Hi, your symptoms are not the usual symptoms caused by prediabetes or diabetes, the most distal extremities are affected first [feet], burning, tingling and sharp jabbing feelings then over time it can creep up the legs and then the hands are affected.
My neuropathy was caused by prediabetes which has completely resolved these days but took a few years to heal fully.

By the way some people can have normal fasting levels even when a person is diabetic, a 3 to 5 hour glucose tolerance test is a very good test to see how your body reacts to sugar, plus insulin levels should be taken through out the test.
A glucose monitor is very helpful to evaluate what and how much foods affect your sugars, if you take a reading 2 hours after the first bite of a meal, then it is easy to work out how much you can have of different foods without spiking.

I do hope you can find the culprit causing your symptoms.
good luck
Brian
