Hi, I got PN first. I went through three doctors before getting help.

I had trouble convincing the third doctor to give me a GTT because my fasting glucose was normal. The GTT was positive. The neurologist I went to then blew me off.

I also went to a nephrologist because the protein in my urine was high. The nephrologist is checking more blood tests for types of PN that increase protein in urine. He doesn't think I have nephropathy(of the kidneys), but ordered an ultrasound and more urine tests for damaged kidneys.

According to the tests so far the only thing my PN could be is diabetic related. I am already thin, so I have just been on a strict diet, and using the treadmill.

You should definitely get a GTT because my fasting glucose was normal like yours. However no one diagnosed me yet with diabetic neuropathy based on the GTT. Bring information to your doctor and get it.
