i have had pain in the vaginal area for about 8 years. The pain comes and goes. It's relieved by eating yogourt, lots of water. I've gone to six doctors and they don't know what it could be. The pain varies but it seems worst at night. Its moe the upper vaginal area, i dont think its std's because i'm not sexually active. I think it could be an infection. I've had an ultrasound, blood test done and thye found nothing.
