I don't know how common the twitching is for neuropathy or what it even means. I have everything on your list except for the weakness while twitching. My whole body especially my arms are weakened from what ever happened/is happening to me, but the twitching is random and migrates everywhere.
My neurologist hasn't said anything about it. He asks me if it is still happening when I see him and he just puts in in his computer. I think he is just waiting to see what happens with me.
