I had a very bad reaction after my EMG. I had been having parasthesias in my legs and some burning pain in my feet for a month, so Dr. ordered me an EMG. Night after the EMG I woke up with parasthesias all over my body. Dr. said it couldn't have spread due to the EMG, never seen it happen before. But within days it spread all over and then I started to have burning pain too, all over body. Dr.s insist EMG didn't spread it, but I'm not so sure.
