I felt I needed to contribute to this thread just a little - While I was having my EMG tests done a couple of weeks ago, the technician was constantly remarking (mostly to the student observing the testing, but to me as well) about how responsive my nerves were and how that's a significant problem in general - they don't have any honest individual baselines. He was saying that in 20 years when and if my neuro response levels drop to "merely normal" they'd say that everything is fine, except that *my* normal response is much higher than the statistical average. So I could be feeling significant neuromuscular deficiency but if I'm within "normal" response would not be diagnosed with any loss. That could very well be what is happening to Sonja... her "normal" could be quite beyond statistical normal and so she's feeling the effects but cannot convince her doctor of what the problem is.

Best wishes for you and hope you get well treated...
