I don't drink water much. And due to using public toilets, I catch urinary infection once in an year. While peeing, when the bladder gets empty, it burns. I also had severe pain last night in right kidney. The back was paining specifically. I took pain killer injection then. I have gone through Routine and Culture tests today. As per routine's reports, pus cells are 10-12 ans Leucocyte Esterase is positive. Please suggest, if it's a severe infection or can be cured by antibiotics.
