Please read all the info carefully. I don't know what other drugs you are on or if you have high blood pressure but you really have to read about drugs before you take them.
Be careful with the steroids. I'm sure you know that it could make your MG worse right away.
That was good info, Geode.
Seamus, Go see a rheumatologist! They'll take care of you right away.
WW, I hope you'll get the relief you need to keep on working. There are alternative medications, which you might want to ask a rheumy about. And if you haven't thought of it, adding flax or fish oil or other good omegas into your diet (like walnuts), that would help somewhat.
