Septal perforation from a septoplasty, nose keeps whistling constantly, any ways to fix this other than surgery?

I have a tiny septal perforation from a septoplasty and my nose does not stop whistling, any way to solve this issue until i get surgery to fix it? I plan on saving up for a rhinoplasty and to have this fixed with the rhinoplasty but realistically i will not be able to have rhinoplasty for another year because i need to save up... so i need to find a way to stop the whistling as it is driving me crazy. And the sad thing is the septoplasty did not even work and just made it worse.
