I have about a pencil eraser-size white patch in my nostril. It is flat, nontender. I went to an urgent care clinic to have this checked and the doctor was at a loss. Her recommendation was Vaseline to the area for 2-3 weeks and if not resolved, then to see my primary. Well, it hasn't gone away and it's starting to scare me. I will be making an appt. with my primary in the next week, but was just wondering if anyone else has ever had something similar. I have no sinus symptoms except for "chronic" frontal sinus pressure. No postnasal drip, no cough, no sore throat, no white patches in my mouth. My worst fear is some type of cancer. Has anybody experienced something of a similar nature?
