In my opinion this vibration have to be related to some deficiency of GABA in the brain, i have read the L-Theanine helps but i haven't try it yet.
I get the same vibrations in face, head, some times my legs, and some times light headed, the only thing that helps my feel better is camomile tea or other tea that calms the nerves and mind.
did you ever figure this out.
Hi. Long before a core of findings revealed the source of my primary health issues, I also had very similar symptoms. My neurologist reached the same conclusions about me and prescribed Lexapro, which made me very sick (I stopped three days later).
I described my vibration issue as "microscopic/tissue-level" vibration in my face, lips, and scalp, as if my face tissue was being shaken in the manner that a paint can "shaker" mixes paint (extremely fast oscillation, yet in a small/confined area). As the shaking grew faster, over a 3 - 5 minute period, I would grow very sleepy, then fall asleep for usually between 12 and 20 minutes. My symptoms never included any pain.
Findings in my case, so far, include a syrinx (at shoulder-level), pituitary function @ 10% of normal, low-cortisol (40% of normal), CPK at 3x normal, vitamin D at 25% of normal, low thyroid function, low platelets, and testosterone at 60% of normal.
Good luck with your issues and your research. I will check back here periodically.
