Hi Robert,
I have colon cancer, and I have experienced exactly the same problems. I have had numbness and tingling in my hands and feet. My feet fall asleep quite often from sitting too long etc. The term used for this is neuropathy. I have had this problem with two different kinds of chemo drugs. I would suggest moving about as much as possible, and avoid sitting for any extended period of time. It is quite annoying, but I guess it is the price to pay for having chemotherapy. I like to soak my feet in a foot spa. The warm water feels good, and it helps the circulation. I would make sure it's ok with your doctor to use one. I always wear slippers while I'm in the house, and I keep my feet as warm as possible. I hope your doctor can give you some better advice. If it gets worse, I would ask the doctor for more information. The medication I am currently on is notorious for causing sensory problems. I want to wish you good luck with your treatments. Happy Holidays.
