Yes all the time 24/7. They are called benign fasciculation Syndrome. It's common in fibro. I hate it!! Mine does it continuously.

Now that I have seen this post, I have noticed more involuntary movements and twitches

I had jerking, feeling of bugs crawling on me, knives stabbing me, twitching, etc. My rheumatologist finally put me on Tomamax to give me some relief. It has made a huge difference.

I get these at times honey xx

I used to have them all the time. Many times a day...several dozen. They were worse at night. They stopped about two years ago. Don't know why they started or why they stopped. Glad they did,,,hope they don't call me back
