What Do I Have?

I don't have cancer, but I don't know where else to post.  I am experiencing uncomfort "down there".  Actually, I had a bladder infection, and was treated for it, but before that, a yeast infection i was treated for. It seems that the infections never go away, I'm still not really sure if the yeast infection ever did. But now I am noticing little white bumps on the inside of the lips of my vagina. They kind of hurt and they itch sometimes. Also, I noticed what looked like 2 blisters, or pimples. I really need to know what this is and how to get rid of it! I'm not sexually active, so it can't be an STD. Please help, this is driving me crazy! Thanks
