Any advice for a sensitive/itchy vulva?

Before anyone says go to the doctor - I have been! Time and time again. They never offer any assistance. It may sound weird, but I truly believe my cries are ignored because of my race. The inside of my lips nor my vagina itself itch, only the skin around (the vulva) this has been on going for YEARS. I have tried itch cream, changing underwear, better hygiene, fragrance free soaps, laundry detergent, etc. I am a virgin, so nothing is STD related. It gets more itchy towards my cycle. What are some more ways I can try to soothe the area? There is minor inflammation.

I can almost positively say that after years of research, this condition is ‘Vulvitis’.
