I have intestinal issues as well. MGers often have more than 1 auto-immune disease. I think my intestinal issues are another auto-immune disease because they subsided after a few weeks on anti-inflamatory meds.
I would follow up on the intestinal issues, it sounds like the pain I used to get with gallbladder.
But I also get a similar discomfort with MG in my side which I think is weak intercostal muscles. I also get discomfort in my chest due to weak pectoral muscles.
From what I read the SFEMG is the definitive test for MG when antibodies are negative. Someone in another post mentioned a QMG, which I never heard of. It looks like an assessment tool for MG. Here is a link:

Good luck with your appointment,
