To update, I saw my neuro today. She is putting me forward for an EMG of my tongue next week. She said it might just be my nerves causing the twitching in there. When I try and totally relax, my tongue does calm down a lot, and there is no noticable atrophy in there, and no real weakness and I'm not drooling and my speech is okay. That should settle it. She says my strength is fine and my air way in my throat is clear, but my relflexes are brisk. I'm glad that she is taking me seriously. She told me to try and relax and not to worry, chances are, I'm fine.
Thanks for your help Al. I'll keep you all updated!
