Greeneyes, you received great responses. I started with kidney/bladder problems when I was 13 years old. They were recurrent and extremely painful, and proceeded over a time period of a year. My Mother went to bat for me CONSTANTLY to try to get treatment, to which they finally stretched my urethra (put me under general anesthesia). This seemed to help for several years, but the bladder infections kept on returning at a rate of several per year. After I had my first child, I was in the ER 3 times with bleeding UTI's, put on antibiotics, given pain killers, and that seemed to help.
Just recently (over the past year and a half), I've been having SEVERE pain, UTI symptoms, etc., and was referred by my PCP to a Urologist. They took the above mentioned tests and even wanted to put me on Elmiron, but I'm researching that one right now. Some of the side effects I'm concerned with. I'm taking several meds right now, one Urelle and that helps more than the actual opoids. There are a variety of meds to take to help, and I could go into specifics, but you've been given good information by the others here.
Here is a link that describes the condition as well - web page
