I've been having symptoms of kidney infection for the past few days. Bad lower back pain, fever, nausea, etc. I can't go to the doctor for a few more days, my clinic is pretty busy and isn't open til tomorrow anyway. I was just wondering how long does it usually take to cause damage or turn into sepsis? I have had sepsis before but I don't remember much from them because I also had mono and an infection so was out of it. Any help is appreciated.
