With the help of Wiki a tic is a twitch or sudden movement. Focal sounds like eyes and multifocal sounds like lots of them. Many sudden and rapid twitches of the eyes??? Is that what you have?.
Focal = focus/location. Multifocal = many locations. So it's motor tics in different places in the body.
Sorry to hear that @mc9 i hope it's manageable and they can help with some coping techniques.
