Mucus buildup and congestion 3 years after cosmetic rhinoplasty

I had a deformed nose after a car accident. Had a functional surgery and then a cosmetic surgery a year after. After the cosmetic surgery (3 years ago) I started experiencing mucus buildup and congestion in my left nostril. That side was particularly deformed and probably required more work. ENTs say they don’t see a structural issue. I have to blow my nose 50 times a day. Rinsing with neti pot and flonase help to some extent.
