Two days ago, I was rushed to the local hospital with my first kidney stone. I am in good shape, non-smoker, drink very little alcohol, and work a physical job. The pain from the stone hasn't been as acute today, but now I have a 100.4 degree fever. My "average" body temperature is usually in the low 97 range. I have been screening my urine; nothing, and no blood. The stone is just over 2mm. What do I do now?
