Hi Rick, I have been having the EXACT same question! We recently saw the neurologist for our just turned 7 year old sons tics. He has eye blinking grunting humming neck stretching plus a few others. These all started all of a sudden. He has had an arm raising thing he's done for about two years but we never thought of it as a tic, more of his way of showing excitement and controlled vs spontaneous. When I showed a video of this to the dr combined with eye blinking he said it looked like a complex tic. Everything I read, like you, said nothing about this with being transient. The dr said it still could be and gave an example of his own son having a complex tic. I still question it and think we may be faced with TS though. One thing I read about TS vs transient was that TS will typically have a spreading of tics, for example eye blinking to neck stretching. I am just devastated and overwhelmed with the "watch and wait" period we are in now. I am brand new to this forum, so maybe some of the veteran members can weigh in here.
