I found out because of this I have olsers on my uteris and bladder and very painful. Two years ago I kept having uti with blood and pus this recquired medication for a year it the UTI never whent away a culture was done but did not show any blood in urine. In March I found out by a GYN that I have olsers on bladder and Utiis wall and perhaps on the outside. I was unalbe to take the Medication and have yet to make it back to the Doctor. I am in pain most of the time and go to the restroom alot and before bed it is as if I can not eleminate all my bladder. I had an ablation in July of 2006 and surgery on uetha because of removal of a tumor benine.
