We had amazing success with a generic prescription for Biafine. It's called Prutect. Specifically this particular cream. He got a different brand once and it was completely different. My boyfriends neck stayed really good up until the very end. He put it on 3-4 times a day. Not within a couple of hours of treatment but, immediately after treatment. It is very soothing. The nurses were amazed. He's less than 2 weeks out of treatment and his neck is back to normal. We found also, that Aloe Vera gel from the health food store was very healing when he swished and swallowed. Not very pleasant though... It's hard to watch a loved one go through all of the pain and suffering with not much you can do other than research. I wish you all the luck in the world...
