About tics. Tics appear without Tourette's. Quite frequently too. in autism, there can be tics too, besides stims and repetitive movements.
Quote:
Immediately preceding tic onset, most individuals are aware of an urge[6] that is similar to the need to yawn, sneeze, blink, or scratch an itch. Individuals describe the need to tic as a buildup of tension[7] which they consciously choose to release, as if they "had to do it".
I had tics too, I know a lot of NTs who have/had tics because of stress, anxiety and tension.
http://en.wikipedia.org/wiki/Tic Surprisingly good basic information.
But I have no idea whether what you experience are tics or not.
