To add to what Big Dave says, it is possible to suffer from diabetic type peripheral neuropathy despite one's fasting blood sugar levels and A1C being well below the thresholds normally associated with type 2 diabetes. It seems that all that may be required in some cases is reduced glucose tolerance (which can also be tested for) which can allow damaging blood sugar levels in the short term even though fasting and average levels are normal. My own problems of this type also predate my use of PM, and don't seem to have been noticeably influenced by it. Nor can I say whether PM has worsened my backaches. Any recent worsening is more probably due to my ventral hernia. With many other factors at play, it is very difficult to know what causes what.
