Paul, thanks for your response and I'm sorry you're having to deal with this on top of all your other ailments. I do realize that PN can come from various sources. In addition to lots of B12 and some limited B6 I'm also taking L Carnitine and Alpha Lipoic Acid. Figure those can't hurt.

I'll let you know what the endocrine guy says after I get the blood results.
