians and to the highly focused training/experiences of those of orthopediatricians.

Initially diagnosed by rheumatologists on the basis of reproducible patterns of trigger/tender points (with the assurance that tenderness was wholly limited to those sites), the diagnosis fibromyalgia seems suggested for general or regional body pain. The latter compromises distinguishing it from allodynia, where touch sensations are perceived as pain. Part of the challenge has been non-musculoskeletal symptoms routinely associated with fibromyalgia (e.g., sleep disturbance, fatigue, headaches, abdominal pain). Additionally, the analogy of dogs having both ticks and fleas appears relevant. Fibromyalgia may occur in isolation, but its symptoms are observed in other disorders, including major rheumatologic diseases (e.g., rheumatoid arthritis, lupus), with ensuing distraction and difficulties determining what problems are related to that underlying disease and what to secondary fibromyalgia.

The Special Issue is a point–counterpoint conversation related to fibromyalgia and allodynia, providing the opportunity to publish a significant number of articles on existence, diagnosis, pathophysiology, intervention and patient education. This Special Issue encourages submissions addressing all aspects.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Rheumato is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
