Can it be? Syphillis?

[wonder2345]

I'm a woman in my early 40s and I was seperated from husband. During seperation, I was involved with a male and had unprotected intercourse/vaginal only  with no ejaculation inside on 7/30/09 n oral with ejaculation/spit n rinsed mouth on 8/23/09. I tested @ 5 months post exposure for hiv and syphillis-negative and @ 6 month mark for hiv, syphillis, chlamydia and gonnorhea and was negative. My concern is that in Nov.2009 I had a ear infection and was given Bactrim.  I took it for only a few days and then was given Tamiflu because I developed the flu. Come to find out it wasn't the flu but an allergic reaction to Bactrim. Could the drugs that I took have masked a syphillis infection causin me to have a false negative?  I'm having symptoms: hair loss, a cut near my anus which I thought was from cleaning myself too hard with toliet paper. The cut is still there but its healing...I've had the cut for like 3-4 weeks. I have since reconciled with my husband and am petrified that my tests were all wrong. Btw I do have hsv2 and I did disclose to my fomer partner. I also insisted that he be tested foe all stds prior to our engaging. He said he tested and was negative but I never did see the actual results. Only saw his last rapid hiv test which he took on 8/29/09-negative and 6 months from his last sexual encounter. Should I retest?  I'm at my wits end.

Hi

"Could the drugs that I took have masked a syphillis infection causin me to have a false negative? "
              NO

"should I retest?"
              You should NOT retest for any STD.

You are not at your wits end.  Guilt has played a tremendous role in how you are feeling; you even confessed to your husband of your doings, which probably will help with all this
un needed anxiety, guilt, and worry.   You should move on with your life about that encounter.
