I am a married man but in January of 2007 I had a one-time unprotected sexual experience (vaginal intercourse) with an older married woman. Around July of 2007 I went through an on-line provider of STD testing who sent me to LabCorp. My full panel including HIV-1 EIA according to the report was negative at that time, which I estimate was over five months post exposure (probably closer to six). I have had zero outside expsoure since this event. My wife is HIV neg as well.
About a month ago I noticed my tongue had a pronounced white coating on it. I vaguely remember smoking a cigar the night before or maybe that day before, but this coating caught my eye. I smoke very very rarely and drink rarely. It is a thin white coating that at close inspection looks like very many dots, almost like white taste buds. There is no pain, no bleeding, no irritation, just this whitish "haze" I also have a whitish coating on both sides of my tongue under the dorsal top that appears equal in size on both sides when I extend my tongue. It is slightly more pronounced in the back, like faint white stripes, but more like the same white dot texture at closer inspection that is on the dorsal surface of my tongue.
When I brush my tongue, my tongue is more pink but still has some remnant of the white appearance on the dorsal surface and the areas on the side immediately below the dorsal surface when my tongue is extended.
My question is, I tested negative five months post exposure last year and have had zero exposures since, but I do know tests can be wrong and oral symptoms can be one of the first signs of HIV infection. Do I re-test or stop staring in the mirror and put all this junk out of my head and move on?
Thanks.
