Can I Have a Small Hole in Septum and Will It Heal on Its Own?

I have recently had really bad nasal congestion. I was put on Nasonex. This seemed to help a little however everytime I breathe in my nose makes a whistling noise. There does appear to be a scab inside on the septum and if I am rubbing ny nose it will dislogde and start to bleed. The Dr. said I did not have a hole in the septum. But I am wondering now if it might be a small enough hole she didnt notice?
