Rhinoplasty doctor putting me not fully under to go in and scrape away scar tissue? I got a nose job 2 years ago (Photo)

After steroid shots I still don't like how my nose looks from the side. My doctor says there is still a lot of scar tissue built up and that we can do a procedure in her office where I'm not fully under anesthesia and she goes in and scrapes the scar tissue. Is this normal? Will this cause more scar tissue? She also wants me to pay for it. Is this something that would be the doctors fault as she should've known I have thicker skin or maybe she made my nose too small? Included goal nose she made.
