Hello, I am looking for some advice on things I can suggest to my Dad to help with the pain and discomfort of the radiation burns inside his mouth. It has been 5 weeks since he completed treatment. He is healing but very slowly, he was told his burns were some of the worst they had seen in quite some time. His saliva glands were damaged so he is also experiencing issues with that. He is not able to eat anything more than Boost, a meal replacement shake, everything irritates the inside of his mouth and throat. He's a diabetic so many of the smoothies and ideas I've seen on other websites aren't useful to him. He is also quite stubborn and lives 5 hours from me so I can't be there to help him as much as I'd like. If any of you have suggestions of things that helped you they would be much appreciated. I know he has pain medication, but I don't know what it is exactly. I read on another post something about hyperbaric oxygen? I may have that wrong but it was apparently to aid in speeding up healing? Any advice you can give will be helpful, thanks in advance!
