Hi ladyinpain,
Yes, when I'm overstressed or really, really anxious or really tired, I occasionally get a bit of a twitch around my eye that's called a fasciculation which is an involuntary muscle twitch.

I've had them in my upper arm muscles near the shoulder as well. They feel a bit like a flutter and they don't usually last long. My understanding is that they're not uncommon.

I take a few supplements, not many. One that I do find helpful for these is magnesium.

Here is an old thread I started in the Vitamins Forum asking for help when I was in a really bad way during months of severe weather events in my area.

There may be some helpful info. in there for you, ladyinpain.
