i am surprised to hear you say that you have connected with a survivor program, and haven't run over there immediately. To hear you say that you have great MD's, but "..they aren't fully on board.." concerns me. In my opinion, to really get the assistance and results you desire demands that they all talk with you, and about you, and know your history and goals.
I have had most of the same post radiation issues that you are dealing with, and they were all anticipated and explained by my MD team.
All of my MD's here a Dana Farber meet and talk about me. I often see them, and talk with them, in the cafeteria and hallways. They discuss my case and issues together, and I can see them and hear them doing it. I can see them working together as a team, and i can feel the results. Joining the survivors program here at DFCI has lifted an enormous burden off of me and my wife. I guess I just expect every survivors program to work the same way.
