Just got calls from both my doctor and the hospital - seems the tests they took at ER on Friday are showing I DO have a small kidney infection! Gee, why didn't I think of that.
Since it is happening all too often they are putting me on a short (3 day) course of IV anti-biotic which I start this afternoon.
When my GP called me I told her how the ER doctor treated me and she was furious. She is going to look into it further. He was diagnosing my file, not me. He saw chronic back pain and wouldn't look further to see there was something "underneath" and to trust that I know the difference.
I feel better already!
