Dad has been extremely fatigued for the last 24 hours. Not sure why. His oxygen levels are good, but he is just worn out. The PT tried to get him up to go to the bathroom to wash his face and comb his hair, but once he got in there, he couldn't do anymore and had to lay back down. The doctors said to expect good days and bad days. I think the extra work his body is doing in effort to heal is just wearing him out.
Mom took her computer to the hospital yesterday and read him every word I've written here as well as every heartfelt word you've written in the comments. They evoked both tears and smiles from his face. He is so grateful for each of you. Again, my thanks.
