Diane, It is awful when nobody has the symptoms you have. I know of Breast cancer survivors who go thru it due to tamoxin, I know my mom had it real bad due to menopause. It can really beat you down. Hopefully someone can put your mind at ease and give you awnswers. Everytime I go to my ent with a complaint he says it was due to radiation. Not that he is wrong, it just leaves me with an empty feeling.
