Hi - I am a 46 yo female, smoke 1/2 pack a day for about 3 years now, smoked 1 pack + for about 20 years before that. Healthy except for usual allergies, live in New Jersey, slight asthma, don't use an inhaler & never had an attack, use Advair when I get a cold. Had FESS (endoscopic sinus surgery) end of January, everything went fine until coming out of anetheszia and felt a bad tightness in my chest & difficulty breathing. Had an breathing treament. Ekg and chest x-ray came out ok. They thought it might be blood clot so had a CT w/contrast to rule out pulmonary embolism, which it did. Never did find out what the cause was, was told to get a stress test. Also to get a follow-up CT. But what worries me is the CT report which I just got yesterday. Sections of the report include the following: "scattered subcentimeter pulmonary nodules, mild dependent atelectatic changes noted at lung bases bilaterally, 5mm area of lucency within left lower lobe which may represent a small pneumatocele or emphysematous change, atherosclerotic changes are seen within the aorta, degenerative changes within thoracic spine with mutilevel Schmorl's nodes". This all sounds so bad!!! Am I reading too much into it? Help!
