My neurologist thought I had carpel tunnel also. He did the test on my wrist and everything came out positive for carpel tunnel. My hands are still numb and tingly. But the pain has gone away. For some reason the gbs residual just fooled him. I would wait and see what happens. goodluck to your,

good luck to your grandmother. My 5 Ivig’s were given daily for 5 days. That really worked for me.
