Matt,
You definitely chose a great hospital. I spent 5 days on two different occasions for thoracic surgery. UOP and the doctors are as good as you can get for serious medical care. Specialist & surgeons are some of the hardest workers I have ever met. And they genuinely care about your health and your outcome. This was my experience, I'm sure you had the thoughts.
Now, get back to work. Laying around won't help!
