Hi Sunnysky.
I began to develop neuropathy around 2014 when my HbA1c was about 43. This was only one of a number of diabetic symptoms - I was developing new stuff all the time - kidney problems, weight gain, oedema, and more. I was firmly told that I wasn't diabetic, as my BG wasn't high enough, and therefore it couldn't be diabetic neuropathy. But it was.
I wasn't surprised I had it. I was surprised that none of the GPs I saw over a period of getting on ten years with a range of classic T2 diabetic symptoms ever suggested it was in fact T2. Dr Google had already stated T2, and I mentioned this to the GP, to receive the "your blood glucose isn't high enough" reply. Dr Google's alternative idea was cancer....
Once I was finally told I actually had T2, (HbA1c of 50) I started low carb straight away and went to 20g/day. No medication. The worst of the neuropathy was gone in four months as my A1c fell to 36. I have some permanent damage in the form of a mild tingle, but it's neither painful nor annoying.
The NHS' own handbook says that around 20% newly diagnosed people with T2 already have evidence of vascular complications, which suggests that complications begin 5-6 years before diagnosis is made. In my view this is a consequence of the decision only to diagnose T2 at "A1c of >48" which means that there are going to be a fair number of people who actually have diabetes - symptoms etc - at lower BG levels and who are not being picked up for treatment. The "diagnosis at 48" is not good for patients.
