Re: Could this be CFS?
It *could* be CFS, but CFS shares symptoms with many, many other illnesses. Could be gluten alergy (or some other alergy), an auto immune disorder (there are hundreds), anemia, vitamin deficiency, hormone imbalance, or dozens of other possibilities. It's usually a frustrating process trying to get a diagnosis, but if it's affecting your life enough, you just need to start going to doctors and ruling out the possibilities out one-by-one, blood test-by-blood test, until you can get a diagnosis.
I really, really hope it's not CFS. Good luck!
