@jdub51 Welcome to the Head and Neck group. Radiation starting tomorrow. It won't be any trouble for the first few weeks. Things get worse as time goes on, difficult but not impossible. Keep your fluids up. Eat what you can and don't worry about weight gain because you likely will find eating enough later on to be very hard to do. Don't hesitate to ask for a feeding tube if you think you can't maintain a healthy caloric intake. And please have someone to help you out after the three week point. I don't mean to scare you, just prepare you. This will be your day every day toward the end of the radiation treatments. And when you start to feel better, then you get the Chemo.
We are here to help you based upon our similar experiences. If you have any questions or concerns that the doctors don't understand, chances are someone here does. You can start your own "Discussion" as well and likely get more responses right away. In the meantime, courage.
