Hi and thank you for your question! We might injection Dysport (or Botox) to neck for a number of reasons - platismal/neck band, migraine or muscle spasm treatment. In your case, you seem to be experiencing some signs of over-reaction to Dysport although as the treatment results settle in, you might see some improvements. Nonetheless, I recommend that you do a follow up with your injector for an evaluation. I hope it helps and good luck!
