Thank yall so much for your replies, i really appreciate it!

Geod- Funny you mention Isaacs, I have it on my list for tomorrow (my university neurmuscular specialist appointment) to ask about getting tested for.. From what I understand it can affect your tongue as well. Thanks so much for the info, that is really interesting that there is a relationship between that and MG too!

Kage12- Thanks! That's interesting that they repeated the test and it was positive the second time around.. I guess the Musk labs aren't in the typical MG panel- my labs were run by Quest, not sure how much confidence I have in them, I have had a few bad experiences. When you say they diagnosed you from your physical and story too, how dramatic is the weakness with effort and then how dramatic is the improvement with rest.. do you feel totally normal after resting for a few minutes, or do you always feel kind of weak and then its just worsened by activity and never goes away completely?
Thanks again so much for yalls time! I'll update yall after my appointment tomorrow, i'm SOOOO nervous!
