I was diagnosed with breast cancer in 1997, had a mastectomy with no lymph node involvement. I had a recurrence in the chest wall in 1998 treated with surgery, radiation and tamoxifen. I have moved through Arimidexdex, FAC Chemotherapy, Aromasin, 6 cycles of Dosa Taxol plus Herceptin, Letrozole, and two years of Avastin and Xelodal. Since August, I have had weight loss, a persistent cough (with sputum, and light-headedness with one fainting spell. An October, 2010 Pet scan showed some cancer activity in a nodule in the lung and in the sternum. I have been on a drug holiday since November 2010, as my doctor tries to get results from a pulmonary function test. I have a colonoscopy scheduled for October 2011. My cough is getting worse, and yesterday I developed a pain in my mid rib-cage every time I cough.

Short term question: Is there some kind of cough suppression medicine I could take to prevent the pain of coughing?

Long term question:: Should I go somewhere like the Mayo Clinic to get an opinion my situation?
