Hemifacial spasm, with no other stroke symptoms. High anxiety 27F

I’m 27F, 115 lbs. I’m on hydroxyzine 10 mg, which I take as needed (usually every other night to help me sleep). I occasionally use low-dose THC—just a couple of hits at a time.

Today I was about 20 minutes into yoga, and during mountain pose I noticed twitching and numbness starting on the right side of my face. The sensation didn’t go away, so I was able to grab my phone and record it (video linked below).

I’ve had similar episodes before, usually triggered by stress, but this one lasted longer.

Some background: • Chronic joint and body pain, no diagnosis, inflammatory markers all negative. • History of domestic abuse involving asphyxiation and a head injury that was never evaluated or treated.
