Hi Jim, It is good to hear from you again.
I had 40 radiation treatments five years ago, so I know what you are going through right now. I was very successful in treating the burns with aloe. I started with aquaphor, tons of it just right after radiation; but later in the day, I would rest with slices of fresh cooled aloe on the radiated area. I would even cut a small piece, and let it melt in my mouth. If you are willing to experiment with this, I can give you further instructions.
Best to you, Loli
