I had Septorhinoplasty 7 months ago and everything was healing well but in the last 2 months I been getting crusting that is yellow and sometimes with a weird smell. The smell comes and goes and the crusting is not a lot is just like cover sheets that forms over my skin inside my nose. I also have burning and discomfort after blowing my nose. My nose feel really stiff inside all the time. My surgeon checked me 2 weeks ago and he said everything is healing ok. Why do I keep getting this crust?
