Are you sure that fibromyalgia is the same as chronic fatigue syndrome? Chronic fatigue syndrome was just being tired all the time. There were no other symptoms. Now maybe since then they’ve wrapped it up under the fibromyalgia umbrella. But it sounds like there’s a lot more there there with fibromyalgia.
My wife has been diagnosed with fibromyalgia and it seems that it is just chronic fatigue syndrome with additional symptoms. The doctor presses on certain pressure points and if the patient responds with obvious pain it is considered fibromyalgia.
