in August 2017 I had an oral presentation with a sex worker, it was fast and after we had vaginal sex with a condom, I think I had some symptoms. One month ago I had some acnes in my chest and in a few days I had two little wounds in the my elbows, can it be syphilis ??? 8 months ago, no fever or swollen lymph nodes, I'm very nervous and anxious, please respond!
