Oh yes, almost every time I yawn, my face starts to twitch like crazy. Especially my eyes, but also my chin and sometimes my temples or even my cheeks. Actually, I can induce twitches almost anywhere on my body. Every night when I put my arm under the pillow when I'm lying down on my left or right side, my arm will immediately start to twitche for a few seconds. When I walk intensively, my thighs will twitch for a while afterwards... What exactly twitches in your face when you're yawning?
