i have had quite a few emg/ncs's over the last 11 years and while i wouldnt describe it as pleasurable, for me it was never a very painful experience. i wouldnt hesitate to get another one. for me its the only test that has ever come out positive. the fact that i have large fiber axonal peripheral neuropathy with demylelination. by doing them over the years i have been able to chart the spread and the degree of my pn. it has gone from mild-moderate in my legs and feet to severe and is now moderate in my hands. there is a reason i am keeping track of this that applies in my case due to the circumstances of my exposure to toxins that wont apply to you so you wont have so many done.
reasons for doing the tests, it establishes that you have long fiber peripheral neuropathy in case you ever need to apply for disability down the road. it also is used to determine the areas affected as well as degree of damage and wether it is primarily axonal damage or damage to the myelin sheath. this will help to narrow down possible causes and suggest other possible testing that needs to be done. the tests can also determine wether your problems are being caused by your back or nerve impingement from the spine.

the needles being referred to for the emg portion are very thin needles and most likely wont be even felt in most of the tested places on your body.
