Thanks for all the support. I have spent part of the day looking and reading other folks posts, looking for clues. I have another apt. with my GP on thursday. Looking thru the tons of blood work I have had done, I noticed a few things that may be markers that I indeed have CFS. One site said an ESR, or Sedimentation Rate that was very low indicated possible CFS, my dr has ran that one two times in the last month, first test the result was 1 on a scale of 0-15, second test result was 2 on scale of 0-15. I also read anything odd on a brain MRI was a red flagg. I had a CT of my brain one month ago, and there were two strange comments on the report "There is dilatation ventricular system" and "Cavum Septum Pellucidum and Vergae". My blood test EBV AB VCA,IGG was greater than 8, plus I have low cortisol. If you had to choose five or ten blood tests to be done that specifically related to CFS, that you would ask your GP to run, which ones would you choose? Thanks so much for your help.
