Have you consulted a doctor, hurtloam? I had a bladder infection last month and didn't recognize the symptoms because I was focused on covid, but that tested negative. I had an ongoing fever and felt really crummy. Finally went in to urgent care, they diagnosed the bladder infection, a couple days later with antibiotics I was really much better (but finished the antibiotic anyway).
My point, at least call your doctor and ask the nurse what they think. It could be something that just gets better with medication?
