So, for the past few months or so, I'll have an occasional itch that really only is noticeable when I go to the bathroom. It's almost like a yeast infection but I've treated it with that and it didn't make it go away. And it's really only located in the vulva region. I was tested for STI back in March as part of my gyno exam and came back negative. I'm only sleeping with my boyfriend and he, likewise, is only with me. I am also fairly hygenic. The crazy part is it shows up for a few days then disappears for weeks. It's not a horrible itch but it's enough to be annoying. And it doesn't have discharge or odor. Any ideas?
