MS is so so unpredictable, that the only thing that you can be sure of is it's unpredictability.
I had my first major exacerbation in 1974, went through early "Mini paws" starting in 1980, was in remission 'till my second excerbation from He**, in 1992 and SPMS by 1996.
I would have believed this old wives tale, back in the 80s, but not anymore. Stupid scummy disease.
Keep your hopes up, it's all we have.
