Michael-after they rule out that there is no infection-they say the Temperature spikes are common. Dad's temp is at bay-His treatment has been delayed for a week (due to his little episode and mouth sores.) He is being kept here so we can ease him into the peg. It's great, I'm emailing from his room. His labs are good. He will be discharged Friday for readmission Monday am. The treatment is beginning to take a large toll on his energy-that is to be expected.
