What Can Remove Hardened Tissue Inside My Nose. Feelings Like

What can remove hardened tissue inside my nose. Feelings like cartilage between inside of the nostril and the outside of the nose. It's been there for many many years it does not appear to have grown larger just annoying a little bit because it causes the left side of my nose to look protruded slightly it feels like a very thin layer of cartilage tissue perhaps it came from irritation over the years. any suggestions
