I Had An Electrophyisiology Study And Cardiac Ablation About Two

I had an electrophyisiology study and cardiac ablation about two weeks ago. i went back to the dr yesterday for an ekg. They called today and said she seen something on the ekg that she wants to talk to me about. I also informed her that i was having pain in my neck that feels like a cramp. The ablation was unsuccessful and i had to start taking flecinide. Any thoughts on what others issues could be causing the feeling in my neck?
