Sweat glands

I have a question for Norb or Allaug or anyone who knows…since I developed the peripheral neuropathy, I notice that my feet are very dry and so are my fingers. I used to have a certain amount of moisture in my finger tips, but now, quite often if I drop something, it is as much due to dry fingers as it is to lack of feeling. And my feet are certainly much dryer. Is there an interrelationship between nerve cells and the moisture in feet and hands?
