How would I know if I have a infection sepsis? I do have kidney stones and the Hi, I would like to know if I have a sepsis infection. I do have kidney stones, 2 have passed, but there is one stuck in the kidney. I am running a fever(101) and do have considerable pain in my back and side. My urine is the color of cranberry juice. This has gone on since July 22nd. The ER doc recommended immediate surgery, but my primary and urologist do not seem concerned. I am scheduled for surgery next week (Wed.), but I am weak and in pain.
