Six weeks ago, I performed unprotected oral on another man, without ejaculation, but I know there was precum present. I had gums that would occasionally bleed at the time, but I don't recall bleeding during the contact. I asked him about his status - he said he was HIV negative and that he doesn't "do this kind of stuff" often enough to be concerned, but didn't mention having gotten a test. I also performed unprotected cunnilingus on Jan. 1. Last week, I caught the flu or a nasty cold, fever and sweats for a day, lymph nodes in neck, groin, and under one arm were swollen, and are still slightly swollen now. A rapid HIV antibody test came out negative yesterday, about six and a half weeks after exposure, providing me some peace of mind. I do have a symptom, however that continues to worry me:
Over the past week I've developed a white patch on the middle of my tongue, that's gotten somewhat bigger and more visibly noticable, with a smaller spot behind it. The larger patch is about 1/8 inch diameter and irregularly shaped. I have what I assume is a "geographic tongue", and often a white fuzzy looking coating, that brushes off fairly easily. The new patches of concern do not brush off and feel a little hard, and raised slightly from the rest of the tongue. They appear similar to the gunk that builds up on my tongue that I can brush off, but these ones remain and are slightly tender to touch. They look like larger white tastebuds, but appear similar to pictures of mild thrush cases.
My questions:
1). I know you can't diagnose thrush without seeing the patient, but are my symptoms consistent with a thrush infection?
2). If this were an HIV-related thrush infection, would I have tested positive yesterday, or is it possible to have such a case BEFORE antibodies were detectable, as part of acute infection?
3). How conclusive do you think yesterday's test was in terms of being an accurate negative result?
