i was diagnosed with asthma at age 2, in high school  i started smokig. at first it seemed to help ,but after a few years it made it hard to breath again but now with pain. i then stoped smoking its been 11 yr now . i only have an asthma attack now with high exercise but i always feel a little constriction. is it possible i now have emphysema ?
Dear, Possibility of Emphysema is not very likely. Your Asthma is well controlled and occurs only during exercise then we need to rule out other causes of chest constriction. I still recommend you to have Chest X-ray and Spirometry. If this comes normal then you need workup for your heart health to know the cause of chest constriction. You may go for TMT test and 2D ECHO of heart as well.
