I finally got my kiss-off letter from Kaiser. They basically just restated my entire complaint (replacing "I" with "you") and told me that I should consider going to hell. Which is exactly what I figured they would do. They did say they talked to the rheumatologist in question about it. If nothing else that means she knows that I think she's a useless waste of space. They also said I can get a second opinion if I want. As if I wasn't going to, anyway!
My next step is to get an appointment with another doctor, and to tell them in no uncertain terms what they need to do. Unfortunately, I am no longer willing to make these visits without someone else accompanying me as witness, and until my husband's job calms down enough that he can take an afternoon off without being yelled at for the next solid week I am out of luck.
For now I am just going to go jitter quietly in the corner for a few hours to work off this desperate adrenaline surge.
