Two hours ago I started having the urge to use the bathroom every five minutes. Nothing comes out though. My bladder feels full even though it isn't. I looked up the symptoms and it sounds like a UTI. I have been drinking water and cranberry juice. Does this last long? Am I doing the right thing? The needing to use the bathroom is really annoying, especially more sitting down. And I am really annoyed that I have it because I drink water all the time. I barely drink soda or anything else.
