Last one for tonight - then I really must go to bed.
So presumably you’d had at least one earlier episode, which led MS to be suspected, then you had one which enabled it to be confirmed?
If your neuro hasn’t already discussed DMDs with you, it’s probably because either your episodes (relapses) haven’t been frequent enough (not two in two years), OR, possibly, because he doesn’t deem them severe enough. The criteria do talk about “clinically significant relapses”, rather than just “relapses”, so I’m not sure how bad one has to be, before it’s deemed “clinically significant”. Almost certainly anything disabling would be, but if it was minor sensory stuff, that didn’t last very long, I guess that might not be considered “significant”.
Either way, it’s really your neuro you should be talking to, about whether you fulfil the criteria. Because it hasn’t been mentioned yet (at least, I don’t think so?), I’m guessing the answer is “No”. But to put your mind at rest it hasn’t just been overlooked, I think you should ask the question.
Do make sure he’s aware of any earlier episodes you now think could have been relapses, and try to recall dates, if possible (at least roughly).
I was asked to put together quite a detailed timeline of everything that had happened, and I included stuff I wasn’t quite sure about, too. So I had things like: “Hurt leg??” and “Mystery bug??” - all stuff that looked, with hindsight, as if it might have been a relapse.
