@Granny Hatchet, he could still have a low grade infection a festering bladder infection, even the bed sores. His blood sugar that high is dangerous but you know that. Hopefully the doctor can talk some sense into him. This may sound harsh if it does forgive me but if the doctor tells him he needs to be in the hospital and he refuses can you tell him or get away with telling him gently but firmly that if the doctor says he needs to go to the hospital, you don't want him to come home until he has been there and is feeling better. Voice your worry and concern for him and his well being? Think that would influence him? Oh, dear lady you don't need this stress, I know and you would be feeling better yourself if you knew he was getting the care he needed.
