Well, I can relate. My tongue tingles, buzzes and quivers sometimes when I look at it. Sometimes it feels contracted, then when I look at it there is a dimple in the middle. Sometimes my upper lip will quiver when I look at my tongue. This has been going on for about 6 weeks, and has been an extreme source of anxiety for me, because of the googling thing I did. I've been told by 2 neuros it is anxiety because I have no clinical tongue weakness. I would be curious to know how many others have experienced this.
