I had open rhinoplasty a month ago. I'm happy with results. However, I'm starting to notice that for the past 2 weeks my nares alternate when I breathe. For instance today I'm breathing through my right nostril only, when yesterday I was breathing through my left. And this will last for an entire day.I'm following docs instructions rinsing with saline water and hydrogen peroxide cleaning. Clearly I'm still swollen internally but what's causing this back and forth between nostrils when I breathe?
