Thanks Kendra, and everyone else. My doctor did call the mg specialist, and he got my appointment moved up. A week. I still have almost three weeks to wait. But I'm definitely going to wait it out, because my symptoms are getting clearer and clearer. By the time I get to the new doctor, I bet he gets some ideas just by watching me lurch into his office! My muscle weakeness seems to be settling into my hips and shoulders. From what I've read, this suggests either LEMS or limb-girdle muscular dystrophy. I'm pretty convinced that the Mestinon helps, so my money's on LEMS. Today, anyhoo.
