While I don't know a great deal about neuropathy (I am mainly learning from this forum and its links), I do agree that a GTT would be a good idea if you haven't had one before. It's not pricey, it's not invasive, and if it's negative, you can say you have ruled out diabetes.

When I went to an endocinologist for a goiter, she suggested a GTT pretty much as an afterthought. Surprise! We found out I was diabetic in addition to hypothyroid.

While it can be frustrating to not know what you have, it can be quite helpful to know what you DON'T have.

Good luck on your quest to find a neuro with a brain.
