@jen75, I have written extensively about my experiences undergoing radiation for cancer of the Pyriform Sinus. That type of cancer is located around the vocal cords. My voice and ability to eat/drink left me for about one year. I did two swallow studies six months apart. The second study was done after I did throat and tongue exercises daily, as directed by a speech therapist. Although I now have a tracheostomy due to vocal cord paralysis, my voice is back, and thank God, I can eat and drink. The exercises seemed useless but were very beneficial. Also, check into "red-light" therapy. A small wand runs about $20.00. Best of wishes to you.
