Around 3 months ago, I had an HIV scare. I had an encounter where I fingered a woman of unknown HIV status. Around 11 days after exposure, I had a panic attack, because I thought I had oral thrush. However, I have tested negative for HIV at 4 months post exposure. Regardless, I have been experiencing the following symptoms:
After my panic attack, I thought I had oral thrush, and applied oral gel for a couple of weeks, but it did not make a difference. After this, I realised that I had developed dry mouth, not oral thrush. I have also been experiencing post nasal drip. I am not sure if it is caused by the dry mouth, or if the dry mouth is causing it. Regardless, if I don't swallow frequently, mucus builds up at the back of my throat. I cannot seem to spit it out, and I have to swallow it.
Also, if I talk for too long, or go without drinking water for too long, my tongue dries up. Furthermore, by the end of the day, I have white gunk built up at the back of my tongue, which I have to clean out with the back of a toothbrush. I am fairly sure the stuff that comes off is mucus/mucousy spit, because it is clear and gooey. In addition, my spit does not seem to be as thin and clear as it should be, as it seems more thick and white.
What could be the cause of all this? The most annoying thing is that I have to keep drinking water, otherwise my tongue does not remain moist enough. It is not caused by a cold, because I have been experiencing these symptoms for a while. Could it be caused by some respiratory issue? If I look up my nose in the mirror, one nasal airway seems to be almost closed.
I am not on any medications at the moment, nor do I mouth breathe.
