Update
Dad's doctor called this afternoon to say he was disappointed in dad's condition. He feels he is getting worse instead of better. He has ordered a full battery of tests, and we should have the results tomorrow. I went up to see dad this evening. He recognized me and asked for water. He kept his eyes closed except for about one minute, during which he had just one eye open. I washed his face and helped him drink a large cup of ice water with a straw, then he fell asleep. His nurse said he ate a full meal for dinner, but never opened his eyes then, either. She said he was mostly non-responsive all day long. I'll let you know what the tests show tomorrow.
