I have a bladder infection that doesn't seem to want to go away. I've been on two rounds of different anti-biotics and I still am having symptoms. I'm so annoyed. I've been dealing with this for two months now. I'm on Detrol La. They say it takes Detrol a couple of weeks to work. There are days when I'm OK. And there are days when it's horrible. I don't know what is going on.
