My 20 y.o. daughter is 18 mos. post TBI. About a year ago she developed a muscle twitch (looks like pulsing) in her throat; over time the twitch has involved her chin, lips, and now, occasionally, the left or right side of nose. The twitch is less noticable when she's sleeping or very mellow. Neurologist states it's from her brain stem injury - many med changes were made, none worked. There is no seizure activity in her EEG. Any thoughts? Thank you.
