Does your husband have diabetes?
I ask because Neuropathy is a very basic word-term that applies to a broad variety of observable symptoms and can be the result of a large variety of causes; but diabetes is one possible type of cause and diabetes is also a more frequent medical condition these days.
Here’s a couple links that may help.

Thanks, Wuli, for the links. No, not diabetes.
