Face after masseter Botox was super snatched, but 3 months later I now have turkey neck? (Photos)

I got masster Botox maybe start of July? Loved the results my face was super leaned out, not that it never wasn't before, but only recently a few weeks ago maybe my face has become super bloated and got a lot of excess fat. This is not weight gain I live an active life style of running and healthy eating and only a few weeks ago before this happened my face was fine. ( second photos) was this caused by the Botox or something else?
