Well, not really sure about the temperatures..only the mouth is .2 less than the rectum. Anyways the good news is that my husband is having a good day today and they believed his electrolytes were out of wack. He has colour back in his face and is in good spirits. He is eating some pureed foods and also seen a social worker who was very informative. His cancer is behind his tonsil and is quite advanced. Thank you all again..
