I’ve just looked back at your last thread and it sounded at that point that you were struggling with your current neurologist.
So actually, a different neuro might be exactly what you need.
It’s possible that your current neuro is uncertain because you have tested negative for Oligoclonal bands. And I don’t think you can test negative for O bands then have another LP with a positive result. But it’s possible that new methods o testing the CSF could throw up differing results. (I don’t know this, I’m just hypothesising.)
And maybe the current neurologist has someone specific in mind to refer you to. Perhaps an MS or an ADEM specialist? Or someone who is more experienced with complex diagnoses?
I’ve seen any number of neurologists over my 20ish years with MS, but not for initial diagnosis. But then my diagnosis was more straightforward: initially told it wasn’t MS (although that wasn’t exactly true), and then following more relapses, that it definitely was - using precisely the same evidence as the initial negative message. (The ‘risk sharing scheme’ had just been introduced so a diagnosis was more valuable - finally DMDs were available!)
So where do you go from here? Is your current neurologist referring you to another? Or do you have to go back to your GP for a new referral?
Whichever it is, I can only think that it would benefit you to see someone different.
