I have cfs also. It is very comforting to know that I am not the only one who gets this flushing from the waist up. I thought I was going thru early menopause. I also noticed that no deodorant was working on me because of the sweating. I wish I could be of more help but like I said it is comforting to know that what I am experiencing is not in my head only. God bless and hope you feel better.
