Just an update, I woke up this morning and most of the pain in my eye is gone. It lasted from around 5 p.m. until around 2 a.m. I was also kind of nauseous from the pain last night, especially when I stood up or leaned over. (If it had been ON, wouldn't the pain have lasted longer?)
This morning, the vision in my left eye is very blurry. Even with my glasses on, I can't see well out of my left eye. It feels like there is a film over that eye and I keep trying to blink it away, but it's not clearing up.
I'll mention this to the MS specialist at my appointment today. Thanks again for all of your help.
