I was diagnosed with same cancer, same place. I finished treatment June 2011, and still have voice issues. Sometimes it works awesome and I sound close to normal, and then the next day I sound like a frog or else my throat is so sore I have to whisper so as not to irritate my throat and make myself cough which is not good. I have been suffering from a huge amount of phlem the last month or so and it has made everything seem worse than usual. Have any of you had any problems with your thyroid? I have started to get extremely fatiqued lately, the no motivation, I am not moving feeling.
