wiggly elbow muscle

Is this / could this, be a symptom of MS or is something else going on?

My right elbow muscle, right near the inside bend is moving on it’s own. Like when you get a twicthing eye? but this is my arm bend and it wont stop!!!

It’s visible too and looks like something is trying to jiggle it’s way out … plus when it does pause it’s only for about an hour and it hurts like toothache during this time.
