Hi Chris,
I was reading your message and noticed that you're taking tykerb and xeloda. My mom is currently on both of those as well. She had a double mesectomy in 2000, and four years later, they found that it metastasized in her bones. In Aug of 2007, they found four tumors on her brain. They recently found that two of them were in really crucial areas, so she went through two different surgeries to get them removed. I'm surprised, although, that the herceptin didn't work well for you. It was working very well for her, but then her oncologist took her off it and placed her on the xeloda and tykerb regimen (2 weeks on, 1 off) and so far it's worked out pretty well. She's experienced severely dry skin, especially on her hands and feet. My advice to you is to buy Udderly Smooth lotion and apply it everyday to keep your skin in good condition. The diarrhea will most likely go away, because it did for my mom. Keep your head up Chris, you're going to get through this.
p.s. When the doctor asks you how you're feeling, say fine, but then agree to get scans done. My mom didn't want to get anything done because she said she was feeling fine, and before we knew it, she had gotten worse. Get tested, and don't just wait for the dr to give you the option, ask when you should.
