Update...doctor says husband is responding extremely well to radiation treatments. His attitude is not great..but he received some pain medication for his mouth today and hopefully that will help him. The doctor told him to drink lots of water that he maybe slightly dehydrated and to put it in his feed tube. He seems to dislike almost everything he tries to eat...Any suggestions...I would like to see his attitude change..it is usually positive..again he refuses to have family members see him....
