RISK:Im a female…. Had unprotected sex with a heterosexual guy 4 times and gave him oral too…
Few weeks later, i had a painless clear fluid filled blister/bump on the inside of my lower lip. I popped it, and clear fluid came out but then after few days, it came back again at the same spot….I popped it again, a week or few weeks later it disappeared…
Can this be a chancre (syphilis)?
