Dude, sorry about the cold. At one point I thought my surgeon would not cancel surgery unless you had a fever, but a friend who was scheduled with same surgeon as I had. Had her surgery canceled becuz of the congestion of the cold. So only your surgeon knows for sure.
I think the best thing to do would be to call your surgeon's office and tell them what's going on. Maybe they can give you some advice or maybe even a scrip.
Good luck, I am rooting for you. Keep us posted.
