So sorry you're having "MS problems" now.

This disease is really the pitts!!!

Yes, I have trouble with certain lights also. The flickering is horrible and I feel the same as when I used to get motion sickness. Yuck! Do you notice the same thing happening when you're in a vehicle and the trees or telephone poles are passing quickly through your peripheral vision? I haven't been traveling in a long time, but I do remember that sickening sensation.
Being in a flare, it's probably more exaggerated and noticeable too. A flare used to always affect my balance which made me nauseous. Now, being spms, just going outside into the sunlight without sunglasses sends the sharp pains shooting through my eyes and head.
Isn't life wonderful!?!? Seriously, hope you feel better soon!!
