Scar in both nostrils of nose that won't go away. it's painful if i touch or move my nose. i was taking zentonna but prn. could this be the reason?

Possibly: It depends on what you mean by scar. Any spray with a topical nasal steroid in it, like zetonna, can cause the nose to dry out and produce pain inside the nose in the front. However, if you are only using it as needed, that is less like. There can be may other reasons you have "scar" or pain in your nose. You should see an ear, nose and throat doctor. One thing you can try is saline mist 2x a day.
