Thanks for the thanks. Happy fourth.
Thank you again doctor. I cannot tell you how much I refer to you and your site for guidance. It is very much appreciated.
With this more detailed explanation, I am doubtful this new lesion is a herpes outbreak of any kind. If it were, I would expect it to promptly (within a day or two) turn into a blister then to ulcerate, which is probably how your chronic oral herpes behaves. I would also expect more than one lesion. If it doesn't progess in this fashion, probably nothing need be done. There's no point in a PCR or culture for HSV unless the lesion becomes a blister or an open ulcer.
Thank you so much for the extensive response. I never expected a response on the holiday. I appreciate it. It's been about 12 hours since I noticed what I thought was the start of the cold sore. It hasn't manifested yet. It felt like a bump under the skin at the corner of my mouth but now I'm not sure. There is no blister yet...no fluid...just what may be a slight bump. Last night it looked red, now it doesn't. When I've had them in the past, I believe they appeared quickly. My sore throat is pretty much gone but my one gland under my neck is slightly swollen. As a general rule though I regulalry get swollen glands...have my whole life. I'm not opposed to testing at all. I'm just confused. When I wrote you, I really thought I had the start of a cold sore.
How long would it take it to turn blister-like if it is HSV2? If it doesn't, should I still be concerned? There's nothing really visible to show a doctor at this point. The slight bump is under the skin. If it doesn't transpire to be anything more, do you think I still need to be checked?
Welcome to the forum. Thanks for your question.
I don't agree your decision to have mutual oral sex with a partner with known genital HSV-2 was necessarily a "poor choice" and you shouldn't beat yourself over the head with it. As you seem to understand (at an intellectual level if not emotionally) it was a low risk exposure.
That said, I cannot guarantee you don't have a new oral HSV-2 infection. Given the timing of your new cold sore and its new location compared with your earlier oral HSV-1 outbreaks, and the association with sore throat, I agree it would be wise for you to be examined and tested for oral HSV-2. I recommend you visit a doctor or clinic ASAP (maybe difficult today, July 4, assuming you're in the US); or tomorrow for sure. The point is to have a swab of your new cold sore and perhaps your throat for testing for HSV-2, preferably by PCR -- although culture would be OK if that's the only test offered by your doctor or clinic. You also could have a blood test, as a baseline: if the PCR or culture don't show HSV-2, then you could have a second blood test in several weeks to see if there is any change.
To your specific questions:
1) Cold sore location isn't set in stone. As noted above, this could be a clue to a new HSV infection, but most likely it's your old one despite the location. If your PCR/culture is positive for HSV-1, it will confirm it's just an atypical recurrence.
2) Autoinoculation (self infection of new body parts) is theoretically possible but very rare. As a common sense approach, I would advise you to wash your hands before using the toilet, in case you have (unconsiously) recently touched the cold sore. But even if you forget, the chance is exceedingly low.
3) Passive transfer of his virus to your genital area by this mechanism would be very rare as well. No worries.
4,5) As noted above, I believe you should be tested. Most gynecologists and dermatologists should be up to speed on the necessary tests, but so are many internists and family medicine doctors; or your local health department STD clinic (although many don't have direct HSV testing available); or a Planned Parenthood clinic. I suggest you call ahead to see whether the tests I have recommended are available.
6) Absence of sores inside may be slightly reassuring, but nonprimary initial infections can be very mild; and you do have sore throat. This doesn't influence my opinioin one way or the other.
7) You are a better judge than I can be of the likelihood you are in the early stage of a herpes outbreak. If it is behaving like your previous cold sores, that's enough for me to be suspicious.
8, below) I suggest crossing this bridge if and when you come to it. However, i indeed you turn out to now have oral HSV-2, you can assume that in the future you will be highly resistant -- perhaps completely immune -- to yet another HSV-2 infection anywhere on your body.
I hope this has helped. Thanks again for an interesting question. I'll be interested in hearing how it all shakes out after you have been examined and tested.
Best wishes-- HHH, MD
...and I forgot to ask...8) If I do have HSV2 orally, how protected am I from getting it genitally if I begin having vaginal sex? I know it provides protection, but is it 100% and how long does it take the antibodies to build up to have this protection.
Thank you again.
