Thank you for your respond

So far we've ruled out vitamin defiency, diabetes and psyciatric disorder
What other disorders can mimic ms

Can you rule out ms as a cause for the l'hermitters sign if you can't find a lesion on the spinal cord? Or can you have a lesion, but not be able to see it?

I'm sorry for all my questions, but this really took me by suprise. My father passed away do to complications caused by ms.
