Thank you for choosing DoctorSpring.
I have discussed your concern with our Dermatologist.
Will it be possible for you to upload a picture of the lesion ? You can upload it here or email it to email@example.com
The emailed pictures were not available, please check your email again. I am really sorry and I am trying to get this issue sorted out asap. But please bear with me and send them in email by uploading/attaching rather than copy paste in the body.

I just rechecked RPR again,done last night, its read negative.
Thanks for posting your query at DoctorSpring.com. I can understand your concern.
RPR test shows dropping levels of antibodies after treatment.
The picture shows a macular localized rash which can be seen in secondary syphilis. However, this rash is not specific for syphilis. You could send me a few more pictures of the rash? even a few zoomed out ones.
RPR test rises in presence of infection, however in early stages it may not be positive.
Its not wise to recommend retreatment, just on the basis of the rash. There should be confirmation of reinfection with blood tests, e g. RPR levels should rise indicating infection.
I would recommend that you need to visit your doctor for further evaluation.
Hope this helps, please feel free to discuss further.
