I had my nose cauterized with silver nitrate on Wednesday a few minutes ago the area that was cauterized it seems a scab has come off. I looked at the scab it is white where it was cauterized and I see black lines that appear to be where the blood vessels were. I looked into my nose with a flashlight the area seems to look normal so I put Vaseline in my nose to keep it moist did is it possible that my nose has healed or could my scab fallen off prematurely?
