Sorry I didn't state that my PN was due to diabetes. The symptoms actually started before diagnosed with diabetes and progressed as you mentioned. Now numb up to my knees, as well as finger tips. My diabetes is under control with medication. Pain from PN subsided after a couple of years and I was left with only the progressive numbness. Now, the imbalance is a new dilemma that I am trying to obtain a correct diagnosis for. Thanks for your comments.
