My sore feet and numbness has progressed to small areas of numbness and burning on my hands. These tend to move around and are really causing me a lot of anxiety.

I am 178cm (5'11") and 80kg (177lb) a solid build but not overweight, my wife's description and she is a health professional. I eat reasonably healthy apart from my big sweet tooth; I eat a fair bit of ice cream, chocolate and/or lollies (candy) most days. The only reason I have gotten away with this is because of my level of exercise.

I am wondering if my diet could be contributing to my problem or if I could be pre-diabetic?
