Thanks, Twitchy and Illinijohn for that information. I have a neurology appt. scheduled for Jan. 8. I hate to wait that long, but I'll just have to be patient. And I'm researching information on Restless Leg Syndrome. I also ought to mention that I've been taking Pravastatin (for cholesterol) for 15 years now. And I began taking Lisinopril (for high blood pressure) a little over a year ago. So I wonder if one of these could be causing the muscle twitching.

When you go online, there are so many causes of muscle-twitching that it's mind-boggling. Some very serious, others mild and benign. Right now I just have to bear with it.
