I've always been one to oppose the notion that RRMS will inevitably, systematically progress to SPMS. Whether that's rational of me - or simply hopefully optimistic - I don't know for sure...

but I do know that there ARE many people who've had MS for a long time (well over 10 years) who still have the type of progression we refer to as relapsing/remitting.
I've decided I don't care what label anyone applies to my illness. I'll have to make the best of it regardless.
I'm glad you posted on this....
