Hi Athelia!
I'm new to the board, don't even know if i can help you with your question, I can only tell you what I have experianced.
I have both CFIDS/FMS and I have had fm for a year this month, and the other for 7 yrs. I was hard for me to distinguish the 2 at first. with CFIDS my tachycardia starts in and i have awful headaches a sore throat and a low grade fever and I feel as though i have the flu, with the muscle aches also and it's hard for me to function.....no energy at all!
With Fibromyalgia, I have pain in my shoulders, neck, arm, back, hips, legs, elbow. hands....and the list goes on. with fibro, you never know on any given day where it will be when you wake up the next morning, depending on if you got any sleep the night before. I have been in a cfids flare for 2 weeks now andI haven't had a good nights sleep In while, even on all the meds I still have trouble sleeping, or I will sleep and the next morning I feel as though I hadn't slept at all. I also have irritable bowel syndrome, vetigo.....oh annd lets not forget!! fibro fog!.....I hope I was able to help you some...as it's hard to think right about now.
Hope You Get To Feeling Better!

Hugs Coming Your Way!
