As you may know, none of us here is a medical professional, but we all have experience with diabetes. BL is right that those symptoms are consistent with diabetic neuropathy. From your msg, it seems as tho' your hubby hasn't been dx'd with diabetes and doesn't have any classic symptoms, and so if it is neuropathy there may be other causes for it.
Here's NIH information about neuropathy from National Institutes of Health, a reputable source of information on this subject.
