Kim - Thanks for your input. My daughter and I have been talking at great length to my husband and doing all kinds of research on the Internet. We have finally figured out that when he says chills, he is talking about an inner shaking that has nothing to do with the temperature. His body temp is always normal. His hands, feet, etc are warm. We think this has to do with the severe depression he has been in since his tumor came back. We are going to see a psychologist and try to get him some relief. The shaking is an intense inner tension I think.
