Hi there follow up question;

Oh and I may have missed 1 or two doses of doxy due to getting vomiting it up

Test was an RPR test. Asked doctor for a treponial test and he seems to think nothing to worry about but also hasn’t seen new “lesion”

I also seem to have maybe a swollen groin lymph? It’s seems to be movable, hard ish bump on the right side right about waste line. I am larger so maybe fat deposit? Sometimes I can find and sometimes it takes a min to find, but I also have a diagnosed hydrocylee 

Figured I’d add details, to help..

The lesion also doesn’t seem to look like what google shows for syphilis chancre. I’d say it’s half the size of an eraser on inner thigh in a spot that rubs due to being overweight- no fever or anything

Welcome back to the Forum although I'm sorry you felt the need.  Your anxiety is showing - 6 posts in 15 minutes is excessive.  If you had reviewed our earlier interaction you will see that I said "If you had acquired syphilis, the doxycycline you took would not have "extended" the time needed to develop a positive syphilis test. Rather, if infection was present or developing, it would have cured syphilis." This is still true.  Nothing you describe comes anywhere close to describing a syphilis lesion and the location is not a place where syphilis regularly occurs.  In response to your specific questions---

Thanks doc. Yes stressing out, and online gives me different answers.. Especially around retesting after

And is RPR really the best test? Asking since I took test prior to a full 45 days

Sigh! I am always troubled by how often our clients are misled by the Internet. Please don’t use the Internet for health related information. You have no way of telling what is right and what is wrong and much of what is there is incorrect either because it is out of date, misinterpreted, taken out of context, or just repeating Urban myths ---
