It's temporary which is good, but it was definitely very scary at first. My left side was affected last year 👎🏼 same as @tayek I couldn't move my left side but I could blink, just not all the way. It made me extremely self-conscious :( it took me about 4 months to recover
It's a very unsettling feeling...especially the last flare I had. My right side was affected, and I couldn't move that side of my face or even blink my eye.
