My sister and I went to see Dad at the hospital after church. Our pastor visited him yesterday. He was feeling much better and was eating lunch when we were there. Turns out that he had some virus and a UTI, so the doctors prescribed some medication and sent him home! He seems to be fine now, but he'll have to eat bland food for a while and go back to the doctor for a follow-up. I'm just glad it wasn't anything worse!
Thanks for all of your good thoughts, prayers, etc!
