Was HPV testing done with the pap? While it is possible for HSV 2 can cause a slightly abnormal pap, yes, the gyn and biopsy with colposcopy should definitely be able to sort out the different. It will be the lab test (biopsy) that will give you the real distinction about what is causing the abnormal pap.
Let me know how that goes, OK? I'll put my money on HPV, but we'll see.
