I expect in time you'll receive lots of replies. Peripheral neuropathy can be such a crazymaking condition to properly diagnose. For one thing, there are so many varieties, with each variety bringing its own symptom or symptoms. I was diagnosed in August 2022 and informed I have "idiopathic (cause = unknown) sensory-motor (feeling, balance, and gait) peripheral neuropathy." Like your husband and many here, I'm unsteady on my feet and have a wobbly way of walking, but again like your husband, I have no pain (for which I consider myself most fortunate). I applaud your idea of getting a second opinion from Mayo. I, too, have checked and double-checked my own diagnoses. Have you and your husband already requested that second opinion? One way or the other, it should prove to be a great relief to both of you to see if two diagnoses dovetail and for your husband to have a surer idea of what is causing his difficulties. My best wishes to you both! –Ray (@ray666)
