B12 & posterior cord syndrome

[WPTC]

Hi, sorry to bother you all butI'd be so grateful for any advice....does anyone think I might have B12 problems?

I have been veggie for 30 years, not vegan.

I have a long history of reducing sensation in that started in my feet 13 years ago & has worked it's way slowly bilaterally symmetrically in places up my legs & parts of my "under -carriage"

Not much tingling.

Repeated visits to my GP over the years eliminated Type 2 diabetes & various other possible causes the possible causes such as arthritis of the spine, & all my blood tests, except vit D, were in normal range so GP did nothing except put me on vit D & said try NSAIDs to see if any improvement....but no difference.

Eventually got referred for nerve conduction tests for peripheral neuropathy, which showed peripheral nerves were normal. That was just before covid hit.

After the pandemic I eventually got to see a neurologist. 6 months later got MRI scan which showed posterior cord affected from C5 to C7 was causing sensory issues .

6 months later they did tests for functional B12 which also were in normal range. 2 years on , & no follow up so I don't know if it's PA or not, or if I need B12 injections or supplements?

I'm worried in case it's subacute combined degeneration & what might happen in the next few years if it continues, & the medics can't find what is causing it.

Any advice or thoughts would be great.

Thanks so much.
