Linda, Please quit guessing and playing with meds and go in! What if it wasn't the thyroid med? Going off of it can actually make MG worse!!!

The symptoms you describe are disturbingly similar to an MG crisis. If it had been me, I would've gone to the ER. Why? If the probability is high that you have MG, you aren't on meds and are getting worse, you can quickly go into an MG crisis.

An MG crisis is hard to predict. Yeah, a thyroid problem can cause MG to be worse but more than likely the lack of any meds is too!

You can have MG and not have positive antibodies. Did they do the MuSK antibody test? And please get your records!

Those sudden episodes of weakness are what precipitated my MG crisis. You may get better after you rest but that is deceptive!!! I had gotten so weak so slowly that I didn't even know I couldn't squeeze the fingers of the Urgent Care doctor. Within a matter of two hours, I crashed.

It doesn't matter if it's a holiday weekend. If you get worse, either dial 911 or have someone drive you (911 is better). Any MG expert will tell you that it's better to feel stupid with MG than to be on a vent!

Twitching muscles can be a sign of MG getting worse. It can be an electrolyte imbalance too.

And please stay out of the heat. If you are doing poorly, even a minute in hot weather can make you much worse.

I hope you will call your neuro and seek out help. MG is nothing to mess with.
