I was "twitcher" for a few years. It IS annoying!

There were times it would be twitching and not visible but you could feel it under the skin like an electrical current. Mine was always on the right side of my face, but they could pop up anywhere, one muscle fiber just twitching away, almost looked like something alien was trying to get out when it was my leg or abdominal area.

I used to put fingertip pressure on the twitch, usually on my eyelid, my undereye area, my cheek or my upper or lower lip. Sometimes it worked, sometimes it didn't.

Applying ice to the area for a few minutes worked for me too, when it was particularly bad. Occasionally the facial twitching would spasm and make my face twist up on that side, which was kind of funny when you looked at it clinically (I called it the 'Elvis look'), but annoying as all get out. I would use an ice pack for a few minutes and it would calm down. It's said to fool the nerve or something.

Doc said heat and stress make it worse, and called it 'fasciculations'...realllllly?

I haven't twitched in a few years and I don't miss it at ALL!
Hope this helps, I truly feel for you on this one!
