I neurologist passed away Sep 2022 he did the EMG, nerve conduction test along with the punch biopsy for the small fiber neuropathy. . He almost had Ivig therapy approved with the insurance company. Now they will not do anything. I have been referred to Heidelberg Germany neurology clinic they lead in the studies of neuropathy. I do live in the US Dallas Tx. My family doctor used to work for the Mayo Clinic has offered to refer me. Do you get the treatments where you live or at the Mayo Clinic and how often? I took IVI G therapy as a little girl until I turned 18 and was off my parents insurance. The doctor passed away and my parents did not get my medical records. I have always had a low immune system. It can be given two ways IV or subcutaneously which way are you taking it?
