I googled conduction block : conduction block a blockage in a nerve that prevents impulses from being conducted across a given segment although the nerve beyond is viable.

Given that I had zero response is it safe to say that what I have then is a conduction block?

Which then means that I have CIDP, which the makes sense why they are testing me the way they are.

(spinal tap, EMG #4, And possibly nerve biposy)

Well, I guess I should count my blessings.
There are treatment options for CIDP.
