A year and a half ago I had a masectomy, then CEF chemo followed by taxotere, plus a year of Herceptin and also Tamoxifen. In addition I am on chlodrinate (a biphosphinate), calcium and vitamin D (I was diagnosed with stage 2 breast cancer, lymph node involvement, er pr positive, her2nu positive). I have been experiencing leg pain upon waking as well as foot pain on the soles of my feet, mostly the arch area. It hurts to walk. I am 37. Does any one have any experience with this? Any suggestions.
