Closed rhinoplasty/septoplasty 1 year ago, haven't been able to breathe well. Surgeon advising another surgery?

Hello. I had a closed rhinoplasty/septoplasty one year ago. I haven’t been able to breathe well through my right nostril sine the surgery was performed. I have seen the surgeon a number of times and have expressed that my quality of life has been seriously affected. The surgeon dismisses my problem and gives me a steroid injection. Now that I am at the one year mark the surgeon is advising another surgery to open the airway. I feel very anxious trusting this surgeon again. Advice on proceeding?
