One month post septoplasty and turbinate reduction and I have a lot of stuff in the inside of my nose, how can I get it out?

I had my septoplasty turbinate reduction surgery one month ago and I have cleaned out my nose as instructed. My concern is that there is large black/green looking things stuck on the walls of the inside of my nose and I can't get them out no matter how much I use neilmed nasal rinse or my saline spray. I'm concerned because I don't want it to cause any type of infection with it being there. They look like large boogers but they just don't come out and it's blocking my air way. What can I do?
