Hi there lynxgal
I havent been diagnosed with MS but I am suspicious of it. I get muscle spasms in my face all the time. When i smile the right side of my face twitches, when i close my eyes my eyelids flicker, and when squinting/straining, my eyes twitch too. again i dont get doulble vision but my vision seams jumpy.(hard to describe really). It also seams to me that when I get this strange feeling, like I can feel my pulse, my eyes seem to jump with it, vision disturbance yes, like my actual eyeballs are pulsating sounds gross feels gross but they actually arnt moving. I had my poor husband looking into my eyes for a half hour lol, he thinks im cracking up...
Hope this helps with your question thats my experience anyway...
Take care of yourself
