I just had this surgery done less than a week ago, and I'm finding myself short of breath. It turns out there is wheezing in my left lung. I start to feel better and then get extreme fatigue and shortness of breath again. I just started prednisone yesterday and an antibiotic. I think it's helping. But how are the sinus surgery and asthma related? I felt and still feel disbelieved by the doctors as well as how horrible I have been feeling post-op.
