Well, I saw the neurologist today.
Despite comments from a friend that he wasn't at all any good, I actually found him rather helpful.
A thorough neurological examination, (even if I had to strip down to my underpants!).
Outcome. He isn't committing to it being Functional Neurological Disorder, or Multiple Sclerosis, until further tests have been done.
More bloods taken (7 vials worth!). Not entirely sure what he was testing for, but the results should be with my GP at the end of the week.
I'm also getting referred for a lumbar puncture
, as well as a spinal MRI *with* contrast as apparently part of my spine wasn't scanned on my previous MRIs.
So while no diagnosis yet, at least I'm getting more tests to rule things out.
