I have now had burning and soreness of the vulva and vaginal area for over six months, and I was tested for everything you could imagine as well as herpes. After every test came back negative, I was finally diagnosed with Vulvodynia and Vulvar Vestibulitis. Please look both of these conditions up, as just because you have previously had a diagnosis of herpes, it does not mean that your symptoms are due to it. I find it hard to believe that it would be a reaction caused by HSV and lasted so long. Not alot of Gyne docs are aware of the conditions, so they are often dismissed as easily as they are brought up. I hope that you are able to pin point your pain and alleviate it soon!
I do know Herpes can cause some odd sensations in and around the affected area even when no outbreak is present but it shouldn't be anything very severe I would be inclined to pursue this incase there is pelvic inflammation that needs treated .....
