Hi all, longtime anxiety veteran here, now encountering a weird one!  

The last couple weeks my right thumb/index finger twitch randomly. Much less now that I stopped using the mouse with that hand, so I wondered if its RSI related, but the issue still hasn't gone away. Just happens randomly, only a few seconds each time, sometimes I can go days without it, others it happens several times in a day. 

Also, the central area of my upper lip trembles randomly too. I can manually trigger it if I move or bite it too. I can visually see it twitching in the mirror, which sucks as I hoped it would be too subtle to be seen lol.

I don't know if these symptoms happen more if I consciously think about them, but sometimes it feels like it... 

I'm waiting a while to see if they eventually go away, before caving into hypochondria and seeing the doctor about it.  

Just wondering if these are common anxiety/stress symptoms amongst you? First time for me, if so. (and as always, I hope it really is just anxiety/stress!)
