do lab tests reveal a problem with the immune system in cfids people? i have been diagnoised with fm and all tests show normal.what differentiates cfs from cfids? many of the posts here do not state which syndrome people have. some say that people with cfs can sleep but don't feel like they have rested. people with fm have to take sleep meds because they can not sleep without them. some say they have to stay in bed where i can not stay in bed because the pain won't let me.are we suffering from variations of the same thing or are these things different? if cfids can be diagnoised with lab tests would'nt it be different from fm? just a lot of questions as i stay confused about many of the posts. help me understand if possible. thanks, and best to all.
