I have been suffering from low grade fever(99.5-101F) for more than two weeks. I had severe pain once in my left abdominal almost 20days back. I was then told that I had stone and infection. Since then I was taking high antibiotics. The fever started after few days of taking the medicine. The recent urine report said its clear. Last night, I felt the stone probably passed out. But I still have the fever. is it for infection or the medicine? I am really worried.
