I agree with others. I wish I had answers for you.
The internet can be a wealth of info for health advice, keeping in mind that the advice may not be entirely correct but always worth investigating and then asking your physician.
You’ve made a wise decision to network and ask others. The first time doing this can be awkward. But you will get answers and advice that may lead you and your husband to other sources of good info. You might want to search and join forums that discuss the various types of neuropathy.

When faced with problems go outward instead of inward. Ask others and investigate. There are always others that have similar problems who can offer support or advice.
Good advice. I wanted to come here first. Everyone has been so helpful, and have offered some interesting theories I hadn't thought of.
