I have kidney stones for past 2year. I have passed two stones of 8 mm and 6mm on both the sides each. After that my ultrasound result(August2018) shows three more stones of 5mm each. But by my doctor's advice I undergone CT scan(August 2018) which shows nill stones. So my doctor adviced me to drink plenty of water and no further medicines. But Now (October) my left side stomach is paining like a kidney stone pain. Is that possible of forming of stone within one and half month ??? Orelse what could be this pain ???
