My neck is really weak as well as my chest muscles...Sometimes I wonder if that's why I'm having twitching in my fingers, mainly the left ones. Whenever I'm in a seated position at a desk, I lean on my elbows because I need to support my torse...That weakness started to get really pronounced when I had a viral infection about a year ago...I remember going back to work and not being able to sit upright for too long without feeling like my chest was caving in or something, or my torso was turning to jello. I started leaning on my elbows all the time, even while eating.

I now notice that I have seemingly permanent bruises on both elbows, but mainly the left from always supporting my weight with that one...I must have some kind of nerve damage (ulnar nerve maybe?). That, along with the TMJ makes me think that MG is a real safety hazard! I think there are probably a lot of secondary conditions that might come from the compensation we have to do in supporting the weak muscle groups.
