Yes, I think you can put it to rest.
Did a doctor ever see the sore? A syphilis chancre clearing in 10 days is possible, but that's pretty fast for it to clear.
Thanks for your reply!
A physician assistant saw it and said it didn't look like the chancres he'd ever seen before but that he couldn't rule it out (he also said he had only seen about four of them before). It had cleared up by the time the nurse at the STD clinic saw me.
I've asked Dr. Hook about it over at ASHA and he seems to think the 9 week tests are conclusive. I'm still really concerned because the first time I ever have an exposure like this this (with a csw) I get a sore on my penis and lymph node pains in my groin. Seems like such a coincidence. I'm wondering about testing again at 12 weeks. Have you ever seen or heard of someone testing positive at 12 weeks after being negative at 9 weeks? Thanks again.
