Sometimes we can be the most help if all symptoms are listed, maybe the most bothersome to the least..

I don't know if she has described all /most of those to you?

Are her hands the main problem, and then her feet , are they presenting symptoms in a similar way?

Did the neuro say the names of the 2 affected nerves?
Has any MRI/x ray of her c spine been done to rule in/out issues there?

Any other injuries or conditions to consider - now or in the past?

Could it be possible for the hand problems could be some sort of repetitive strain injury? Any neck or shoulder pain or stiffness?

There are so many things it could be from, that those web searches don't even consider, they really only come up with the more well known by name conditions.

Sorry I asked so many questions , but it helps to pin things down a bit more for us.
