that's so annoying when docs think it's just in your head.Neuropathy would be my first guess, too! That is exactly how mine began 14 years ago. And while I agree that "tight blood sugar control" is important, it doesn't stop neuropathy. At the most, it will slow it down.
My sugars have always been extremely tight. Until about 16 months, when they moved to me both fast acting and long acting insulin, and I still had what my neurologist termed as rapid onset neuropathy. In other words, once it took iIt took off like a just leaving the municipal airport.
Richard is correct in telling you that only nerve conduction tests can identify the culprit, but, in my case it took nearly four years (after the burning, electrical shock sensations, and pain) of tests to identify the neuropathy.
During that time, my Workers Comp Insurance company and doctors tried to claim it was all in my head. In one they were correct. Neuropathy is in the head, as it is the brain that receives the message from those nerve endings (on the top, bottom and sides) in the feet that tell the brain what kind of sensation to feel, and how bad that sensation is.
Try using Zolstrik. It is an OTC cream, and as long as you are not allegoric to really hot peppers. It works wonders, especially in the beginning. The hot peppers trick your nerve and brain to feel something different, and it really does negate the sensations and pain.
Good luck, my fellow sufferer, this is an extremely debilitating disease!
