One way of looking at what the doc said is this: PN is due to something else. Whether an inherited disorder, diabetes, injury, nutritional deficiency, or whatever.

Of course, you know that. Unfortunately, the differences in doctors' understanding and use of the language makes talking about it futile in many cases. You'd have to sit down with the doc and find out what his definitions are as opposed to another doc, a reference material, etc.

Ack!
