Thank you Christine! He does have the magic mouthwash with lydocaine and maylox, it does not have the benedryl so maybe that would help? The Dr. also gave him Gelclair. He is on Oxy but I have never heard of the patch. I have tried all of the drinks but as of yesterday he was able to eat only oatmeal with a lot of butter which got him up to 1500 calories and water. Today barely anything, a few bites and sips. He said everything burns like fire and after he takes a few bites gets chills because of the pain. Final home stretch and I just wish I knew more to comfort him.
