The best thing to do is ask questions so your prepared for everything! I believe I had my nasal packs in for 2/3 days, you can’t breathe through the nose at all within those days and for quite a while after your nose will be constantly blocked and breathing will be a struggle through the nostrils, my surgery was in March and I sometimes still have difficulty breathing through my nose however this isn’t very often.
The day of your op ( that night after surgery) I felt fine, I actually felt a lot better than I thought I would, then second day my whole face was very very swollen, black eyes, swollen forehead, I looked awful and felt awful (don’t forget I have open so a lot more work is done) but then saying that day three I felt absolutely fine again, swelling went down so so quickly and I felt/looked normal within 48hrs of day two.
Everyone is different but honestly surgery, recovery and results have been amazing.
Best of luck!x
