Help! My nose has changed shape?

You will need to see a rhinoplasty surgeon for an assessment of your problem. It is unlikely that your nose will change back to the previous shape.

I would recommend consulting with a rhinoplasty surgeon.Find a plastic surgeon with ELITE credentials who performs hundreds
of rhinoplasties and rhinoplasty revisions each year. Then look at the
plastic surgeon's website before and after photo galleries to get a
sense of who can deliver the results. Kenneth Hughes, MD Los Angeles, CA

You need to see a plastic surgeon to be properly evaluated for your nose. A GP does not do tsurgery and can't offer you much help.

It's important to have clear expectations with your ENT/ facial plastic surgeon when discussing your nose. To prevent the tip from drooping upon smiling and animation, releasing the depressor septi ligament is necessary. The bump on the bridge can be shaved down, however osteotomies may be required if it's a large and noticeable bump. It is best to go see a surgeon who specializes in rhinoplasty for best results

Following the advice from a surgeon on
this or any other website who proposes to tell you what to do without examining
you, physically feeling the tissue, assessing your desired outcome, taking a
full medical history, and discussing the pros and cons of the operative
procedure would not be in your best interest. I would suggest you find a
plastic surgeon with extensive nasal surgery experience who is certified by the
American Board of Plastic Surgery and ideally a member of the American Society
for Aesthetic Plastic Surgery (ASAPS) or a facial plastic surgeon that you
trust and are comfortable with. You should discuss your concerns with that
surgeon in person.Robert Singer, MD FACSLa Jolla, California
