For whatever reason, they took him off of his pain pump and continuous drip at the same time! We couldn't understand why he would go from all of that medicine to just a pill every 6 hours, so he's now on a continuous drop and pain pump using a different medication that won't affect his blood pressure.
There have also been some concerns about his kidney (remember, he only has one!) that they are keeping a very close eye on. They're running some tests now.
My mom is staying again tonight and I will be staying tomorrow night. My sister will be there during the daytime. Between the 3 of us, we are trying to make sure someone is with him 24/7.
We would truly appreciate your prayers as Dad recovers. His other medical concerns make this recovery much more complicated. Thank you for your support and prayers!
