My first experience with Optic Neuritis (5 months after my hip and thigh went numb) was my first real clue that I had MS. (had a doctor blow me off on the numb thigh)

When I had ON, I had a weird problem with my eyelid, it seemed like it didnt want to close all the way. Not only did my eye hurt like crazy, and I had the big blind spot, but when I closed my eye, I could still see thru a little crack where the eyelid didnt close all the way.

That was a pain, my eye felt dry all the time and I had to use eyedrops occasionally.

Right now my biggest visual problem from the MS is the stupid eyelid twitching....that drives me bananas!
