When my MS started getting to the point of no full remissions, I figured I had slipped into SPMS.
If your symptoms are new, intense and last, then you are having an attack/flare/exacerbation. If your symptoms are not new or intense and they don't last, then you are probably have a pseudo flare, brought on by the weather, added stress, a flu bug...etc.
