I've got it. It's not faintness (I don't feel like I'm going to pass out), but like how you feel after you've been spinning around. I assume this is Benign Paroxysmal Positional Vertigo, caused by little crystals swimming around in my inner ear, and fixed by doing some exercises I've been avoiding. But I though I'd better check with you guys in case there's something else I should be aware of. The world spins when I move my head.

Vertigo, even the "benign" kind, and MG are a really bad combination. Vertigo throws you off balance, and muscle weakness means you can't catch yourself as well. I just fell, harder than my usual graceful slow collapse.

Thanks.
