I’m impressed that you had the gumption to go back and try a second time! Most people that I’ve talked to said they get about a year of breathing clear before their nose stops back up. If it was a good chance of it never needing to be done again then I might consider the surgery, but as it is I just open my mouth a lot. My wife says I do that a lot anyways! Seriously, I figure there are a lot worse things than a clogged nose.
I wouldn't have it done, but the polyps block my passages and I can't get any air. I have one now that is so large you can see it . (If you care to look). Im going to hold off a few more years until both sides are blocked.
