question: I have wheezing/shortness of breath. Echocardiogram, chest X-rays showed normal. Doctor ruled out COPD, asthma, pulmonary fibrosis. O2 intake/lung capacity outstanding. Non smoker. Very fit. However, 282 pounds, but more importantly, I am taking cypionate ( prescribed by doctor) and anobolic steroid, which respiratory doctor doesn t know about. Getting sleep apnea test tomorrow. Doctor can t figure it out. My question
