Often I feel it is less the hospital name and more the doctor you get. My best doctor was in my home town MI. I had a called a major teaching hospital which was suggested here. I explained my history a little and what I was looking for and they matched me with a doctor who I felt was way better then any I saw at Cleveland Clinic or UCLA for example. It is important regardless to get a doctor who deals with the specific condition you are facing. Otherwise mistakes happen.
To the OP do you have a major teaching hospital in your area?
Stagger though one may always have PN I do feel with proper treatment it can get better whether that mean from meds,treating the underlying condition,other treatments. It just takes time unfortunatly.
