question: Hello doctor,  My mother had a urinary infection caused by Escherichia coli. She was treated with a 10 days course of Nitrofurantoin. The count of bacteria in her urine then was 500 hpf and 50 WBCs. Her symptoms were relieved. But after a week, she feels slight burning sensation now. During the infection period and now she has been having an urge to go to the toilet quite often and some irritation while passing the stools too. The stool is watery. We got her routine blood tests done and her WBC count in blood is slightly higher. She has no fever. Please advice.
