My grandmother had MG my mom definitely has the bent neck, swallowing issues and no voice for years! I now ans seeing more and more symptoms coming out at 54. I have a tendency to …just fall, issues with walking. My partner says I’m dragging my leg! The feel heavy and so do my extremities. I have had the cross eyes but didn’t even think it had anything to do with MG. I don’t have the droopy eyes by they feel heavy often. Also, I was diagnosed with systemic lupus.
