Hi @ggg80206 I didn't get a chance to welcome you to our group. I see you have been well served by many who have been down a similar path. Left tonsil and sinus in my case twenty-four years ago and I'm still kicking like others here.
The radiation will get a bit difficult to handle near the finish line and likely continue to cook for several days afterwards with a very slow recovery, similar to a burn as far as recovery goes. This is a great place to ask your questions and get a little encouragement during and after your treatments. As Sir Winston often said, "Courage."
Welcome and good healing.
