I had a nosejob when I was 22 - it cost me nothing as it was done on the NHS (no medical reason, I just had a humungous hooter, and for some reason my GP was happy to refer me for surgery. Had to wait three years, though).
Beforehand, the surgeon took me through what they were planning and explained how it would look.
It sounds daft, but it really didn't hurt too much - the idea was much worse than the reality. The day after, I did feel as if I had been punched, and my face was swollen, with two fabulous black eyes and a lovely plaster "beak", but it wasn't painful really. The wadding inside my nostrils was removed before I went home and I felt fine within a couple of days.
The beak stayed on for about 10 days. Yes, you look scary, although I do remember wandering bravely round Waitrose with my mum at one point. It did take a couple more weeks after that for the bruising to completely disappear, and the last bit of the swelling to go down, but once the beak was off (and with the application of lots of concealer) you wouldn't have noticed anything odd.
I was dead chuffed with the results - as soon as the beak came off I knew it was a vast improvement. They narrowed my nose and took out the bulbous tip, with no visible scarring - amazing, really.
The top of my nose has been a little numb ever since, but who cares?
Go for it, it is one of the most successful forms of plastic surgery, and you will be so glad you did.
