I too am currently suffering from kidney pain. As a matter of fact, later today, I've been scheduled for a CatScan to see what the problem is now.
But in reading your post, I feel that if you haven't done so already, go to the Emergency Room! You need to be seen as soon as possible. Believe me when I tell you that I know the pain your little kidney can produce can be debilitating. I swear, I've had two kids and the times I've experienced kidney pain was WORSE than childbirth. Anyway, back to my point, you're obviously no better than you were earlier, so lines or not, get seen by the E.R. And, you might be seen earlier than some because of your acuteness of your pain. Don't mess around with this kind of condition.
Good luck, I'll be sending you positive thoughts . . .
