So back in September i had an Hiv scare. Receptive Oral sex (i know its no risk) anyways about a month later i got a white tongue and lump in throat feeling. Tongue is still the same 5 months later. Ive had 2 4th gen HIV tests (10 weeks, 6 months) all negative. I have a pic on my profile of my tongue. I know many people have had this same issue, and no explanation. Any and all help is appreciated.
