about 2.5 months ago I received oral from an escort. I was pee tested and all that came back clean. I never saw any kind of chancre on my genital. Now I am worried that I should go back and get tested for syph, because I have about 4 of what I first thought were in grown hairs on the back of my hand, but with bigger than usual red circles around. Then I have one on the back of my left hand, on one my right foot.
Does this sound like syph? Is it possible to have syph with a chancre?
