Ste44, you don't mention the level of pred you are at. I was at 8 mg (methylprednisolone = 10 prednisone) and had to have surgery. Rheumy had me double the day before, nothing the day of and double the day after. I also had discusion with anesthesiologist about how much I was on. She was ready to boost me if I needed it. I didn't. No problem. So talk to all your drs.
