Thank you for the query.
Urinary tract infection
does not always give same symptoms and burning or pain while urinating does not have to be present. Frequent urinating and white floater
in your urine can indicate an infection. Blood does not have to be present in the urine to detect infection. It is more to be present white blood cells and bacteria in the urine. In case of any doubts, urine culture test should be done to choose good antibiotic.
Moreover, if this infections do recur from time to time, I suggest you to have checked your blood sugar level (diabetes
makes us prone to such infections) and consult urologist
to find out if there is no other reason in urinary tract (like narrow places, urine reflux, etc).
To improve your urinary tract, you should drink more mineral water and use cranberries supplements.
Hope this will help.
