Urges to constantly deep breathe

Patient: I am a 53 year old male with discoid lupus and open heart surgery one year ago. cardiologist visit recently and doctor said ekg and blood pressure, weight and heart sound was good. been complaining last three weeks maybe four of urges to take a deep breath although it seems like its hard to do or expand my lungs to do. I get this urge often during the day, sometimes it can be every few minutes or sometimes spaced out through the day. annoying, doctor seems to think due to lupus, but not due to recent heart surgery. Scare tissue is keloiding and aggravating. i also see a VA dermatologist who injected the site with a steroid for scar tissue. CAn this be the lupus or my lungs or a reaction to the steroid injection. The only meds I take is aspirin medicine for gout, blood pressure and crestor.
