-- it would be very unusual for a doctor to recommend, or try to get, IvIg treatment for a patient unless there is definite evidence of autoimmunity, as the treatment is an immune modulator.

This implies that some sort of serological and/or other testing has been done to document autoimmune markers.

There have been numerous people who have used IvIg treatment with varying degrees of success, and not just for neuropathy (and many have posted here and at other Neurotalk boards), but they generally have fairly well documented autoimmunities.

Do you have copies of your test results? (Everyone should.)

Do any of the tests on the Liza Jane spreadsheets look familiar? See:

(These were devised to be a very comprehensive list of tests for neurologic symptoms--and a good way to track/results patterns over time.)
