Frank how long after your cyberknife treatments did you start to have swallowing problems. It will be 7 weeks tomorrow from my husbands last treatment. His throat pain is starting to subside but the swallowing is really becoming an issue. He sees his DR tomorrow for a swallow test. Dr also recomendid therapy. They did mention this complication before cyber treatments and its just hard to imagine someone like my husband who enjoys food so much never being able to eat again. Also what nutrition are you using in your PEG.
