I am currently in diagnostic limbo, going to the university specialists this week. Anyhow, I was curious if anyone with MG here has focal muscle weakness? I have periods of time where I can't hardly smile and if i smile or laugh, my face simply won't have the ability to smile, laugh or make the "crying" face for a while afterwards.. the muscles almost tremble with exhaustion for a while.. same goes with the rest of my body.. however I also have constant weakness in my tips of all fingers and entire thumbs.. it's been constant for almost 3 months now.. I have a triple furrowed tonge, slurred speech and swallowing feels difficult- all at the end of the day or after talking a lot. My initial MG serum panel came back negative- though that didn't include MusK (plus I have never mounted antibodies in my blood my entire life- found this out for vaccination purposes). Anyhow, any insight/experiences would be greatly appreciated!
