Dad was moved from rehab back to the hospital. He was having some unpleasant symptoms, possibly from the Sutent, that looked the way the kidney failure looked. After two days the rehab sent him to the ER. Mom was there with him until 1:30 a.m. He doesn't appear to have kidney failure, but he did have a fever and some of his other levels were of concern so he's staying over night. His ct-scan showed no change from the last scan which is good since he's only been on the second round of Sutent for a few days.
Of course, in the meantime, his old job is in the process of changing insurance companies, so he's not showing up on either insurance and I'm trying to sort out the new insurance for my parents. This process is not fun considering that dad has many doctors and needs so much care. I'm worried that a wrong move will mean much larger bills.
Update: Dad has an infection. He's staying at the hospital on antibiotics while they watch him. He's going to keep taking the Sutent. He's not feeling too bad, and he's eager to return to rehab which I think is a good sign.
