NSFW: Is this a yeast infection, or what?

I have had this ongoing issue for maybe 2 weeks now. I also just got an STD test and have not had unprotected sex since, so it shouldn’t be anything like that going on. Basically I have never had a yeast infection and from what I read, I don’t have most of the symptoms of one, thus why I’m asking this question. So for the past couple weeks my clitoris has been itching….not constantly though and it’s one of those itches where when you “scratch” (but more like rub) it, it is so deeply satisfying. I have no weird discharge or anything, if anything I have been “drier” down there. And the itch is right on my clit. But other than that, nothing weird is really going on. There is no swelling, or burning. Maybe the tiniest bit of burning WHERE I’ve been itching, but I feel that’s gotta be related…I’m not itchy anywhere else, but the itch I do have is KILLIN ME! It’s obviously difficult to scratch in public, at work, whatever. So does anyone know what this is? Googling “itchy clit” did not yield too many helpful results aside from the suggestion of yeast infection…

I now see from looking at past Fluther questions regarding yeast infections that antibiotics can cause them. I was on antibiotics about 2 weeks ago for an infection I got in a gash in my foot…..is that the culprit? God dammit.
