I had mine done about ~2 months ago. I like the result so far, but I'm scared that the tip is going to droop lower as the swelling goes down, as that's what it used to look like before. I got the dorsal hump removed, my nose was straightened and shortened by approx. 5mm. It used to look kinda jewy.
I couldn't breathe for about 2 weeks after that and could only start using rinses and such about a month into the healing process. Had lots of bruising, especially on my eyelids. Dr says it'll take about 1.5 years for me to see the final result since the tip of my nose has really thick skin and that's where most of the swelling is (right now my nose is kind of wide with a round ping pong ball tip, but it sounds a lot worse than it looks)-
I hated the anaesthesia, I hated waking up from it and the first few days were horrible. When they took the bandages off my nose was greasy and full of whiteheads. That has since gone away but the skin is still oily and there are lots of blackheads I can't get rid of (partially because I don't want to apply unnecessary pressure to my nose, partially because they're stubborn). My mouth was really dry for the first 2 weeks. My breathing is now back to normal, if not better than it had been before the surgery. My sense of smell is a bit dulled but I expect that to change in the coming months. Some of the tissue still feels numb.
Would I do it again? If I really had to. I'd wanted to get this done since I was 14, and even at the peak of swelling I still thought it was worth it. If it turns out well, I won't get another because I don't really care about having a perfect button nose, the one I have right now is fine.
If you're the kind of person who is obsessed with physical perfection/are looking to get super smoking hot and model tummy tea on instagram, I wouldn't recommend it. If you just want to fix your breathing, a septoplasty could be a (more painful) option but that doesn't really do much in terms of appearance.
Overall, if the rest of your face is good you'll look better. If not, you won't see much of a difference.
