I have foot and hand pain from Taxol, a cousin of Taxotere, that started about a year after I finished the Taxol. The kind of pain I have is called neuropathy and is caused by nerve damage from the chemo. Some of the other drugs you are taking could also have side effects that might affect your feet. A visit to the doctor could help you figure out whether this is a cancer treatment side effect or something else. The sooner you start treatment, the higher your chance of getting better. I hope you soon get some relief from this pain.
