Eisinger 3 in an editorial comment raises the issue of heterogeneity permeating Martinez-Lavin s proposition. Since it is difficult to establish a traumatic trigger event in all cases Eisinger considers multicausality as more reasonable than a single post-traumatic etiology for all cases. Felix and Fontenele 4 further explored this venue speculating that the orthostatic intolerance symptoms seen in the majority of fibromyalgia patients are a consequence of sympathetic hyperactivity. The idea that a COMT val-158-met polymorphism may cause higher cathecolamine levels has been explored 5 . Loevinger and colleagues 6 have shown that the metabolic syndrome is more common in individuals with fibromyalgia who also have higher body mass index blood .
