Hi, Bearygood
I'm probably not going to be much help
I had symptoms as a kid and dx'd at 25 without lesions. Never had another MRI until 2005 and that was just because I had some other things going on that might or might not have been MS related. I had numerous c-spine lesions and 2 brain lesions. Unfortunately, I have no idea when they actually showed up. None of them were active.
