Thank you for quick response. My wife's neurologist ordered an EMG test from a physiologist. Results said the nerves were all intact but "overactive" and should settle down. But that was 4 months ago and the condition is not much better so we continue to look. I was reading about a Nerve Conduction Velocity (NCV) test so we might want to pursue along with the ABI blood flow test that was mentioned in an earlier post.
