It started sometime yesterday in my left upper lip. We’ll call it my sneer muscle. It’s firing of its own accord, an involuntary twitch that pulls on my lip and my nose. To look at me, I don’t think you’d see it when it happens.
What’s going on here? Is it stress? Caffeine? Nicotine (from vaping)? Testosterone levels? Pinched nerve? Google it. Oh God, whatever you do, don’t Google it.
Like I said: nobody’s going to notice it.
