Hi guys. First time using /r/health, so I don't know if I'm allowed to ask for advice or what. Anyway, it seems that whenever I smile in a social setting, the corners of my mouth begin to twitch uncontrollably. The only remedy is immediately putting on a neutral look. Imagine how awkward it is to be laughing one minute and looking terrified the next!

I can replicate this tic on my own, but I seem to be able to control it. In social situations where I actually do happen to be smiling, however, I have absolutely no control over when it happens. It's been going on for maybe three months now, and I'm 16 years old currently. A quick google search showed next to nothing, do any of you guys know what it could be?
