Momma, so sorry you had a trip to ER, I myself don't go anymore {I know thats wrong} but I get tired of them looking at me like I'm crazy, last time I went they couldn't even get my blood gases and then they transfered me via ambulance to another hosp where I spent 3 days {turned out I was allergic to inhalers I was on} my blood work all came back showing MG but since I can't take meds they released me. They wouldn't do plasma exchange because they said they lost 3 MG patients doing it in just that month. So I live quitely, when weakness starts, I stop, thats all I can do.
