I'm 23 male. Since past 1-2 months when I try to smile, my cheeks start to tremble. How does this symptom compares with stroke where your smile droops ? [1] I'm not sure if my smile droops but I'm properly able to smile, It's just that my cheeks and my smile trembles(goes up and down). In other words my smile is not stable it just shakes when I try to smile. Can this be a sign of stroke or just fasiculation ? Right now my smile is better than before but it occasionally trembles.I've also noticed muscle twitches in my body. My right upper eye led twitch sometimes. Sometimes my finger moves on its own for 1 second then it becomes normal. I have also noticed my leg moves its position slightly involuntary for 1-2 second then it becomes normal. Is this all BFS ?Past history: I was diagnosed with vitamin d deficiency with hyperparathyroid in october 2012, I don't know if its primary or secondary. The parathyroid has come down to normal levels now but my calcium levels still fluctuate from normal high to high so I'm on lose dose vitamin D. My magnesium has been fluctuating, the last time I checked my blood magnesium it was below normal. I was also diagnosed with OCD in November 2012, however I'm not taking any medicine for it. I've had one seizure episode when I was 10 years old. I usually work indoors on my computer.[1]
