I went in for a ct scan to see about nodules near my heart but they found on my left lung.I\'ve had pnemonia twice so the Dr thinks it could be scar tissue from passed episodes.But just make sure he has sceduled another ct scan to see if the nodule has increased in size.The nodule is on my left lung and the only systems I have is fatigue.I don\'t smoke or work around any hazzardous material.
