Brief Answer:
You can opt for D-dimer testing
Detailed Answer:
Hi,
Thanks for your query.
Chest pain on deep breaths may be due to inflammation of pleural layer. Typical pattern is a localised pain which is sharp one and increases on maneuvers like deep inhalation, coughing,
sneezing etc. Chest xray may be normal at times. If you are having fever or other suggestive symptoms and high blood counts, you may take an empirical antibiotic course with an
analgesic...
Since your ECG is normal, it is less likely to be a cardiac anginal pain.
Pulmonary embolism may present with similar picture, this can be readily ruled out by a simple
blood test called D-dimer. IF it is less than 500, there is no pulmonary embolism. The test can be done provided that you are not bed ridden for days, pregnant, have trauma, stroke etc....in these situation its level comes rising and it is false postive....
Do meet your doctor for the same...
Best wishes
