If its a test called an emg dont let them do it after I had mine I wanted to kill the doctor and myself I felt like I had just paid a doctor 800.00 dollars to torture me and all I could think of for months afterwards was why didnt I make him stop It was the most painful thing I have ever gone thru but to me the worse part was that I didnt get up and leave I just laid there and let this doctor torture me for 2 hours and then paid him for it.
