Hi Shawn, I have had CIN3(2004) and just had surgery for VIN2/3. Both were caused by the HPV virus, that I didn't even know I had for sure until this year. I had discomfort/pain during and after sex for a couple days. I continued to dismiss this, as it always seemed to get better.
This went on for a year. (this is the short story
) I went for my yearly smear, and mentioned to Dr (at womens clinic) what had been happening. She really couldn't tell what might be the problem (lots of guesses) and referred me to a Dermatologist (Skin and Cancer clinic). She did a biopsy of the area on my vulva that was sensitive. It came back VIN2/3. She referred me to a Gynae Oncologist. He did a wide local excision, two biopsies and a colposcopy to recheck my cervix.
The moral of my story is, make sure you see someone that knows what they are looking at. If you have worries, don't brush over them, its always better to be safe than sorry. As for what you have explained, i don't think I can remark on it, or even take a guess. Only you know what is normal for you.
VIN is even rarer than CIN, and it is very sneaky. Some women don't even realise till its too late. The reason I'm saying that is that I really want all women who have or not had CIN to get to know there vulva. Any change at all must and should be checked.
Good luck. Hope everything is ok, and sorry if I have worried you more. But knowledge is power.
