is the only one I know of. The docs can poke and prod all day long and it doesn't hurt, but make me walk around the block and I'm in agony. I should also mention that I used to be pretty active - went to the gym and stuff. I don't think there is a test for CFS and I'm a little afraid that is what the doctors are going to say I have since they can't find anything else. I am currently taking classes at the local college and am having a horrible time trying to get them to understand that I can't physically get to campus. With all the controversy about CFS, I'm afraid that would make the fight even harder.
