Dear Doctor,
I have read through all of the forums and I am about 98% sure that I cannot have syphilis -- I am aware that the risk was extremely minimal. No need to repeat yourself regarding this aspect.
The situation: brief (20-30 seconds) unprotected oral, receiving, I am a man, received from a woman with no visible oral outbreaks, exacty 27 days ago.
Next day I began taking Clarithro (unrelated infection), 3.5 grams over the course of 5 days. On two of those days I took 2 pills, i.e. 1g, taken at once. Two days after starting the Biaxin I was prescribed doxycycline, 2g total taken over the course of 7 days.
On day 8 after swimming I noticed what looked like a skin fold on the end of my penis next to the urethral opening (about 1/8 inch). Unsure whether this was something normal for my penis or not, I have been observing it since. It is not an open sore or a blister, it is not red, and it is painless. Sometimes it is only clearly visible in certain light.
It has not changed its form in 19 days. It looks like a tiny "11", raised slightly, whiter than the surrounding tissue. I have always had a few whitish areas on my glans penis (not raised). I have noticed other similar "lines" on my penis at times, and I think they look like rows of those tiny, benign papules (I believe this is the term) that can be part of normal anatomy. Add to this that I tend toward benign cyst formation in other parts of my skin.
Questions:
1) I know that without looking, you can't really know, but: does this sound anything like a syphilis chancre, and if so, is it possible that the syphilis chancre would show up just 8 days after a potential exposure?
2) What would the approximate percent chance be that the medications would not have cured syphilis in its incubation phase?
Thank you in advance, doctor. I just need to fill in my remaining 2% of uncertainty.
I said I would keep it brief. If it got too long-winded, it's only in the interest of accuracy.
Cheers
