You don't have MS, or anythign else like that. I had the same problems with my eyelids and cheeks and everywhere else. I even had the biggest one I've ever had a few weeks ago. One morning, a huge muscle in my back/shoulder blade was moving my entire right arm as I sat at my desk. It had to be visible to others. My eyelids went crazy for about two weeks. My general rule is that when a new one comes on, make note of when it starts and then if it is still there two weeks later, pay more attention to it. Generally, mine are gone in a few days. Dude, I had the same fear. First it was ALS...then MS...now it is Parkinsons. I am 9 months into this crap and am getting a lot better at it. I rarely notice it anymore and the fact that everyone references anxiety is the God's honest truth. Anxiety exacerbates everything. If you had MS, your eyelid would not be the problem...you would not be able to move a leg (or something major like that). If you really need to, get an MRI, but I will tell you, I sais the exact same thing to my neurologist. I whined about it and said, "I'm scared I have MS!!!". He finally said, FINE! lets get your head scanned and sure enough there was nothing to be worrried about.
