it sounds like you had a hard day.
lesions on the optic nerve can be very difficult to spot, even if the eye surgeon is looking directly into the back of your eyeball, with a bright light peeking only see the very tip and of the optic nerve, the nerve itself is about 2 inches long which makes it very difficult to see. I know when my eyes surgeon does my checkups he makes sure to caution me that he can only see the tip. An MRI can locate the nerve and lesions on the nerve, but they have to be looking for that, and normally they want to use GAD intravenous dye. Were they looking for that when they did your MRI? Visual issues scare me more than any other.
Since there are so many other diseases that can mimic MS, it's very difficult to make a quick diagnosis, sometimes the waiting game is more frustrating than the disease itself. You are in good company here, most of us know just how frustrating that kind of day can be
I hope you're feeling better today.
