I am so, so sorry for what you went through in the ER. It is incredibly horrible how you were treated, especially when you are suffering so bad!! I don't understand how supposed medical professionals can be so arrogant and jaded. I think they must just get burnt out and don't listen anymore and don't care. I really hope you go to your regular doctor or neuro (whoever listens best) and tell them about these tests and what was said (blood in urine, etc). All the things you said can be very serious and need to be dealt with. Maybe something else is going on that effects your potassium, causes blood in the urine and is possibly making the MG worse! Please don't let their ignorant indifference in the ER stop you from pursuing this until you get the answers.

I hope you have a better week ahead,
