It has been a year since I had chemotherapy and the numbness in my hands is still there but I believe it is subsiding. In addition to B6 and B 12 I bought a paraffin bath and soak my hands in the heated paraffin. It is not a cure but my hands are at least not so cold afterwards. For my feet I bought a pair of socks that have a sand filling. The filling is heated in the microwave and my feet stay warm for hours. These things at least make you feel better.
