I feel short of breath a lot but my doctor says my chest x-ray is clear.does this mean that my lungs are ok?

No: A chest xray might not pick up the early stages of copd, so might be normal with symptomatic disease. A pulmonary function test would be a better option for you.

No: Some unusual problems can cause dyspnea with a normal x-ray. Chronic pulmonary embolisms can do it, and pulmonary fibrosis in the early stage can look fairly normal on the x-ray. COPD also in the early stages can be there with a normal x-ray. You may need to see a pulmonary specialist to have additional testing to find out if your lungs are ok.

No: Shortness of breath can be from the "lungs" or from the "heart": a chest xray by itself does not rule out all the causes; more information is needed...

No: Chest x-ray can diagnose some lung conditions, but not others. Much more information is needed to even start answering this question. Age? Industrial exposures? Emotional issues? Findings on physical exam?.. More tests may be necessary, such as pulmonary function studies, and others. The diagnosis for this complaint can range from asthma to pulmonary fibrosis (unusual) to anxiety (most common).

No: A chest xray can be "clear" even when there are significant lung problems. In some cases, a ct chest may discover abnormalities that a chest xray did not. Your doctor can help determine this.
