About 2 weeks ago, I developed the worst yeast infection I've ever had in my life a day after being sexually active with my gf for the second time. I also developed 2 white patches on opposite sides of the labia (facing each other). They are not painful, nor itchy, nor raised above the skin. I assumed this was thrust and went ahead with the yeast infection treatment. The infection has cleared up, and the white patches have diminished in size, and are not as bright white as they had been, but they're still there. Is there another explanation for why they're still present, or do I need a separate treatment for them?
