Try to focus on research instead of worry. I like to channel my worry to learning and healing. Finding an integrative MD is good too. They usually know a lot more about healing vs just giving meds like reg. docs. They are MD's so they can give meds, but they are usually very interested in healing and finding the cause.

There are many things you can do. There is also hyperbaric chambers that are used for neuropathy to bring microcirculation to the tiniest of nerves and vessels.

Always keep learning.
