We have mentioned it but I will mention it again, especially now that he's eating more and still losing. It's worrisome, although he says he's feeling better, more energetic now than he has in some time. We are waiting on results from chest, neck and abdomen CAT scans which might tell us something. She said this was the next step when I questioned her on what we're doing to ensure there isn't something else going on. She's the one who mentioned there could be, even cancer which freaks me out. Praying it's just a reaction to the prednisone like he believes.
