Concerned About Possible Chancre

by professor101, Aug 17, 2006 12:00AM
About a month ago, I had unprotected oral sex with a woman (giving and receiving).  

Around a week ago, a small, slightly-painful-to-the-touch, dry, red sore developed on my right ankle.  (My shoes are comfortable, so I don't imagine that it's a blister gone bad.)

Around the same time, the right lymph node of my groin got infected.  

Is it possible to even have a chancre on the ankle, a part of my body that was in no way involved with sex?

No chance.  Chancres do not occur away from the sites of direct exposure.  If there was no direct contact of your ankle with your partner's genitals or mouth, it's not a chancre.  Anyway, with only a few exceptions, syphilis is extremely rare in heterosexual men and women in the US.

Any inflammation anywhere on the leg or foot will cause lymph node inflammation in the groin.  Some are serious, especially staph and strep.  You need to see a health care provider.  Do it immediately--and I mean immediately, even if middle of the night--if you develop fever, if you develop rapidly expanding redness around the ankle lesion, if you have a red streak running up your leg, or if the lymph node continues to enlarge.

But don't worry about syphilis or any other STD.

Good luck-- HHH, MD
