Billye, sorry you are feeling bad again... I know Dahlek and others have a number of sites - here's a couple of them....

I think most people show autoimmune markers in spinal fluid, ANA bloodwork, etc... as well as the type of damage that is shown by NCS/EMG - also onset I belive is important....
For my diagnosis - I did not show autoimmune markers but onset was immdiately after a respiratory infection - (onset after an infection or bout with a virus etc is typical), literally waking up one morning with a completely numb hand and foot, and quickly progressed from there with stumbling and falling, weakness, etc, and confirmed by NCS/EMG and sural nerve biopsy that showed demylination and degeneration, axonal and severe nerve fiber loss.....
I'm sure you'll get lots more sites tomorrow - maybe glance at the CIDP forum too?????
Hang in there
