I am single and virgin I don't know how e coli had affected me from one year I am having abdominal pain and frequent urination problem and some tym pain in back because of kidney stones. I had course of medicine but due to lockdown I am not able to consult my doc he had given me nifty sr tablets but after taking that I feel nausea and vomiting than I had stopped that pill only after one dose Please suggest me medication for cystitis and kidney stones. Or please tell me the correct way of taking nifty sr .
