HELP (Vagina Pimples?)

I have no clue what it is. There is zero chance of HSV (like actually 0. No sex) There are these small white pimple looking bumps on my vagina lips. It kind of burns when I pee. It’s burning, like a rash. I did shave with an old razor a few weeks ago and had 1 ingrown hair bump. Then I shaved with a new razor a few days ago and this rash/folliculitis showed up. I’ve never had this before? What do I do to make it go away? I also started a new workout regime…
