About 3 years ago, a blood clot went thru my lungs and heart and it almost killed me ! Now I have Afib and the left side of my diaphragm paralyzed ! And just last year I had a terrible case of pneumonia and that almost killed me ! My lungs are heart are in good condition but ever since my diaphragm became paralyzed, I've been short of breath ! I can't even shower that I can't breath, putting my cloths on is very difficult for me to breathe ! Everything I try to do is difficult for me to breathe ! I use oxygen at home most all the time !
