Hi all....
Guess What?? I found out that it was my thyroid ! It had completely shut down. Due to treatment.
My guess is radiation, since my throat was mainly the target. I was tested and just started pills 2 days ago. Will post again and let you know how things are going.
So I am very hopeful my torture of the hot flashes & chills will be over...!!

I am sure I will be able to recover much faster with much needed rest.
Thanks for all your input and help.
Diane
