Three months post rhinoplasty. I could feel this small bump on bridge and Doc says it is a piece of diced cartilage that was put on bridge it was not wrapped in anything. If it is massaged it pushes down but comes right back up. It is now making a white circle on my bridge where it is. The bump is not noticeable but the small white circle over it is. The circle is not quite the size of a pencil eraser. I massage it but it's not going down. What can remove this
