Hello Chris @artscaping Thank you so much for your reply. I read your response to my dad, and here are some of his responses.
He started noticing the plastic feeling, approximately 3-4 years ago, which was his first indication of neuropathy. He said all he knows, is that it is peripheral neuropathy, according to a neurologist at Minneapolis Clinic. My dad hasn’t tried any medications yet, but is hoping for suggestions, as the numbness seems to be increasing. He does not have any pain, with the numbness. He is still mobile, and has not yet needed a walker or wheelchair. My dad has gone to Mayo Clinic, for other health issues, but not yet for neuropathy. He is thinking of making an appointment in Mayo’s Neurology department. We just appreciate any suggestions on things that have helped others. Thank you again, for your warm welcome.
