NUGENT and Danny,
I am 16 months post treatment. The quality of my voice has changed a fair amount, although I've always been able to talk. I had never been accused of being quiet before, but now I have to repeat myself, and it's not just my husband's selective hearing. I also cannot sing most of the time.
Has she told her ENT about this? I wonder whether s/he might be of some help. Did the speech therapist offer any exercises?
She also may want to see someone (ENT or GI?) about the choking and eating problems. I ended up with my throat being closed and was completely dependent on my feeding tube for 10 months after radiation ended. Since October I've had 8 throat dilations, the last one today, and my throat is now open enough that I can eat most foods (but no bread and little meat) and even swallow my meds; I was able to finally pull out the feeding tube a few weeks ago.
Best of luck to you and to her.
Susan
