4 days pre-op activity?

Hi all! My surgery is scheduled for Friday. I just started a running program within the last week and I noticed that my left sinus has been in some pain and I'm having drainage. I'm worried about pushing it this week... What did your doctor advise you guys the week of surgery? As far as activity levels and water intake, food intake etc? This will be my first time having surgery besides getting my wisdom teeth removed so I just want to make sure that I'm as healthy as possible going into it.
