my mom has uti for for 1 week then she took antibiotic for 7days and it was gone, then after how many days it came back again, had her urinalysis checked again it was too numerous to count once again, now she's taking uritracin 400 mg as per the doctor it should be for two weeks, but its 6th days now her urine is sometimes clear and sometimes cloudy early in the morning when she pee, why is that so? is there something wrong inside?
