@bryanbay You could consider the Mayo Clinic Care Network if any of these hospitals would be more convenient. They have relationships to consult with experts at Mayo without the patient needing to travel to Mayo. I have heard that the main Mayo Neurology department can be overwhelmed with patient requests and have long wait times for appointments.

There is also the Mayo Clinic Health System that has locations in Minnesota, western Wisconsin and northern Iowa at smaller hospitals. It may be easier to get appointments there and of course you would need to travel. Here is the website and you'll have to search for providers. There may be Mayo trained doctors working at these locations.

I can understand traveling to find the right doctor. I did that when I needed spine surgery and came to Mayo as a patient. It made a difference for me because I couldn't find a surgeon locally to take my case.

Another suggestion I could make is to look at our discussion about Myofascial Release. In some circumstances, it may help if neuropathy has a physical issues with tissue tightness so it doesn't move properly. I do a lot of this MFR work myself. It's a form of physical therapy a little bit like yoga stretching or massage.
