What happens if you don't like your nose job?
Well, nothing really happens unless you choose to make something
You could talk to the doctor that did the job and tell him why
you are dissatisfied, and (depending on the policies of the clinic
and the contract that you signed), he may agree to correct the
perceived problem, which may or may not cost you a lot more money,
depending on what you signed and the policies of the place where
you had it done.
