I've noticed that there are some singers on the board and have a question for you: Other than hoarseness, have any of you noticed a problem with shortness of breath, meaning, you're not able to hold the notes as long as you were able to hold them before contracting CFS/FM? I'm 36 and have found I can't hold the notes as long as the 70+ yr. olds in a choir I recently sang with! I should also note that I work out regularly - inspite of the CFS and the accompanying misery (which is worse if I don't exercise regularly), so I am in (relatively) good physical shape. I never worked out before the CFS and had plenty of vocal power and breath. I also noticed my abdominal muscles, which used to be very strong, shake like crazy when I do abdominal work, even though I've been doing them for over 5 years (!). They never did that before. I don't get it.
