@missbutterfly2be - Just goes to show you that the medical community really do not fully understand the complex issues surrounding PN. They can tell us what we have but not the why and to me, that's what makes this so difficult to understand. Years ago, my symptoms of PN matched those of a diabetic. Various doctors insisted on ordering blood work which showed normal levels, and my primary doctor checked levels twice a year until I told her that my wife has type 1 diabetes and on an insulin pump. We would do a blood sugar test at various times, all normal. I just switched to a new primary doctor. First question, are you sure you are not a diabetic?
