The same thing happened to me. My surgery was scheduled for the Friday and I woke up Monday with sore throat and very congested sinuses. Since I had a bad experience with the whole pre certification period with my insurance and the coordinator from the doctor's office, I vowed nothing was going to stop me, not even a little cold. I made an appointment with my family doctor and he loaded me up with antibiotics and gave me 2 shots. Needless to say, I was good to go come the morning of my surgery. (July 25, 2008).
