Help needed asap

Hi ladies

My lady parts are extremely itchy. The itchiness starts from mons pubis and goes down to clitoral hood, clitoris, labia and vulva. This itch gets worst at night, i dint have painful sex or pain going to bathroom.

I can see a weird line that starts from the clitoral hood and it goes down on to the right side of the vulva.

Does anyone know what the heck this is because the itch is going to make me crazy! it is that bad. I booked an appointment for it however its a month from now and i dont think i can make it that long..
