Antibiotics before MVD Okay?

Hello again all! So, I'm scheduled for MVD on July 9, but I'm about positive I've come down with yet another ear infection/sinus infection. If I see the doctor tomorrow and get antibiotics will it still be okay to have my surgery done on Tuesday? I plan on asking the neurologist in the morning, but I'm worried about this now, so I thought I'd see if anyone knows. Thanks so much!
