I wake up almost every morning "vibrating." The way I describe it is that I feel like I'm plugged into an electrical socket and have a low level electrical current running through my body. Usually though, as soon as I get up or start moving around, it subsides. Other symptoms crop up as the day moves on.

High blood glucose is a known and common source of nerve damage. 60% to 70% of all diabetics have some level of neuropathy. Unless you've taken the Oral Glucose Tolerance Test and know for an absolute fact that you have zero glucose issues, I can't imagine having neuropathy from ANY source and not trying to watch carb intake.

This is a good read, especially the case studies mentioned. I'm not saying this is your problem, but this is why the OGTT is so important for anyone with neuropathic symptoms. One of the major, well-renowned hospital websites (can't remember which one) says it should be a standard part of any neuropathic work-up.

"The cause of polyneuropathy remains unknown in more than 20% of cases despite extensive laboratory testing. The incidence of idiopathic cases is believed to be even higher among patients presenting with painful sensory neuropathy. However, some patients with “idiopathic” painful sensory neuropathy have ultimately developed overt diabetes mellitus after many years of follow-up, suggesting that occult impairment of glucose metabolism may have been the cause of their symptoms all along. There have been a number of recent series suggesting than more than 50% of the patients referred to neuromuscular clinics with a diagnosis of “idiopathic” painful sensory neuropathy have abnormal glucose metabolism when they are evaluated using the 2-hour glucose tolerance test (Table 3). Of these, more than 50% have impaired glucose tolerance, so the fasting glucose and glycohemoglobin are frequently normal despite an abnormal glucose tolerance test. These incidences of occult diabetes and impaired glucose tolerance are significantly higher than those reported for the general population, suggesting a causal relationship."
