Hello, Billy. It's nice to have you here.

Yeah, I get twitches and I believe that it's a side effect of Seroquel, which is an anti-psychotic drug that I take. I never had twitches prior to Seroquel, but it happens me to now; typically I get them right after I take the medication. My arms and my shoulders twitch the most.

So, to make a long story short, I don't know if anxiety can cause twitching, but I know that medication can and, in some cases, does.
