Syphilis timing
Hi doc
I had two possible espouses with csw. One was unprotected oral and the other was a hand job. I tested for syphilis by rpr at 3.5 months after the first exposure and about ten weeks after the second, the test was negative. Although both exposures are low risk for syphilis both Csw were naked and were on top of me on both occasions. At 4.5 months after the first event and 3.5 after the second I had a lesion near my groin on my upper thigh near the crease of my leg and pubic area. I thought it was a pimple and popped it and blood came out. Over the next couple of days it formed a leasing that looks a bit like a chancre althought it is not deep just slightly pitted in the middle.
1. Is it possible to have a chancre so long after the exposure?
2. Is it possible to have a chancre in that area? Have you ever seen it in such a place?
3. Is my test valid or should I test again to make sure?

Oh good grief. If you have a symptom you are concerned about, see a health professional. It is a waste of time to be trying to figure it out on this forum or any other online source. All I can say is that the evidence is that whatever is going on is not due to syphilis caught during the sexual exposure you describe. In the meantime, re-read my replies above and concentrate on them.

I'm sorry to carry this on, but the sore looks incredibly similar to a chancre and there is zero pain. I understand how you think my 10 week test makes these questions irrelevant ( even though almost all other sources suggest 3 months) but the similarity is really disturbing. So in an effort to really rule this out in my head I would really appreciated a straight forward answer.
1) Is it possible or to your knowledge is it possible to develop a chancre post 90 days after exposure?
2) Although I understand having a extra genital chancre is rare, have you ever seen one in the groin area, near the pubic area clinically?

These are irrelevant questions. Your blood test proves you were not infected. Therefore, it doesn't matter what the risk was. You were not infected and do not need any further testing.
This thread is over. Accept the scientific evidence and reasoned reassurance you have had. I won't have any further comments.

hanks for your response. A couple of things still worry me though. The csw vagina did rub against my leg and groin. Wouldn't that put me at some kind of risk if she did have a sore? What is the most extended time period some one will develop a chancre? I've read both 90 days and 6 weeks?

Any time beyond 6 weeks is proof against syphilis.
I understand just for piece of my mind my rpr was given ten weeks from my last esposure not 3.5. Would that be valid?

Welcome to the forum.
First, an exposure like this is very unlikely to result in syphilis, assuming you're in the US or other industrialized countries -- where syphilis is a rare STD except in select groups. In the US, two thirds of cases are in gay men. But more important, your negative RPR at 3.5 months is proof you weren't infected; any genital sores or other symptoms that appeared afterward are not syphilis from the exposures you are concerned about. The direct answers to your questions are:
1) No, not possible.
2) Chancres occur only at the exact places of sexual contact; in your case, it would have to be the penis.
3) Your test is valid and no more testing is needed.
Most skin lesions in the area you describe are due to folliculitis or other localized bacterial infections. If the problem clears up in a few days, don't worry about it. If the problem continues or other lesions appear, see a health care provider. But don't worry about syphilis or any other STD. This problem almost certainly has nothing to do with your sexual exposures a few months back.
