You mentioned in another post that we should have our heart and lungs checked while tapering off prednisone. I've never heard this before. Can I ask you why? I was on prednisone for a year and a half, starting at 60mg tapering to 0 over that time. I was off it for 6 months and now 4 days ago I had to go back on it due to a relaps of polymyositis ,but only 10mgs so far. I would imagine my doc will taper me off again one day but now I'm concerned because other than the usual listening to my heart and lungs at the doctor visits, nothing more was done. Please explain. :? Lu
