Hello Barbie @6969, welcome to Mayo Clinic Connect. Thank you for being an advocate for your daughter. It's good to learn as much as you can about a diagnosis or health condition. Connect is a great place to ask questions and learn what others with similar health conditions or symptoms are doing for treatments. Here is some information on polyneuropathy:
