Bumps inside nostrils after rhinoplasty. Is this something to be concerned about? (photo)

I got my stitches and cast off a week ago and noticed these bumps inside my nose that day. They are still there but they aren't red or smelling bad etc just feeling annoying. I tried to look online and came across "nasal mucosa" and "nostril polyps". What do you guys think it is? Could this be because of the pressure of the cast or because of the incisions made inside the nose? Should I be worried or will this heal on its own as the time goes by? Other than that my recovery is going well.
