I recieved an unprotected handjob from a prostitiute 15 weeks ago. I experienced a generalized rash all over my body at 6 weeks, but test negative at 7.5 weeks. I now have rash on palms of hands, sweaty palms, constipation, fatigue, and firm bump on my penis, very dry skin, and the top of my finger nail beds look like red arches and the bottom of them are white. I am freaking out that i got syphilis from this *********e or even HIV. How accurate is my 7.5 week test for HIV and what are the chances i have syphilis from a handjob? thanks.
