I recently got back from a stressful 3 day trip where I probably didn't eat enough food because I was very anxious. I believe I already lack few nutrients because I'm a vegetarian of 4 years and that might be why I'm experiencing this. On the second night, I noticed that when I blinked, my nose twitches. It's not really a twitch because I can't feel it happening, but if I press my finger on my nose I can feel it move. I took a video of it and it looks like a dimple almost. It only happens when I close both eyes. Throughout the day I also had twitching that I could feel on my forehead, right jawline, arms, knees, and feet. What could this be, and how can I potentially stop?
