Hi, I agree with j_sageurge.I hope that you are aware of the asymmetry of our body, this includes the tongue. As a tongue twitcher myself I know how you feel – been there (still am). You have no idea how many times I thought I had atrophy on my tongue! In addition, when I stick my tongue out it tends a little to the left (where I first started to twitch). I showed my neuro that, but he wasn't even slightly concerned. BFS was his bottom line. I try not to test it anymore since it can drive me totally insane!! I suggest you do the same.May
