god- that’s the million dollar question. assuming you’ve got rrms, i’ve heard some relapses can last months, so you could still be on one since january. im not sure of the ‘less than a month’ suggestion you refer to. i thought new debilitating symptoms signified relapse, but not necessarily if they’re not debilitating… i rely on what my neuro tells me, but its not always clear cut to him either.
i will possibly get shot down for this suggestion, but i believe that a relapse is when a new set of symptoms which are causing significant problems take place en masse. my last (2nd) relapse took place in March and i had visual sensitivity to light, extreme fatigue, affected speech, increased mobility and balance problems, cognition problems. i am now ‘out’ of relapse but still suffer from fatigue, intermittent affected speech, some cognition and balance problems.
hope that is of some help, and to those greater in the know, PLEASE feel free to correct me. everything is a learning curve!
