Hi & welcome to the forum, there are many courses of Neuropathy as Mrs D mentioned, i know some friends of mine that have been long term Diabetics but do not have any signs of Neuropathy, but some have suffered other very serious complications as a result of high blood sugars, then there are others like me that were only in a prediabetic state [who knows for how long] but get peripheral nerve damage and no other problems.
Besides the many other possibilities causing your nerve damage , i am wondering
how well are you managing your sugar levels ? & do you drink alcohol ? as this can aggravate your nerves as well as others like stress, etc, please tell us more.
