WhatamIdoing Da Costas syndrome has been described as being related to CFS since the Da Costas syndrome article page was started on  here   months before I started adding to it   Also the following quote    The orthostatic intolerance observed by Da Costa has since also been found in patients diagnosed with chronic fatigue syndrome and mitral valve prolapse syndrome is from the current page here  where it has been moved from the Related to section at the end of the page up into the Diagnosis section where the CDC hypotension that I have just been discussing is referred to as being involved in the diagnosis of Da Costas syndrome and CFS I did not put that comment there and I did not put the reference number  which supports it there You probably did or at the very least you didnt remove it as being wrong so I dont have to convince you of something that you already know and accept  If you want any more links to CFS and the synonyms of Da Costas history you can find nine references that I have provided on the subpage here   Also Avnjay has not given me any indication of changing his mind and in fact has done an excellent job of rewording the introduction and the history of the topic from  to  without me having to change anything  posturewriter
