I had sex one week ago with someone I don't really know, and I've been experiencing some strange symptoms since then, that lead me to believe I might have contracted an STD, most likely herpes. We only engaged in vaginal sex, and he wore a condom the entire time, but I realize that does not offer absolute protection.
About 3 days after the encounter, I started getting an odd sensation in my left labia, which I can describe as sort of a buzzing or vibrating. It almost feels like I'm sitting on a cell phone on vibrate or something. This sensation lasts sometimes for a few seconds, sometimes for as much as a half hour, and has been going on now for 4 straight days. I also have had an intermittent aching pain in my left lower abdomen for the past 2 days. Also, 3 days ago, I experienced a shooting nerve sensation in both my legs that lasted for about two minutes...not painful, just like electricity running up and down my thighs. I have been checking regularly, and there are no noticable lesions.
Is it possible that this is some type of extended prodrome? From what I've read, a herpes prodrome can occur in both primary and recurrent infection, but only lasts for 2 hours to 2 days. I have never been tested for HSV, but I have never had an overt outbreak before, either.
Do these symptoms ever occur with primary herpes infections? And if it's not herpes, what else could it be?
