Brian,
Thank you for your reply - the "confusion" w/ regard to idiopathic vs prediabetic comes about from the following. After the extensive blood, NCV, EMG, and MRI work-ups I had the 1st 2 neurologists concluded idiopathic. My FG is normal and OGT was 1 pt below prediabetic but I was "normal". I looked for a 3rd opinion and it wasn't until I got to UPenn and the neurologist there who agreed w/ me that 1 point higher for OGT would be prediabetic. Together w/ some other factors his diagnosis is prediabetic PN and is treating it as such - makes much more sense to me. Hope that clears things up - I realize this is somewhat convoluted.
We'll have to talk more since your experiences w/ prediabetic PN will be very helpful to me. I'm looking into water exercises for exactly the reasons you list. I did try oral B12 supplements for a few months but no shots. Maybe the time was too short.
Thanks again for your thoughts - what time is it in Australia now, early AM??
