Numbness in the feet after chemotherapy is likely to be caused by peripheral neurotoxicity caused by chemotherapy drugs, and this kind of numbness can generally be relieved by no special medication. If it is a mild numbness, generally do not need special treatment, you can also try to take oral methylcobalamin tablets and other nerve-nourishing drugs. You should pay attention to the warmth of your feet, wear more comfortable socks and shoes, and soak your feet in warm water at night. Most of this neurotoxicity is reversible and will gradually recover after chemotherapy is finished, so there is no need to worry too much. In a very small number of patients, numbness in the feet can be particularly severe or even unbearable, so it is necessary to consider stopping chemotherapy drugs. If the condition requires continued chemotherapy, other chemotherapy drugs should be chosen.
