Since the last post - I met with a dermatologist who was immediately certain what the lesion was. Biopsy showed it was Lichenoid Dermatitis with a negative Syphillis infection stain. This was all very reassuring. Since then I was tested again while traveling and had a negative Treponema Pallidum Ab CLIA on 10/27 (4 months since exposure). Again re-assuring.

Yesterday, I received another blood test from my home clinic - to check both RPR level since August and do a full panel. I have had no sexual encounters in the last 6 months. The RPR came back 1:16. This is shocking given that the last RPRs have gone: 1:4, 1:2, 1:4. I am waiting on the results of the treponomal test but my expectations (hope?) are that it is will be negative. I will report the results here but hoping to get this thread started as I am leaving for travel on Friday, 12/26.

1. What is going on here? Should I be concerned that my RPR is up 1:16? The 4x increase has freaked me out.
2. I had a cold about 4 weeks ago that I caught at a wedding - sinus pressure, one day of fever, and cough after recovering. I wasn't able to test for covid - however, multiple other people also caught the same thing. Could this cause the elevated RPR levels?

3. How should I approach my trip/traveling? I'm concerned if a condition is getting worse.

Thanks again
