How does Chronic Fatigue differ from ... ?
This is what the Center for Disease Control says about the latter 2:

Chronic Fatigue can also be an aspect of 'gulf war syndrome' symptoms, so obviously, multiple symptoms are present. Most any of the anemias could cause fatigue, wouldn't you think? An often undiagnosed 'chronic fatigue' is fragility of the red blood cells (low functioning) & it doesn't show up for awhile in the blood counts, but a 'retic' ratio might give an indication.
What is your situation? What employment do you have? Do you recall when your symptoms started & whether anything was happening differently than before that?
