As cliche as this may sound but I think I might have turrets? I'd heard the term though didn't know what it referred to, I would just call what happened my "spasms", it didn't occur to me that it could be turrets till I had heard of someone that had an extreme case of it and some of the symptoms sounded an awful lot like what I had experienced. They've been happening to me since either 8th grade or freshmen year in high school, I am now 20 going to be 21 this July, and it's gotten worse over the last couple of years. Most symptoms are I suddenly twist my head to one side or the other, say damn suddenly, suddenly start whistling "Amazing Grace" for no reason, shoulder spasms, and suddenly recite this poem that I made up for no reason. Sometimes it'll be triggered by thoughts of previous events where I felt either ashamed, embarrassed, or stressed. Typically these symptoms will occur while driving or when I'm by myself, they sometimes occur in public, though not often, and when people notice I'll say that I had a pinched nerve or that I felt a bug bite or something to avoid embarrassment. I find that if I can find an activity to focus my mind on that it tends to keep spasms from occurring.
