How do I know if I have CIDP?

CIDP is difficult to determine on its own. Like other kinds of neuropathy, its symptoms include loss of sensation, numbness, tingling and pain. Weakness commonly presents itself as foot drop, or other muscle weaknesses or difficulty in walking. CIDP is diagnosed through a NCV test (nerve conduction velocity). Unfortunately, many neurologists are not experts in the NCV test which is why under-diagnosis of CIDP is common.
