Hi Celia @celia16, Thank you for the private message. I hope you don't mind but I thought I would respond to your private message question in this discussion so that others with your symptoms and type 1 diabetes may also be able to share their experience with you. To answer your first question, I am doing fairly well with my neuropathy as it has not progressed and I have some feeling returned to my feet. I posted my neuropathy journey story in another discussion here - https://connect.mayoclinic.org/comment/310341/.

You mentioned you have type I diabetes and a little numbness in your feet and you have good sensation and circulation. Your neurologist says it’s not neuropathy and you were asking how my neuropathy was diagnosed. My Mayo neurologist scheduled some lab tests including an MRI, nerve conduction test and a physical exam and diagnosed me with idiopathic small fiber peripheral neuropathy which he thought was probably genetic. From what I've read the gold standard for diagnosing neuropathy is a skin punch biopsy which I didn't have for the diagnosis. This short video by Matthew B Jensen Assistant Professor of Neurology, University of Wisconsin that gives a good explanation of how the different neuropathies are diagnosed.

Another key to my puzzle could have a connection to your symptoms. Until recently I have always been labeled pre-diabetic due to not having my blood sugar under control and also being quite a bit overweight. I started working on that a couple of years ago and have been able to improve my numbers and weight issue quite a bit through intermittent fasting and lowering the amount of carbs I eat. There is another discussion on that you might find helpful here:

I'm glad to hear that you don't have any pain with your neuropathy symptoms.
