question: On the left side of my throat, right next to my tonsil, there is a whitish yellow lesion. At first I suspected a cold sore but it is not a cold sore because it does not have a pit of a sore .The lesion has been around for almost a month now. I do not display ANY symptoms other then very mild pain coming from the lesion.  The doctor gave me antibiotics however they did nothing to cure the lesion. If this lesion was due to cancer, hiv , or some serious disease what would be some symptoms. Also this lesion arose when I reached the lowest most depressed time in my life. Please give me advice .
