I’m a bit nervous

I’m Planning on getting a septoplasty done at some point, and I have a few questions that Google isn’t too good at answering

To start, what should I expect after it’s done? Like will there be pain and how long does it usually take to heal?

And does it change the shape of your nose form a side profile view? My nose has a small bump and I was hoping the surgery will make my nose straight or at least curve in like a button nose in some way (Which is probably too unrealistic)
