Good evening......I have experienced UTI incidents frequently over,the past 5 years. I have had multiple urine tests and standard treatment of bactrim or cyproflaxin has usually brought the situations at bay. Now I have a slight burn about 45 to 60 seconds after urination that lasts about 20 t0 30 seconds. My PSA has been tested several times with the results showing a 4.7 results. My urologists has ultra sounded for bladder tumors and I am clear. My PH tests for acidity show only a slight acid condition. My urine odor is normally a chestnut aroma with an occasional fishy odor. I am 69 yoa male. Been trying home remedies with marginal results. Any help would be appreciated.
