Hello, sorry I didn't get back. I believe what I have is urinary track infection. It's gotten a lot better, I've been drinking apple cider vinegar with some baking soda and water, as well as drinking lots of water, avoiding dairy, and of course praying.
Even though I had that lower back ache for a day, I never really believed it was a problem in my kidneys, but I also wasn't sure, which is why I originally posted this in the General Q&A, but it was quickly moved here because it seemed a moderator in his/her expert medical opinion, diagnosed it as a Kidney problem and put it here.
So yeah, while the problem still persists slightly, It's improved dramatically since I started doing what I mentioned earlier. I haven't gone to a doctor, but I don't have health insurance and money's too tight for me to go to one.
