How does the diagnosis process work from here?
I'm M 45 in the UK.
My GP originally sent me for an MRI of my spine because of ongoing back issues; we all assumed it was a trapped nerve or a bulging disc. However, after the consultant radiologist reviewed the scans, I was referred to a Neurologist due to "areas of concern."
At my NHS neurology appointment, the consultant sat me down, went through the MRI, and—BAM!—just like that, told me, "We strongly suspect you have Multiple Sclerosis."
I was in total disbelief. I only went in there for a bad back. When I questioned the scan, he explained that he and other senior specialists had reviewed my MRI, symptoms (various things like coordination, numbness, pins & needles, pains, cramps & peeing problems etc) and timeline, and they were almost certain. He ordered a brain MRI and a lumbar puncture (LP) immediately. Within a week, both were done. After the brain MRI, he called me to say that, as suspected, there are lesions in my brain as well.
A couple of weeks have passed, and he called again to say the LP results were actually inconclusive. He’s now discussing my case with his colleagues in the NHS Trust (an MDT meeting) and wants me to come in for a review.
I have that appointment in a few days and I'm spiraling a bit.
Is this where I’ll get a formal diagnosis?
Will he tell me what "stage" or type I have (e.g., Relapsing Remitting)? From my own reading, I suspect I might be Primary Progressive.
Will he suggest treatment options right away?
Will I be assigned an MS nurse at this stage?
Has anyone else had an inconclusive LP but a confirmed diagnosis based on scans?
Any advice for this upcoming meeting would be appreciated.

I would encourage you to take vitamin D3 and B12 daily. Both have proven benefits for MS. Even if you aren’t sure it is ms it won’t hurt. Usually they will talk to you about DMT options. There are six high efficacy treatments. I am on Ocrevus infusions. I was recommended the Mediterranean diet. Excercise helps a lot as well. Not sure if the process is different in the uk
You get diagnosed when the MS specialist team review the scans and other tests to confirm diagnosis. My neurologist referred my to the main hospital that manages MS patients to be officially diagnosed. I actually got assigned an MS nurse whilst I was waiting for diagnosis. Medication was decided with the doctor at the hospital when they confirmed diagnosis and we talked through options. I did not push for a highly effective DMT. If I had my time again I would have as now on Kesimpta and it's been good
