And antibiotic resistance doesn't mean the thing you have now is going to suddenly change and kill you. Antibiotic resistance is about changes in how bacteria in general respond to antibiotics in the overall population over a very long period of time.
Doctors are very aware of antibiotic resistance as a science, and prescribe to minimize that effect. But you don't have to worry about the bacteria in your sinuses doing anything more sinister.
