White Streaks on Labia: Yeast Infection or Something Else?

Might be TMI: For about 2 months now, I have had white streaks on my labia. At first, they weren't causing me any issues, and I didn't have any insurance due to moving. After developing symptoms such as itching and thick white vaginal discharge, i decided to go to the doctor. I was diagnosed with a yeast infection that turned out to be very stubborn. After multiple rounds of Monistat and a prescription for Fluconazole, I feel like I'm finally getting relief from the yeast infection. Except, the white stripes are still on my labia. They started to fade on the medication but keep coming back. They're white and look like the skin is kind of raised. They also itch sometimes. I read about a couple of different things it could be, and I wanted to get someone else's opinion. Am I going to be stuck with white striped on my labia or is it a stubborn yeast infection that still hasn't cleared up? If it's not a yeast infection, what could it be?
