I was just discharged yesterday from a 6 day hospital stay. Had pneumonia. I am on both Remicade and Prednisone. Started out 2 months ago with coug and shortness of breath. My primary did chest X Ray, Stress test, Pumonary Function studies. No antibiotic yet. Then I started a UC flare, increased my Pred from 5 mg/day to 40 mg/day. Flare cleared up in a few days and the s.o.b. improved. Started tapering the Pred, decreasing 10 mg/wk. Cough and S.O.B. came back by last week I was coughing up blood and so S.O.B. I could hardly walk around in my house. Saw my doctor on Friday, my PO2 was 77 and I was gasping for air. Was admitted that day. After enduring every test in the book, I was diagnosed with pneumonia. (They had to rule out TB, pulmonary embolism and did a bronchoscopy for good measure.)
By now I'm being followed by a pneumonologist who thinks the UC meds lowered my resistance so I picked up a bug of some sort, the Pred. masked my symptoms and by the time I tapered down on the Pred, I had developed pneumonia. There is also some thinking that UC can cause bleeding in the lung. This is a very long way to say, don't mess around with that cough. Go to some doctor and get checked out.
