PN diagnosed some years ago now with previous experience of a numbness developing over some 20 years ago starting with the ends of the big toe and other toes in turn, developing into the feet over time. However diabetes has not been diagnosed despite being checked regularly as a result of sight loss issues. I was advised that I was prediabetic at an early stage and moderated my diet along the low carb diet message. Whilst the PN issues have not reversed they are manageable.
