IN the past 12 months I have had a progressive numbness and tingling in my feet and legs . It now involves my fingers and wrists area. It is not painful but has a sensation of numbness. I have been on high dosage of Vit. B Since it is progressing, I am in preparation to receive an intravenous immunoglobulin (IVIG) Treatment. Have any of you used this method for stabilizing the situation,or reversing the symptoms?
