Hi - I had CEF chemo, plus tamoxifen, and am now on Arimidex. I don't know if this helps, but I had terrible foot/arch pain, so bad that I could barely walk. Don't know if it was the result of chemo, or what. My doctor prescribed semi-intense Ibuprofen - 2 tabs every four hours daytime, every day. After 4 months, the foot pain disappeared, and it hasn't come back. Please ask your doctor if this might be appropriate for you - and ask about the neuropathy, also, as Phyllis suggests. Good luck - PJH
