I have MG and my weakness is predominantly right-sided. My eye and facial droop is very one sided - although if I have really overdone it the other side will show mild weakness....but, by that time the right is so bad it only shows in pictures etc!! My arms and legs seem evenly weak but when my legs are bad I tend to limp a little compensating for the right side - so it seems I am weaker there too!

Good luck with getting to the bottom of this, limbo is not a nice place to be and I really hope you get some answers (and medication) soon. Let us know how you get on x
