I Burned The Outer Skin Of My Vulva From Nair

I burned the outer skin of my vulva from nair & it's burning & painful also when I urinate, it burns my vagina lips.. I had just exfoliated with warm water & I'm guessing my pores were open because this wasn't my first time, as I've used nair to remove pubic hair many times before. As soon as I applied the nair it immediately started burning, & I immediately started to rinse it off. I then used soap wash it off but it burned more then I applied apple cider vinegar which made it burn A MILLION times more & I rinsed that off as well. But the burning sensation happens whenever the skin touches underwear, toilet tissue or urine. Help me please ??
