Has anyone had lung trouble since starting RA meds? I was diagnosed in October of 2013. First I took hydroxy, then added mtx. I changed to leflunomide and Humira last June. And I have had multiple courses of prednisone. Last month I had my first asthma attack ever. I first thought I was having a heart problem, but a pulmonary test confirmed lung inflammation/ asthma. I am wondering if the RA or the meds could be the culprit?
