Diabetic Neuropathy (Nerve Damage)
 

Another good write-up from Everyday Health. This one gives full details about Diabetic Neuropathy. This is far more common than Diabetic Nephropathy, luckily most cases are relatively mild. Don't become nonchalant about it, though, because it is the most common cause of non-traumatic amputations.
