Hi well at least that is done. I have had 2 of these emg/nc not so fun.I had the ssep too which for me was done when my other tests showed limited and they were still concerned. My ankle often feels like it is broken too. I have the major rsd pain but also PN in my inner ankle/foot/calf. I think the emg is to rule out other things and to see severity of damage but also to be able to follow up to see if repairing or more damage is happening but I could be wrong. I felt the same way as you though when I had a few of these done and then the treatment was the same before the test and after and I went through that but I guess it is better to rule out other things. Make sure you keep copies of these too for your records and to show other doctors you see. Hope you feel better and you are recovering
