Unfortunately yes, even though you were tested a year or more ago, it could have been that the results weren't then consistent for MS. If you have all those tests repeated now, they may more clearly point to MS as the cause of at least some of the symptoms you are reporting. MRI's, for example, can change in a month or less, so certainly MRI's taken now may well look quite different than MRI's taken a year ago.
People often think that "relapsing-remitting MS" means there are periods of time when people diagnosed with MS have no or few symptoms, that they "feel normal". That has never been my experience. I've always had some residual stuff -- weakness in my legs, numbness, tingling, other symtoms, even when I've been in "remission".
So you talk about feeling poorly..that is pretty typical in my experience. I'm sorry.
