Ok....I was told that my swelling isn't from my heart, but because I have MS, Fibromyalgia etc...!!! She listened to my heart and lungs and she said that she can hear the "crakle" from my heart and lungs. And how my heart is really beating fast because of my left lung. Left lung and right of heart are both swollen. She said that she won't give me any water pills because she doesn't believe that I NEEDED IT!!! She wants me to stay on the oxygen like I'm doing, 24/7. I'm just so pissed and upset that I'm shaking now! I need to get out of these clothes and into something cooler.
