My hands are numb! I understand what you are going through. I keep cutting them while cutting carrots and onions to look down. And blood everywhere. Then go to ER to get stitches. IVIG does not cure the neuropathy but it slows down the progression of the disease. According to the medical journal of neurology takes 8 months to one year for it to work. . You have to remain on it for life. If you go off of IVIG it can fast track your symptoms. I have heard of Rituxan being used to treat RA and Lupus and other diseases but not neuropathy. You are not the first person trying it for neuropathy it’s an off label use my understanding.
