I would start by looking through this
I don’t think anyone understands their MRI!
The consultant probably more interested in your history of symptoms and their physical examination.
A bit confusing trying to sort out the chronology and where you live. Never heard of a physio arranging an MRI. I see you are expecting to see the Neurologist again. Good luck with trying to understand the MRI, but it is not a simple mapping from damage to symptoms. Also in the UK if you are diagnosed with MS you would expect to be allocated to an MS Nurse or team.
I think a lot of us get obsessed by our MRI but I have never actually seen mine or discussed it with my consultant. My initial reading showed that my symptoms could be related to both damage in my brain and my spine. Then I just started to work on how exercise might improve my symptoms. Gaining a better understanding of the MRI wouldn’t have helped!
