Hi, My brother inlaw has stage II cc, Had surgery, removed some of the colon ,no lymph involved,, he is on 5FU had 8th tx 4 wks ago, his feet are very numb and dr my cut doseage, but he is concerned that the numbess will get worse, or be permenet. has any of you had the numbness to the point that you could NOT walk??? His job would depend upon walking. Also wondering if having 8 tx would work?? I have read where some other people have taken 8 tx's and had to stop, but dont know if they went on different tx or not.. know this is kind of long,, but any help would really be apperacaited.... THANKS is advance
