He has pancreatitis which they think is due to a gallstone. CT scan revealed what looks like metastic tumors in his liver. He had bladder cancer a while back and his doctor thinks it may be back. We asked if all his neurological/mental problems could mean there are lesions in the brain, and they said it's very possible. Right now they are working to stabilize him -- postassium was good but calcium was too high. Putting a ureter stent in because it's blocked (doctor said maybe from cancer). Will get a brain MRI tomorrow most likely and other tests to figure out what's going on once they stabilize him. I've made peace with the eventuality of his end. I'm most worried about my mom. She's holding up fairly well, but doesn't want to tell him about the "C" word because he's talked of suicide before if it came to him being declared terminal. So for now, we all have on our poker faces and are focused on just getting him back on his feet. One day at a time.
