Hi my name is Marg and i have been on this site for a few weeks now. After having a problem breathing after all the test they found out i had a damaged ventricle in my heart and also have artrial fillibration caused by chemo and radiation for breast cancer. A few weeks ago after more tests i now have copd. I was wondering if you know anyone with the same malady and what the up shot is. I live in Oz Queensland and the summers are hot and humid hard to breathe as well.
