/burning when I go to the toilet. I took a HIV test and it was negative, although the last time I had an encounter was 7 weeks ago and they said 12 weeks is needed to be sure.
I was wondering if it could be gonnorhea (Gonorrhea) without any discharge
I haven't any idea why they tested you for syphilis when syphilis wouldn't cause the symptoms you are describing, but its always good to know your status, so its not a waste.
I would follow up with gonorrhea, chlamydia, and urethritis testing if you are male.
