I Used Nair The Hair Removal Product Several Times On

I used Nair the hair removal product several times on my vagina, never had a problem. Used it Wednesday and it burnt the lips of my vagina. Did nothing but keep it clean a couple of day, spoke with friends to see if it has happened to them. Used the products triple antibiotic and aquaphor, it helped, but its petroleum jelly based which makes the vaginal area itch. The burn has healed in several areas now I have white bumps and under the skin bumps. Really painful after bath time. What to do or use? Please Help.
