I'm 25 and not sexually active. After having a burning discomfort down there and lower back pains that my doctors were ignoring for weeks to months they finally did a test and discovered I had a UTI. I was put in Macrobid/ nitrofutonin 100mg 1 pill twice a day for 5 days. I took the medicine EXACTLY as prescribed. I was drinking both cranberry juice and water to flush it out completely. I did notice an immediate difference in the pain when I was taking the antibiotics. However, by the 4th day of treatment I noticed My infection stopped responding to the antibiotics. So I just assumed maybe it's residual burning and irritation from having a UTI for awhile. Plus I thought once I finish the course maybe it needed time to kick in so waited a few weeks to see if there would be difference.
So about 3-4 weeks later I decided to go back to the doctor to have my urine retested as the burning would come and go and was still causing me slight discomfort. My results came back today that I still have a UTI. Apparently it's the SAME bacteria from the first time. My lab culture says its "1,000-9,000 cocci gram positive isolated". I'm glad he bacteria hasn't grown back to the 10,000-50,000 amount I was seeing on my culture before after so many weeks. Why didn't the antibiotics kill off ALL of the bacteria? What do I do now? I know for a fact it's not a reinfection it's the SAME UTI that didn't fully clear up. I was still experiencing symptoms after i finished the course. Please help!
