Just about every time I have sex there is a burning sensation and then a day or two later I develop small white patches near the opening of my vagina that turn to ulcers. I had both a blood and swab test for herpes and it came back negative. I've also been treated with oral antibiotics for BV and Strep b yet the problem has persisted. I have a new doctor that I'll be seeing Tuesday and she is planning to do a DNA test but I've already seen 4 other doctors who can't seek to figure out what this. Also, I can't seem to find anything online that matches my symptoms. Herpes never even matched up - we just tested because we didn't know what else it could be. BV seems to make sense except that these ulcers don't seem to be a symptom of it according to sites like the mayo clinic. Strep b info is so scant that I really don't know if that could be it or not. I did a test for Chlamydia BEFORE all this started and it was negative (I was pregnant so it was standard procedure) but now I'm wondering if I should have another test...Anyhow, any insight would be appreciated!
