Would it be okay or a bad idea to have a 3rd rhinoplasty?

I had 2 rhinoplasties, done 2 years ago. The 2nd one was mainly done for looks. Now after the 2nd one, I still have some issues with the looks (a small bump in the middle of my nose & the tip goes down when I smile), but also issues with a tiny amount of blood everyday, sides of my nose moving when I breathe, & nose whistling from smaller airways. Would it be worth it to try to fix these things (with the same doctor) a 3rd time, or do you think it would just cause more problems?
