possible herpes infection?

[noctambule]

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?

While some of those symptoms can be associated with genital herpes, in general that is only when there are typical genital herpes lesions.  That is, occurring by themselves, your symptoms do not suggest herpes.  I could change that opinion if in the next few days you develop overt genital blisters, sores, etc, which can take as long as 2-3 weeks to show up.  But I don't think that will happen.  In any case, condoms are highly protective against herpes--not perfect, but very good.

I really cannot speculate on other causes.  My main advice is to see a health care provider if they persist or if you remain concerned.  In the meantime, you could also speak with your partner about whether he has herpes.  If he says no, he still could have it--but it would still be reassuring to know he doesn't believe he is infected.

Good luck--  HHH, MD

Sorry, I forgot to mention syphilis.  It's not a risk; both Rocephin and doxycycline are effective in prevention.

I did get an HSV test yesterday, because I've never had one before, but I realize this probably won't tell me if I've been recently infected.

But I'm still a little confused about this prodrome thing.  I didn't think it was supposed to last this long.  How long can these symptoms go before I can feel somewhat reassured that it's something else, and not a herpes prodrome?

[H. Hunter Handsfield, M.D.]

You're right about the duration of prodrome.  That's one of the main reasons I don't think you have herpes.
