the second times got the results i just previously stated. I took it twice because the first times it would indicate a very poor performance on my lungs' part. My lung function tests came back that I wasn't exhaling enough air, but after I quit smoking for 4 months, they came back that I was exhaling more than expected. I have had 3 CT scans, and several chest X-rays - all normal. I have been to the ER about a dozen times and have received a full cardiac workup including a thallium stress test, echocardiogram, and numerous EKGs - all of which were normal.
My chest hurts occasionally in the sternum area. My shortness of breath limits my abilities to speak long sentences and sing. It takes about 20 minutes or so to crack again, as a kunckle would. When I turn my chest, it cracks like my knuckles would. Right now, I have been feeling short of breath on and off daily. I am a 21 year old male who has experienced shortness of breath and chest pain on an on and off basis for almost a year.
