Unless you haven't been DX or you are in a trial that requires them, or suspect a tumor, I say never. The MRI is a good dx tool and an iffy progression tool. It doesn't always coincide with your symptoms though, so why bother?
They are expensive and very uncomfortable to most people. I've had 2 in the last 15 yrs....1 in 1993 for re-dx and 1 in 1998, because the Neuro said I hadn't had one in awhile..

.....no changes. The Doc nor I have seen the need for any more.
If you are a worrier, like me, and you would feel better, having an MRI, then you should, just to make sure.
I hope your new symptoms are just temporary, Janie, and you feel better very soon.
