My whole eyeball hurt, but the middle was intensely sharp and painful. To move my eye side to side was incredible, and made me want to vomit. Felt like I had a knife stuck in my eye and each time I moved, it cut me.

My pain is always in behind the eye and it intensifies whenever I move my eyeball.

From all the replies above, it appears that like all other MS symptoms, everyone is different. If you have MS and you get eye pain, don't mess around. Go see your doctor. We only get one pair of eyes.

I couldn't resist.....It's A PITA...

This, although I could watch TV without pain, or look at the computer without pain. I had 80% vision loss in the left eye, and double vision in both (I deal with double vision as a symptom aside on a regular basis).

My pain with my O.N. attack was only when I moved my eye left to right. Then I'd get a sharp pain, though as Mariel said, nothing as severe as the other nerve pains I have either. More of an 'ouchie' after looking left or right with that eye.

Behind the scenes I had constant itchy/dry eye, found myself rubbing my eye so much (yeah I know better, couldn't help myself!), and there was otherwise a dull pain/feeling of discomfort at all times while it was flared up.
