I've had several NCS performed over the last 3 years. Symptoms have been tingling, pain, involuntary movement in feet/hands and sometimes face. I've had positive NCS test results multiple times that indicated a progressing peripheral neuropathy. Last week I went to a very well known university. They repeated the NCS and said that it was completely normal (just had one locally about 2 months ago that indicated the progressing neuropathy).

Anyone with similar experiences with positive/negative NCS results? Should I assume either is correct or do you do another one to try to find out?

Any ideas? What should I do??????
