i have had 8 emg/ncs's since 2003on my feet, legs, hands, arms andlower back. although i wouldnt do the tests for enjoyment, they are not that bad and i wouldnt hesitate to do another. as a matter of fact i am doing just that very soon as part of a voluntary study. there are some moments of discomfort but aree of very short duration in the overall test and certainly they were bareable for me. its not something i worry about before doing the test.
