Hi there! I had rhinoplasty 3 weeks ago and inside my nostrils there are masses of... something! I thought it was snot/debris but I have tried to remove it and it feels stuck to the inside of the nostril. It feels very large and lumpy but also as if it has a smooth surface. I use sinus rinse every night. Is there anything else I can do to remove it? What could it be? Thank you!
