Hello and welcome,
Thanks for your query.
Although you report an increased urge to urinate, this might not be sufficient to make a diagnosis of a UTI.
The most common symptoms of a UTI are the following:
-Increased frequency of urination
-Burning sensation while urinating
Although not all symptoms might be present, a diagnosis is made with the help of a urine analysis.
This investigation will help in establishing whether or not you have an infection.
Along with a urine analysis a urine culture should also be done, as it helps in providing the doctor with information on the type of treatment. A urine culture will help in finding out which antibiotic would best suit you to cure you off the infection.
It could be possible that you are resistant to the antibiotic you are using, which means it will not help you. Thus, a urine culture would show us which antibiotic would best treat your infection.
I hope I have succeeded in answering your questions, you could write back to us anytime for further clarifications.
