Hi countrybumpkin,
Haha, the list is endless isn't it! Oh yes, I get a twitch, always in the same place on the upper lid of my left eye. It only seems to appear when I'm really tired and the first time it appeared was the day before my wedding! Haha, given that it is really noticeable and pulls my eye obviously, I was freaking out that my wedding photos were going to display this mad twitchy woman!
The only other time I had twitches were as a side effect of Topomax which had been prescribed as a migraine prophylactic. Those were down the entire left hand side of my face. Weirdly the left side is also where I get my tingling with migraine aura.
The weird sensation you're getting may just be a slight twitch, so slight that you can feel it but not see it. x
