I twitch. My eyes twitch (left more than right, but left was the one most effected by the MG) My back twitches. My arms twitch and my legs twitch

When I was at my leanest and going through rehab I could watch the muscle "jump" on my leg. My physio was quite fascinated because he normally works with people on the heavier end of the scale than I was, he doesn't normally get to see the muscles on someone looking almost like the diagrams in books.

I asked Dr. Nicole at the University of Western Ontario about it when I was out for a consult visit with him earlier this year. He said it is basically normal and it happens to everybody. We're more aware of it because we're concerned about problems and listening to our bodies more closely than most people.

That isn't to say you shouldn't look into it and be sure it isn't a symptom of something else for you... but don't be disappointed to find out that it is completely normal
