Fibromyalgia (FM) has always been a controversial syndrome. In early discussions, researchers were divided into two camps, usually defined as believers who tought this syndrome was a particular disease entity resulting in a condition of significant disqability; non-believers considered this syndrome to be a chimera of an (for one or an other reason) interested coalition of patients and medical doctors. During the past years, the confrontation between these groups have regularly been quite heated. However, an new element seems to have entered the discussion. The tenacity of some resaerchers who developed the concept seems to have weakened. Meanwhile, hypotheses quickly changes. This paper aims to describe the recnt evolution by means of a review of the most recent literature (1995-1998).
