Is it possible to get syphillis by having oral sex?
I found a lump on my vaginal area about a few months ago that kind of matches the description of a chancre, but I haven't experienced any other symptoms (i.e. burning, swelling, discharge,redness.) The lump is gone now, but there's a small area around my vagina that is slightly puffy, sort of like the way your skin looks right after you get a mosquito bite. The area is covered in a rough sort of covering, kind of dandruff/dead skin looking. Do I have an std?
