lrobinson - I would suggest your husband does apply at Mayo. I am not a diabetic; I do not drink alcohol and I have no pain in feet, legs or hands. Yet, I have sensory motor peripheral neuropathy (idiopathic) with severe numbness and like Ray, poor balance. I was successful in securing an appointment in early 2020. Be prepared to submit any and all information on tests that has been performed. In my opinion, you won't find a better place. I wish you and your husband success in getting to the bottom of his problem. Ed
