I have similar symptoms like you, my feet are so numb can’t feel them, my legs are also numb and the numbness is now in my right hand.
I’m unable to hold certain things with it, and I’m learning to eat with my left hand.
Whole thing stinks,and I e been dealing with it for a few years now.
Whole thing started gradually about 10-11 yrs ago, and has progressed slowly.
No one is able to help me, and I’ve been on all the usual meds,that are prescribed by the docs.
