Itching and burning after fingering?

This isn't my first time getting fingered, but it felt very very different since it hasn't happened since last September. It's been around three days since, and the feeling has lessened at night since I can now finally sleep, but now standing up is when the feelings comes back. There was pain urinating right after fingering but not anymore, it feels greater relive than I ever did whenever I urinated. My pee is also normal color. I looked down there, and there's little spots that are red as if they'd been torn. I know the body heals itself on it's own, and I hope it does. There was definitely no penis-vagina contact at all! I did feel this burning sensation as a child, when I got pushed into a bus' stick shift and that really made me feel like this, but it happened so long ago that I do not remember for how long. What can I do to help it heal or anything in mind, I don't think it's an STI or a yeast infection, but feel free to voice your opinion. Would Vaseline help at all?
