dmarie,
I think that since you have had two doctors basically tell you the same thing...that this symptom/side effect is expected and benign...that you can safely put this worry to rest.
I have muscle twitching as a result of anxiety. I don't take meds, so it is simply a symptom for me. The less I focus on it, the better and less frequent/bothersome it is.
Here is a excerpt from a site in our Resources...a very comprehensive list of anxiety symptoms:
Muscles that vibrate,
jitter, tremor, or shake when used (click link)
Muscle twitching
So, this could be either an anxiety symptom or a s/e, but surely nothing to worry about or seek further testing for. Try some progressive muscle relaxation exercises....also found in our Resources.:)
