Coolsculpting on arms, now I'm having tingling that is spreading and having trouble using left hand.

I feel like the applicator on my left arm hit a nerve so it was not placed correctly. I am having trouble using my left hand to pick up objects or drive etc. I have had Constant tingling that is now spreading down into legs and feet. I also have some burning feeling that comes and goes and am still numb. I went to doctorand he gave nerve pain med. I am 1 week out. Is any of this cause for concern?
